What is Omvoh?

Omvoh is a brand-name biologic medication that contains the active ingredient mirikizumab-mrkz, a specially engineered monoclonal antibody. Unlike traditional chemical-based drugs, biologics are created from living cells, making them highly targeted in their effects.

Since Omvoh is a biologic, it does not have a generic version—only biosimilars may become available in the future once its exclusivity period ends.

How Omvoh Works

Ulcerative colitis is fueled by chronic inflammation in the large intestine. The immune system mistakenly attacks healthy tissue, leading to ulcers, bleeding, abdominal pain, and diarrhea. Omvoh works by blocking a specific protein in the inflammatory pathway, calming the overactive immune response, and reducing damage to the colon.

This targeted approach makes it different from traditional medications like corticosteroids or immunosuppressants, which often affect the immune system more broadly and carry higher risks of side effects.

Administration Options

Omvoh is available in two forms, depending on your stage of treatment:

• Intravenous (IV) infusion: Administered at a hospital, clinic, or infusion center.
• Subcutaneous injection: Administered at home (after proper training) using prefilled injection pens.

This flexibility allows patients to begin treatment under close medical supervision before transitioning to a more convenient at-home injection schedule.

What Conditions Does Omvoh Treat?

FDA-Approved Use

Currently, Omvoh is FDA-approved specifically for the treatment of ulcerative colitis in adults with moderate to severe symptoms.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that affects the colon and rectum. It causes persistent inflammation, open sores (ulcers), and a wide range of symptoms that can severely impact daily life.

Common UC symptoms include:

• Persistent diarrhea, often with blood or mucus
• Abdominal cramping and pain
• Unexplained fatigue and weakness
• Loss of appetite and unintended weight loss
• Urgency to use the bathroom
• Blood in stool

For many people, these symptoms flare up unpredictably, making UC difficult to manage with lifestyle adjustments alone.

Who Can Use Omvoh?

Omvoh is approved for adults only. At this time, it is not recommended for children or adolescents because its safety and effectiveness have not been studied in younger age groups.

Doctors typically prescribe Omvoh for:

• Patients who have not responded well to conventional treatments (such as steroids, immunosuppressants, or aminosalicylates).
• Individuals who have experienced severe side effects from other medications.
• Patients looking for a more targeted therapy to better control inflammation.

By offering a new option for patients who have struggled with existing treatments, Omvoh provides an important step forward in UC management.

Omvoh Dosage and Administration Guidelines

Getting the dosage and schedule right is critical to the effectiveness of Omvoh. Treatment usually begins under medical supervision and then transitions to at-home care.

Initial Treatment (Induction Phase)

• 300 mg IV infusion every 4 weeks for the first three doses.
• Each infusion takes about 30 minutes.
• Infusions are given at a hospital, clinic, or infusion center where medical staff can monitor for side effects.

Maintenance Phase

• Starting with the fourth dose, patients switch to 200 mg subcutaneous injections every 4 weeks.
• This requires two injections (100 mg each) using prefilled pens.
• After proper training, most patients can self-administer injections at home, offering greater convenience.

Available Forms of Omvoh

• Single-dose vial for IV infusion: 300 mg/15 mL solution.
• Prefilled injection pens: 100 mg/mL solution.

Injection Sites for Subcutaneous Doses

• Thigh (commonly recommended for self-administration).
• Abdomen (avoiding a 2-inch radius around the belly button).
• Upper arm (requires another person to assist).

Missed Dose Instructions

• If you miss an infusion, call your clinic immediately to reschedule.
• If you miss a home injection, take it as soon as you remember. Then continue with your regular 4-week schedule.

Consistency is crucial for controlling UC symptoms, so setting reminders or using a medication-tracking app can help prevent missed doses.

Omvoh Side Effects

Like all medications, Omvoh can cause side effects. While many are mild and temporary, some require medical attention.

Common Side Effects

These are usually short-lived and improve as the body adjusts:

• Headache
• Injection site reactions (redness, swelling, mild pain)
• Joint pain
• Skin rash
• Mild infections (such as colds)
• Mild allergic reactions (itching, irritation)

Serious Side Effects

Though less common, some side effects require immediate medical attention:

1. Serious infections
   • Pneumonia (fever, chest pain, difficulty breathing)
   • Shingles (painful, blistering rash on one side of the body)
   • Other opportunistic infections
2. Liver problems
   • Yellowing of the skin or eyes (jaundice)
   • Dark urine
   • Persistent nausea or vomiting
   • Unusual fatigue
3. Severe allergic reactions
   • Difficulty breathing
   • Swelling of face, lips, tongue, or throat
   • Severe skin reactions

Managing Side Effects

• Mild side effects often resolve without intervention. Over-the-counter remedies (like acetaminophen for headaches) may help.
• Moderate to severe side effects should always be discussed with a healthcare provider.
• Signs of infection or severe allergic reactions require urgent medical attention.

Patients should never ignore new or worsening symptoms. Since Omvoh impacts the immune system, infections can become serious if left untreated.

Drug Interactions with Omvoh

Like other biologic medications, Omvoh can interact with certain treatments, particularly those affecting the immune system. Understanding these interactions helps prevent complications.

Vaccine Interactions

The most significant concern is with live vaccines. Because Omvoh modifies the immune response, live vaccines may not work as intended or could trigger infections.

Examples of live vaccines to avoid while taking Omvoh include:

• Chickenpox (Varivax)
• Measles, mumps, rubella (MMR)
• Live influenza vaccine (nasal spray)
• Yellow fever vaccine

Safer alternatives: Inactivated (non-live) vaccines such as the injectable flu shot or COVID-19 vaccines are generally safe, but timing may need to be adjusted. Always check with your doctor before receiving any vaccine while on Omvoh.

Other Medications

Currently, there are no widely reported interactions between Omvoh and common prescription or over-the-counter drugs. However, since it is still relatively new, research is ongoing. Patients should always:

• Share a complete medication list with their healthcare provider.
• Include supplements and herbal remedies, as some can affect the immune system.
• Notify doctors before starting any new medication while on Omvoh.

Alcohol Considerations

Alcohol does not directly interfere with Omvoh. However, it can worsen ulcerative colitis symptoms, such as diarrhea and abdominal pain. Drinking alcohol can also make it harder to tell if your symptoms are due to UC, side effects, or alcohol itself. Patients should discuss safe limits with their healthcare provider.
