Migraine headaches generally represent no significant threat to your overall health. However, they can be chronic, recurrent, frustrating, and they may interfere with your day-to-day life.

Stroke is an extremely rare complication from severe migraines. This risk may be due to prolonged narrowing of the blood vessels, limiting blood flow to parts of the brain for an extended period of time.

Call 911 if:

• You have unusual symptoms not experienced with a migraine before, like speech or vision problems, loss of balance, or difficulty moving a limb
• You are experiencing "the worst headache of your life"

Call your doctor immediately if:

• Your headache pattern or intensity is different
• Your headache gets worse when you lie down

Also, call your doctor if:

• Previously effective treatments no longer help
• Side effects from medication occurs (irregular heartbeat, pale or blue skin, extreme sleepiness, persistent cough, depression, fatigue, nausea, vomiting, diarrhea, constipation, stomach pain, cramps, dry mouth, extreme thirst, or others)
• You are likely to become pregnant -- some medications should not be taken when pregnant
