Living with seizures is challenging enough, and when you’re prescribed medication like Briviact (brivaracetam), your main goal is to keep them under control while minimizing side effects. But here’s the reality: no medication works in isolation. The foods you eat, the alcohol you drink, the supplements you take, and even other prescriptions you rely on can all affect how Briviact works in your body.

Understanding these Briviact interactions isn’t just about maximizing effectiveness—it’s about staying safe. Some combinations may reduce seizure control, while others can increase the risk of dangerous side effects like drowsiness, mood changes, or coordination problems. In some cases, interactions can even become life-threatening if left unmanaged.

This detailed guide will break down everything you need to know about Briviact and its interactions in 2025, covering:

• How Briviact interacts with other antiseizure medications
• Antidepressants and mental health drug considerations
• Alcohol and recreational substances
• Supplements, herbs, and natural remedies
• Special health conditions that change how Briviact works
• Pregnancy and breastfeeding concerns
• Practical tips to avoid dangerous interactions

By the end, you’ll know exactly what to avoid, what to discuss with your doctor, and how to safely manage your treatment without unnecessary risks.

What Makes Briviact Different from Other Seizure Medications?

Before diving into the specific interactions, let’s quickly review why Briviact has become a go-to treatment for many patients.

• FDA-approved use: Briviact is primarily prescribed for partial-onset seizures in adults and children as young as 1 month old.
• How it works: Briviact binds to SV2A proteins in the brain, which play a key role in regulating abnormal electrical activity. This reduces the chances of seizures firing unpredictably.
• Why doctors prescribe it: Many patients who don’t fully respond to older drugs like Keppra (levetiracetam) may find Briviact more tolerable, especially when it comes to mood-related side effects.

However, like all medications, Briviact doesn’t exist in a bubble. It’s metabolized in the liver and interacts with the central nervous system—two areas heavily influenced by other drugs, supplements, and lifestyle factors.

Briviact Interactions with Other Medications

The most critical interactions to understand are with other prescription and over-the-counter drugs. Since many people taking Briviact also take antidepressants, antibiotics, or other antiseizure medications, knowing the risks is vital.

🔹 Briviact and Other Antiseizure Drugs

Sometimes, Briviact is prescribed alone (monotherapy), while other times it’s part of a combination therapy. But certain antiseizure drugs can speed up the breakdown of Briviact, making it less effective:

• Carbamazepine (Tegretol, Carbatrol)
• Phenobarbital (Sezaby)
• Phenytoin (Dilantin, Phenytek)
• Primidone (Mysoline)

When taken together, your body may clear Briviact too quickly, leaving you with sub-therapeutic levels—meaning seizures can still break through.

On the other hand, Briviact can slow down the breakdown of certain drugs, raising their levels in your bloodstream. This might increase side effects like fatigue, dizziness, or mood changes.

➡️ Real-world example: A patient on both Briviact and phenytoin may find their seizure control slipping, despite being “on medication.” Their doctor might need to increase Briviact’s dose or switch antiseizure drugs entirely.

🔹 Briviact and Antidepressants

Since seizures and mood disorders often overlap, many people on Briviact also take antidepressants. But some can create problems:

• Tricyclic Antidepressants (TCAs)—such as amitriptyline, imipramine, nortriptyline, and doxepin—can lower the seizure threshold, making seizures more likely.
• Trazodone (often used for sleep or depression) can worsen drowsiness when combined with Briviact.

If you’re on one of these medications, your doctor might:

1. Adjust your Briviact dosage
2. Switch you to a different antidepressant with fewer risks (like SSRIs or SNRIs)
3. Closely monitor your seizure activity

➡️ Expert tip: Never stop an antidepressant abruptly while on Briviact, as this can trigger both withdrawal symptoms and seizure instability.

🔹 Other Medications That Interfere with Briviact

Beyond seizure drugs and antidepressants, a few other prescriptions can reduce Briviact’s effectiveness by accelerating its metabolism:

• Apalutamide (Erleada) → used for prostate cancer
• Hydroxychloroquine (Plaquenil) → used for lupus, arthritis, malaria prevention
• Rifampin (Rifadin, Rimactane) → antibiotic for tuberculosis and serious infections

If you’re prescribed any of these, expect your neurologist to adjust your Briviact dose—or, in some cases, recommend an alternative antiseizure medication.

