Does Vyepti cause weight gain?
No, weight gain was not seen in safety studies of Vyepti lasting up to one year long. In general, Vyepti is well tolerated, with less than 2% of patients dropping out of clinical studies due to side effects. According to the manufacturer, a pharmacokinetic study looking at the effects of age, race, sex, and body weight did not suggest any clinically significant impact due to Vyepti.
Vyepti (eptinezumab-jjmr), a calcitonin gene-related peptide antagonist, was the first FDA-approved IV treatment for migraine prevention in adults.
What side effects do I expect to see with Vyepti?
Safety studies included over 2,000 adult patients receiving either the 100 or 300 mg dose of Vyepti for migraine prevention.
The most common side effects were common cold symptoms like stuffy nose and scratchy throat (6% to 8% of patients taking Vyepti vs. 6% placebo) and allergic (hypersensitivity) reactions (1% to 2% of patients taking Vyepti vs. 0% placebo).
Some allergic reactions, such as anaphylaxis, may be serious. If you have symptoms of an allergic reaction, contact your doctor or get emergency medical care right away. These symptoms can include:
- rash
- swelling of your face, lips, tongue or throat
- problems breathing
- hives
- redness (flushing) of your face
Other side effects may include high blood pressure and Raynaud’s phenomenon.
- Contact your healthcare provider if you have an increase in blood pressure.
- Raynaud’s phenomenon is a type of circulation problem that can occur or get worse after receiving this treatment. You may notice your fingers or toes feeling numb, cool, painful or changing color (from pale to blue to red). Contact your healthcare provider if these symptoms occur.
These are not all of the possible side effects of Vyepti. If you have further questions or concerns about side effects contact your healthcare provider. To learn more, review the section on Side Effects of Vyepti.
How is Vyepti given?
The recommended dose is 100 mg intravenously (IV) given every 3 months. Some patients may benefit from a higher dose of 300 mg. The infusion takes about 30 minutes and is only given by your healthcare provider.

How well does Vyepti work to prevent migraine?
In two Phase 3 clinical studies of Vyepti (PROMISE-1 in episodic migraine and PROMISE-2 in chronic migraine), researchers were looking to see how many fewer days of migraine headaches patients had over a 12-week period. At the start of the study, on average, patients had 8.6 migraine days per month.
- An episodic migraine usually results in fewer than 15 headache days per month, and the headache usually lasts less than 24 our per episode.
- On the other hand, a chronic migraine involves 15 or more headache days per month for at least 3 months, each headache lasting more than 24 hours, and may be more severe. On at least 8 of those days, you must have migraine symptoms like sensitivity to light, sensitivity to sound, or nausea).
In the episodic migraine study, the number of mean monthly migraines dropped by 3.9 days for the 100 mg dose and by 4.3 days for the 300 mg dose, compared to 3.2 fewer days in the placebo group.
In the chronic migraine study, the number of mean monthly migraines dropped by 7.7 days for the 100 mg dose and by 8.2 days for the 300 mg dose, compared to 5.6 fewer days in the placebo group.
Vyepti also exhibited a benefit over placebo for both the 100 and 300 mg doses of Vyepti as early as the first day after treatment, according the studies conducted by the manufacturer. The percentage of patients experiencing a migraine was lower for Vyepti than with placebo for most of the first 7 days.
Vyepti is classified as a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor.
