Migrex is a prescription medicine used to treat migraine attacks with or without aura in adults. This medication contains frovatriptan 2.5 mg, a medication from the triptan class that works by narrowing widened blood vessels in the brain to help relieve migraine pain and associated symptoms.
The brand name Migrex may contain different active ingredients in different countries. In the United States, frovatriptan 2.5 mg is approved for migraine treatment, although it is marketed under different brand or generic names. The Migrex offered here contains the same active ingredient, strength, and clinical use as approved frovatriptan tablets.
Migrex is intended to treat a migraine after it has started and is not used to prevent migraines.

Migrex is indicated for the acute treatment of migraine with or without aura in adults.
Approved use:
Limitation of use:
Migrex works through its active ingredient, frovatriptan, which affects serotonin receptors involved in migraine pain. The ingredient itself binds with high affinity to 5-HT1B/1D receptors on intracranial blood vessels and trigeminal sensory nerves. Its therapeutic effect is thought to result from:
Together, these actions help relieve migraine pain by targeting blood vessel changes and pain signaling involved in migraine attacks.
Always follow your healthcare provider’s instructions. General guidelines include:
Migrex is not intended for daily use and should not be taken to prevent migraines.
The dosage of Migrex is used for the acute treatment of migraine attacks in adults and should be taken exactly as directed by a healthcare provider.

Taking more than the recommended dose of Migrex (frovatriptan) may increase the risk of side effects and require medical attention. If an overdose is suspected:
There is no specific antidote for frovatriptan overdose. It is unknown whether dialysis effectively removes the medication from the body. Do not exceed the prescribed dose or take Migrex more frequently than directed. Always follow your healthcare provider’s instructions.
Migrex (frovatriptan) may cause side effects in some people. While many users tolerate it well, certain reactions can be serious and require immediate medical attention. Commonly reported Migrex side effects are listed below:
Stop taking Migrex and get urgent medical care if you experience:
Heart-related problems:
These may be signs of a heart attack.
Stroke symptoms:
Migrex should not be used to treat headaches that are unusual, sudden, or not clearly diagnosed as migraine.
Circulation problems:
Stomach or intestinal problems:
Serotonin syndrome (rare but serious, especially when used with antidepressants):
Allergic reactions:
Medication overuse headache:
If any side effects bother you, last longer than expected, or worsen, contact your healthcare provider.
Frovatriptan in Migrex affects blood vessels in the brain. Due to this, it may cause serious side effects in certain individuals, particularly those with underlying heart, blood vessel, or neurological conditions. Always use this medication exactly as prescribed and inform your doctor of your complete medical history before starting treatment.
Various precautions should be taken when taking this medication. Tell your doctor if you have:
Migrex should be used cautiously in people who are new to triptan therapy, especially if multiple cardiovascular risk factors are present. In some cases, a cardiac evaluation may be required before the first dose.
This medication may rarely cause serious and potentially life-threatening reactions.
Heart and blood vessel-related risks:
Neurological and other serious risks:
Stop taking Migrex and seek immediate medical attention if you experience chest pain, shortness of breath, sudden weakness, vision changes, confusion, severe abdominal pain, or symptoms of serotonin syndrome.
Pregnancy:
There are no adequate studies on the use of Migrex in pregnant women. Animal studies have shown embryofetal toxicity at doses significantly higher than those used in humans. Poorly controlled migraines during pregnancy may also increase risks such as preeclampsia. It should be used during pregnancy only if clearly needed and if the potential benefit outweighs the possible risk to the fetus.
Breastfeeding:
It is unknown whether frovatriptan passes into human breast milk. Animal studies have shown drug levels in milk higher than in blood. Breastfeeding mothers should consult their healthcare provider about the risks and benefits of continuing breastfeeding or discontinuing the medication.
Migrex (frovatriptan) may interact with certain medicines that affect blood vessels or serotonin levels. Some combinations can increase the risk of serious side effects and should be avoided.
Ergot-containing medicines:
Ergot-containing drugs can cause prolonged narrowing of blood vessels. Using these medicines together with Migrex may lead to severe vasospastic reactions.
Other triptans (5-HT1B/1D agonists):
Migrex should not be taken with other triptan medicines, as their blood vessel–constricting effects may be additive.
Antidepressants and Serotonin-affecting medicines:
Using Migrex with medicines that affect serotonin levels may increase the risk of serotonin syndrome, a potentially serious condition.
This is not a complete list of all possible drug interactions. Always inform your healthcare provider about all over-the-counter drugs, supplements, and prescription medicines you are taking before using Migrex.
Depending on migraine severity, treatment response, cardiovascular risk factors, and individual tolerance, doctors may recommend alternative migraine medications instead of Migrex.