Briviact and Alcohol: Why This Combination Is Risky

One of the most common questions patients ask is:
👉 “Can I drink alcohol while taking Briviact?”

The short answer is no—and here’s why.

Both alcohol and Briviact act on the central nervous system (CNS). When combined, their effects don’t just “add up”—they can multiply, leading to dangerous consequences.

🔹 Side Effects That Get Worse with Alcohol

Drinking alcohol while taking Briviact can significantly increase the severity of these side effects:

• Drowsiness and fatigue → You may feel excessively tired, sluggish, or “out of it.”
• Dizziness and poor balance → A higher risk of falls, accidents, and injuries.
• Slowed thinking and reaction times → Dangerous if you’re driving, working, or operating machinery.
• Impaired judgment → Risky behaviors can increase when your decision-making is compromised.

➡️ Real-world risk: A person on Briviact who has just two glasses of wine may feel as though they’ve had double that amount. Their coordination and focus drop dramatically, raising the risk of falls, car accidents, or workplace mistakes.

🔹 Alcohol and Seizure Control

There’s another hidden danger: alcohol itself can lower the seizure threshold, making it more likely that seizures will break through—even if your Briviact levels are stable.

This means alcohol not only undoes the effectiveness of your medication but can actually trigger the very condition Briviact is meant to prevent.

➡️ For someone with a seizure disorder, even small amounts of alcohol can be destabilizing. A night of heavy drinking followed by a hangover increases seizure risk even further.

🔹 The Long-Term Effects of Mixing Briviact and Alcohol

Occasional drinking is risky enough, but regular alcohol use while on Briviact can lead to:

• Worsening side effects (chronic fatigue, brain fog, depression)
• Unstable seizure control (leading to ER visits and hospitalization)
• Strain on the liver, which is already processing Briviact
• Higher risk of dependence since Briviact is a controlled substance and alcohol itself can be addictive

---

Should You Completely Avoid Alcohol on Briviact?

Most doctors will say yes, avoid it entirely—especially during the early stages of treatment, when your body is still adjusting to Briviact.

However, some patients ask about occasional light drinking (like one glass of wine with dinner). While this may be less risky than heavy drinking, it’s still important to:

1. Ask your doctor first → Individual tolerance varies.
2. Time it carefully → Drinking close to when you take Briviact increases interaction risk.
3. Never mix with other CNS depressants → Avoid combining alcohol with sleeping pills, anxiety meds (like benzodiazepines), or opioids while on Briviact.

➡️ Important note: Alcohol is found in more than just beverages. Some prescription cough syrups, liquid medications, and herbal tinctures also contain alcohol. Always check labels or ask your pharmacist.

---

Safer Alternatives to Alcohol While on Briviact

If you’re looking for ways to unwind or celebrate without alcohol, consider:

• Mocktails made with sparkling water, fruit juice, and fresh herbs
• CBD-free herbal teas (chamomile, lemon balm, rooibos)
• Non-alcoholic beer or wine (choose versions with 0.0% ABV, not “low-alcohol”)
• Meditation, yoga, or breathing exercises for stress relief

These options allow you to socialize and relax without compromising your safety or seizure control.

---

Key Takeaways: Briviact and Alcohol

• Even small amounts of alcohol can worsen Briviact’s side effects and increase seizure risk.
• Alcohol puts extra strain on the liver, slowing down Briviact metabolism and raising toxicity risks.
• Avoid mixing Briviact, alcohol, and other CNS depressants (sleeping pills, anxiety meds, opioids).
• Safer alternatives like mocktails, herbal teas, and relaxation techniques can help you manage cravings or social pressure without compromising health.

Briviact and Supplements: What You Should Know

Many people assume that because vitamins, minerals, and herbs are “natural,” they’re automatically safe. Unfortunately, this isn’t always true—especially when you’re taking a powerful antiseizure medication like Briviact.

Some supplements can change how your body processes Briviact, while others may worsen side effects or even trigger seizures.

