"i use darvocet for severe headaches if/when ibuprofen won&#039;t relieve the pain. i can take darvocet and not have to miss work because of the headaches. the only (minor) side effect is a bit of drowsiness, which goes away after i drink my morning tea. the added benefit of the drowsiness is getting additional headache relief by sleeping (if i am at home).  i hope and pray that the fda&#039;s recent recommendation to withdraw it from the market is reconsidered. i would be lost without my darvocet - i use it infrequently, and only out of necessity, but i wouldn&#039;t take any other pain prescription to stop my headache pain. saying that acetaminophin is as effective as darvocet is a joke; tylenol never relieves my pain when taken alone."
