Since it is brief, the vision loss of ocular migraines is not usually treated. But you may need relief for the headache that accompanies or follows it.
The primary treatment for ocular migraines is to reduce exposure to triggers. Calcium-channel blockers are the main drug treatment for ocular migraines. They work by relaxing the blood vessels. One example is Cardene, which can be given as a pill or as a tab you put under the tongue.
Beta-blockers usually treat high blood pressure and heart disease. It's not clear how they help prevent migraines. But it may be because they improve blood flow. Some that work for these headaches include:
Antidepressants. These medications affect the level of the brain chemical serotonin, which may be linked to migraines. Some of them, such as amitriptyline (Elavil) and venlafaxine (Effexor), can help keep the headaches away. Other kinds may work, too.
Triptans for menstrual-related migraines. These drugs treat migraines when they’re already happening, but one -- frovatriptan (Frova) -- can prevent migraines that women get because of their menstrual cycle. The medicine affects serotonin levels and may also relieve pain in other ways.
Botulinum toxin (Botox). Often used to treat wrinkles, it also helps some people who get migraines at least 15 days per month, called chronic migraines. It’s for people who have long-term migraine headaches, with the attack lasting 4 hours every day or longer. Doctors think Botox may keep the brain from giving off chemicals that the body uses to send pain signals.