Let’s break down the most important supplement and herbal interactions with Briviact in 2025.

---

🔹 St. John’s Wort: The #1 Supplement to Avoid

St. John’s Wort is one of the most well-known herbal remedies for depression, stress, and mood swings. But it’s also one of the worst supplements to take with Briviact.

Why? Because it:

• Speeds up liver enzymes that metabolize Briviact
• Lowers the drug’s blood levels, making it less effective
• Raises seizure risk by undermining treatment

➡️ Example: A patient taking Briviact for partial-onset seizures starts St. John’s Wort for mild depression. Within weeks, seizure frequency increases—not because Briviact stopped working, but because the herb reduced the amount of medication in their body.

✅ If you’re struggling with mood symptoms, talk to your doctor. Safer alternatives (such as SSRIs or therapy) may be available.

---

🔹 CBD and Cannabis Products

Cannabis and CBD (cannabidiol) are increasingly popular for stress relief, sleep, and even seizure management. However, combining them with Briviact requires caution.

• CBD is processed by the liver, just like Briviact → this can lead to higher or unpredictable Briviact levels.
• THC (the psychoactive compound in cannabis) can impair memory, coordination, and focus → side effects that overlap with Briviact.
• Medical cannabis users should work closely with their neurologist → some strains or formulations may be safer than others.

➡️ Bottom line: Cannabis products haven’t been proven safe with Briviact. Always disclose CBD or cannabis use to your doctor so they can monitor you for side effects or dose adjustments.

---

🔹 Vitamin and Mineral Supplements

Most standard vitamins and minerals don’t directly interact with Briviact. However, there are a few important considerations:

• Magnesium and calcium supplements may cause mild digestive upset when taken with Briviact → try spacing them a few hours apart.
• Vitamin D and calcium are often recommended for people with epilepsy since long-term antiseizure use may affect bone health.
• High-dose supplements (especially herbal blends or “energy boosters”) should always be checked with your pharmacist.

---

🔹 Herbal Remedies and Natural Products

Several popular herbal remedies can create risks for people on Briviact:

• Kava → increases sedation and drowsiness when combined with Briviact
• Valerian root → often used for sleep, but adds to dizziness and fatigue
• Ginkgo biloba → sometimes lowers seizure threshold, raising the risk of breakthrough seizures
• Kratom → can interact with liver metabolism and CNS function, potentially very dangerous with Briviact

➡️ Even essential oils (like oregano or peppermint oil) can be risky if taken internally in capsule form. Stick to safe, doctor-approved supplements.

---

🔹 Protein Powders & Fitness Supplements

Many people with active lifestyles use protein powders, pre-workout mixes, or energy boosters. While most protein powders are safe, watch out for hidden stimulants like:

• Caffeine (in high doses) → can worsen anxiety, insomnia, or seizure risk
• Yohimbine → linked to seizures in sensitive individuals
• Synephrine (“bitter orange”) → can overstimulate the nervous system

Always check the label before adding a new supplement to your routine.

---

Safe Supplement Strategies for People on Briviact

If you’re considering supplements, here are some safe steps to follow:

1. Make a full supplement list → Write down all vitamins, minerals, herbs, and over-the-counter products you take.
2. Check with your doctor or pharmacist → Before starting anything new, confirm it’s safe with Briviact.
3. Avoid high-dose or “proprietary blend” products → These often hide risky stimulants or herbs.
4. Look for epilepsy-safe nutrients → Vitamin D, calcium, and omega-3 fatty acids are often safe and beneficial.
5. Monitor side effects → If you notice more drowsiness, mood changes, or breakthrough seizures after starting a supplement, stop and call your doctor.

---

Key Takeaways: Briviact and Supplements

• St. John’s Wort is the biggest herbal danger → avoid it completely.
• CBD and cannabis may affect Briviact levels → always tell your doctor if you use them.
• Most basic vitamins are safe, but high-dose or stimulant-based supplements can increase risks.
• Herbal remedies like kava, valerian, and ginkgo may worsen side effects or seizures.
• Always check new supplements with your healthcare team before starting them.

