Migraines are devastating headaches that cause a host of other symptoms, such as nausea and sensitivity to light and sound. Although pain medications may ease the symptoms of a migraine, those who experience frequent migraines may opt for prevention methods instead. Anti-seizure medications are thought to reduce the occurrence of migraines by calming inflamed blood vessels in the brain, which may lead to migraine pain. However, none of these medications is a cure for migraines.
Topamax
Topamax (topiramate) is an anti-seizure drug that may help eliminate migraines in some individuals. To prevent these headaches, the drug is typically taken daily, unlike pain medications, which are taken at the first sign of pain. The medication is available in tablet or capsule form and by prescription only. Serious side effects include rapid heartbeat, chest pain, difficulty breathing, intense back or side pain and bloody or cloudy urine. In addition, serious mental or behavioral changes can occur, causing depression, thoughts of suicide or aggressive behavior.
Depakote
Depakote (valproic acid) is an anti-seizure medication used alone or together with other medicines to control certain types of seizures in epileptics. Additionally, Depakote is used to treat bipolar disorder and chronic migraine headaches. The drug is available by prescription only in various forms, including capsule, tablet and syrup. Serious side effects include damage to the liver or pancreas, according to Medline Plus.
Neurontin
Neurontin (gabapentin) is an anti-seizure medication used by epileptics and those with postherpetic neuralgia, pain associated with the shingles virus. As with other anti-seizure medications, the drug works by decreasing excitement in the brain that causes seizures in epileptics and migraines in those with chronic migraine conditions. Serious side effects associated with the use of Neurontin include allergic reactions, which may be evident when itching, swelling or rashes occur on the body. Other signs include swelling of the face, throat, lips, tongue or eyes and trouble swallowing or breathing. Hoarseness or seizures are also serious reactions that require immediate medical attention.
