What is a migraine and how does it differ from other headaches?
A migraine is an intense, throbbing, typically one-sided headache. It often includes nausea, vomiting, sensitivity to light, and sensitivity to sound. The pain and symptoms from a migraine headache may be worse than the pain and symptoms of a common headache.
Some people have visual symptoms before the headache, such as flashing lights or wavy lines, called an aura.
Migraine attacks typically last for hours or, rarely, for more than a day. They can return often. The strength and frequency of migraine attacks may vary.
Based on your symptoms, your doctor will decide whether you have a migraine.
Migraine headaches tend to occur in members of the same family. Both men and women get migraines, but it is more common in women.
What may trigger a migraine attack?
Certain things may trigger migraine attacks in some people. Some of these triggers are:
- certain foods or drinks, such as cheese, chocolate, citrus fruit (oranges, grapefruit, lemons, limes, and others), caffeine, and alcohol.
- a change in behavior, such as too much or too little sleep, missing a meal, or a change in diet.
- hormone changes in women, such as during monthly menstrual periods.
You may be able to prevent migraine attacks or make them come less often if you understand what triggers your attacks. Keeping a headache diary may help you identify and monitor the possible triggers that cause your migraine. Once you identify the triggers, you and your doctor can change your lifestyle to avoid those triggers.
How does AXERT® work during a migraine attack?
Treatment with AXERT®:
- reduces swelling of blood vessels surrounding the brain. This swelling is associated with the headache pain of a migraine attack.
- blocks the release of substances from nerve endings that cause more pain and other symptoms of migraine.
- interrupts the sending of specific pain signals to your brain.
It is thought that each of these actions contributes to relief of your symptoms by AXERT® .
How should I store AXERT®?
Keep your medicine in a safe place where children cannot reach it. It may be harmful to children. Store your medicine away from heat, light, or moisture at a controlled room temperature. If your medicine has expired, throw it away as instructed. If your doctor decides to stop your treatment, do not keep any leftover medicine unless your doctor tells you to do so. Throw away your medicine as instructed. Be sure that discarded tablets are out of the reach of children.
General advice about prescription medicines
Medicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. Do not use AXERT® for a condition for which it was not prescribed. Do not give AXERT® to other people even if they have the same symptoms you have. People may be harmed if they take medicines that have not been prescribed for them.
This leaflet provides a summary of information about AXERT®. If you have any questions or concerns about either AXERT® or migraines, talk to your doctor. In addition, talk to your pharmacist or other healthcare provider.