Health Conditions That Can Affect Briviact Safety and Effectiveness

Briviact (brivaracetam) is generally well tolerated, but your overall health plays a big role in how safe and effective the medication will be. Some conditions can increase side effects, while others may require dosage adjustments or closer monitoring from your doctor.

Here’s a detailed breakdown of the most important health conditions to consider if you’re taking Briviact.

---

🔹 Liver Problems

The liver is the main organ responsible for breaking down Briviact. If your liver isn’t working properly, the drug may stay in your system longer than intended, leading to higher levels and stronger side effects.

What This Means for You

• People with mild liver impairment may need a lower starting dose of Briviact.
• People with moderate to severe liver disease (such as cirrhosis or hepatitis) need careful monitoring to avoid drug buildup.
• In some cases, your doctor may choose a different antiseizure medication that’s easier on the liver.

Common Symptoms of Drug Buildup in Liver Patients

• Extreme drowsiness
• Confusion or brain fog
• Severe dizziness
• Trouble with coordination

➡️ If you have any liver condition, make sure your doctor knows before starting Briviact. Blood tests may be needed regularly to check liver function.

---

🔹 Mental Health Conditions

Like many antiseizure medications, Briviact can affect mood and behavior. The FDA includes a warning that drugs in this class may increase the risk of suicidal thoughts or behaviors in a small number of patients.

Higher-Risk Groups Include:

• People with depression
• Those with bipolar disorder
• Individuals with a history of anxiety or mood disorders
• Patients with a family history of suicide or major psychiatric illness

Possible Mental Health Side Effects of Briviact

• Irritability
• Mood swings
• Depression or worsening of existing depression
• Aggression or unusual anger
• Suicidal thoughts in rare cases

➡️ Doctors often screen for mental health history before prescribing Briviact. If you have a mood disorder, you can still take Briviact safely — but you’ll need closer monitoring in the first few months and after any dose change.

Tip: Keep a mood diary when starting Briviact. If you or your loved ones notice sudden changes in behavior, call your doctor immediately.

---

🔹 Substance Use History

Briviact is a Schedule V controlled substance in the U.S. because it has a small but real potential for dependence or misuse.

Who Needs Extra Caution?

• People with a history of alcohol use disorder
• People with a history of opioid misuse
• Those who have misused benzodiazepines or sedatives
• Individuals with polysubstance abuse history

Briviact misuse is rare, but it can happen, especially if someone is taking it for nonmedical reasons (such as trying to enhance mood or sedation).

➡️ If you’ve had substance use struggles in the past, your doctor may:

• Choose Briviact only if it’s the best option
• Prescribe smaller quantities at a time
• Schedule more frequent check-ins to monitor progress

---

🔹 Pregnancy and Breastfeeding

For people planning a family or already pregnant, Briviact requires special consideration.

Pregnancy

• Research is limited on Briviact’s safety in pregnancy.
• Animal studies suggest possible risks to the developing baby, but human data is still lacking.
• Stopping Briviact suddenly during pregnancy can cause severe, uncontrolled seizures, which can be dangerous for both mother and baby.
• Women who become pregnant while taking Briviact are encouraged to enroll in the Briviact Pregnancy Registry (phone: 1-888-233-2334) to help doctors gather more safety information.

Breastfeeding

• Briviact does pass into breast milk.
• The effects on nursing babies are not fully known.
• Doctors may recommend either avoiding breastfeeding or monitoring the infant for sedation, feeding difficulties, or unusual behavior.

➡️ Always tell your neurologist if you’re pregnant, planning to become pregnant, or breastfeeding. Together, you can weigh the risks and benefits to choose the safest treatment plan.

---

🔹 Other Health Considerations

• Kidney Disease: Briviact is not significantly cleared by the kidneys, so mild kidney problems usually don’t affect treatment. Severe kidney disease, however, may still require caution.
• Sleep Disorders: Since Briviact can cause drowsiness, people with conditions like sleep apnea may be at higher risk of excessive daytime sleepiness.
• Balance Disorders: If you already have issues with dizziness or vertigo, Briviact may worsen coordination problems.

