headache
"I was prescribed fioricet for migraines. Not only didn't it help the migraine, fioricet caused my heart rate to skyrocket (due to the amount of caffeine it contains) and gave me an absolutely WICKED rebound headache the next day. In fact, the rebound headache was worse than the original migraine. Needless to say, I threw the rest of the pills down the toilet.
Fioricet is also EXTREMELY addicting if taken more than 3 times per month. Astonishingly, I was prescribed 1 to 2 tablets EVERY 8 hours for migraines with NO WARNING whatsoever from my doctor about how addicting this medication is. Thank God it didn't work for me or else I'd be a fioricet addict facing withdrawal whenever the drug isn't taken. It should be taken off the market"
