Migraine is a disorder characterized by mild to acute attacks of headache accompanied by nausea and vomiting. Its other symptoms include sensitivity to light (photophobia) and sound (phonophobia).

A migraine attack may last from a few hours to three days. Its occurrences could range from twice a week to once or twice a year. It may or may have not a warning signs before an attack. While some people experience a warning sensation such as weakness, numbness in an arm or leg or light flashes with headaches every 20 or 30 minutes, most individual do not undergo these alerts.

Common anti-migraine drugs and side effects

Renal failure and stomach upsets are the most common complaint in anti-migraine drugs particularly with the NSAIDS (mefenamic, diclofenac, ibuprofen etc.). While vasoconstrictors as ergotamine can cause heart attack or stroke, triptans like sumatriptan and zolmitriptan can have an intolerable unpleasant effect of pressure or heaviness.

Migraine-headaches can be a burden. There are natural ways to counteract or prevent migraine attacks. However, most people still rely on drugs. Analgesics, vasoconstrictors and the triptans are typically the common drugs for migraine. An anti-nausea drug like flunarizine is also indicated for migraines associated with intolerable dizziness.

There are also preventive or prophylactic drugs for migraine. Interestingly, pizotifen - a popular appetite stimulant is one of these.

Pizotifen as an Anti-migraine Drug

As a prophylactic medication, pizotifen can reduce the occurrence and period of migraine headaches but will not eliminate the condition. Although it can be an effective choice as prevention for migraine without the unpleasant side effect of heaviness, stomach upsets or liver problems, its use is still limited because of its untoward reactions as drowsiness and weight gain. With this, other prophylactic migraine drugs which include the cyclandelate, valproic acid, magnesium, the antidepressant amitriptyline, beta blockers propranolol and the calcium channel blocker verapamil are used in place of this drug. Pizotifen is not effective in relieving a migraine attack once in progress of if the pain has already begun.