---

Key Takeaways: Briviact and Health Conditions

• Liver disease → Slows down drug clearance; dose adjustments often required.
• Mental health conditions → May increase risk of mood changes or suicidal thoughts.
• Substance use history → Extra caution needed due to misuse potential.
• Pregnancy & breastfeeding → Limited research, but stopping suddenly is dangerous.
• Other conditions → Sleep and balance disorders may worsen with Briviact.

Briviact and Food Interactions

One of the reassuring things about Briviact is that it does not have significant food interactions. Unlike some seizure medications that must be taken on an empty stomach or with food for proper absorption, Briviact gives patients more flexibility.

✅ Key Points About Briviact and Food

• You can take Briviact with or without meals.
• High-fat meals do not significantly change absorption.
• Consistency matters most — try to take it at the same time every day to keep levels steady.

Hydration Tip

Some patients report mild dizziness or headaches when starting Briviact. Drinking enough water throughout the day can help reduce these side effects.

➡️ Bottom line: There are no strict food restrictions with Briviact, but building a routine with consistent timing can improve seizure control and reduce side effects.

---

Briviact and Laboratory Test Interactions

When taking long-term medications, many patients worry whether their prescriptions could skew blood test results. Good news: Briviact does not interfere with common laboratory tests.

✅ Safe Tests While on Briviact

• Standard blood counts
• Liver function tests (important for monitoring Briviact use itself)
• Kidney function tests
• Thyroid function panels
• Cholesterol and glucose panels

Why Monitoring Still Matters

Even though Briviact doesn’t distort lab results, your doctor may order routine liver tests since the drug is metabolized in the liver. This is especially important if you also take other medications that affect liver health.

➡️ Always tell lab staff and your doctor about your full medication list, even if Briviact itself isn’t known to interfere.

---

Preventing Dangerous Briviact Interactions

The most powerful step in managing Briviact safely is proactive prevention. By following a few practical strategies, you can minimize risks and get the best results from your treatment.

---

🔹 1. Communicate with Your Healthcare Team

Always keep all your providers in the loop:

• Your neurologist (who prescribes Briviact)
• Your primary care doctor
• Your pharmacist
• Any specialists (psychiatrists, cardiologists, etc.)

Why it matters: If one doctor doesn’t know what another has prescribed, you could end up with a dangerous interaction.

---

🔹 2. Keep an Updated Medication List

Create a written or digital list of everything you take:

• Prescription drugs (name, dose, frequency)
• Over-the-counter meds (pain relievers, cold medicine, sleep aids, etc.)
• Supplements (vitamins, herbs, protein powders, etc.)
• Recreational substances (alcohol, cannabis, nicotine, etc.)

➡️ Keep a copy in your wallet or on your phone. Share it whenever you see a new healthcare provider.

---

🔹 3. Read Labels Carefully

Prescription bottles and over-the-counter medications often have warning stickers such as:

• “Do not take with alcohol.”
• “May cause drowsiness.”
• “Ask your doctor before use if you take antiseizure medication.”

Always check for hidden alcohol in liquid cough syrups or cold medicines. Even small amounts can worsen Briviact side effects.

---

🔹 4. Follow Dosing Instructions Precisely

• Take Briviact at the same times daily.
• Do not skip doses (this can trigger breakthrough seizures).
• Do not double up if you miss a dose — follow your doctor’s guidance.
• Never stop Briviact suddenly; doing so could cause severe, uncontrolled seizures.

---

🔹 5. Watch for Red-Flag Symptoms

Seek medical attention if you experience:

• Severe mood changes (aggression, depression, suicidal thoughts)
• Allergic reaction symptoms (swelling, rash, difficulty breathing)
• Unusual fatigue, confusion, or dizziness
• Signs of liver problems (yellow skin/eyes, dark urine, abdominal pain)

For emergencies (such as suicidal thoughts or seizures that don’t stop), call 911 immediately.

---

Key Takeaways

• Briviact does not interact with foods and does not interfere with lab test results.
• The biggest risks come from drug, alcohol, and supplement interactions — not food.
• Preventing dangerous interactions means:
  • Keeping all providers informed
  • Maintaining an updated medication list
  • Following dosing instructions carefully
  • Watching for early warning signs of trouble
