What is Acetaminophen-Caffeine-Isometheptene Mucate used for?
Acetaminophen-Caffeine-Isometheptene Mucate is a combination medication used to relieve tension and migraine headaches. Headache pain can sometimes be caused by widened blood vessels in the head. Isometheptene works by narrowing these widened blood vessels. Caffeine also works by narrowing widened blood vessels in the head, and is a mild stimulant. Acetaminophen relieves mild to moderate pain from various causes, including headache.
How should I take Acetaminophen-Caffeine-Isometheptene Mucate?
Take this medication by mouth with or without food as directed by your doctor. The dosage is based on your medical condition and response to treatment.
For migraine headache, take this medication at the first sign of a migraine as directed by your doctor, usually 1 to 2 tablets first, followed by 1 tablet every hour until the headache is relieved. Do not take more than 5 tablets in a 12-hour period.
For tension headache, take as directed by your doctor, usually every 4 hours as needed. Do not take more than 8 tablets in a 24-hour period.
Pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.
If you are using drugs for migraine attacks on 10 or more days each month, the drugs may actually make your headaches worse (medication overuse headache). Do not use medications more often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if your headaches get worse.
