Darvocet A500 - What are the exact side effects of this drug?

Nausea, drowsiness, itching, feeling light headed, and rebound headaches sometimes. These are a few of them. Definitely eat before taking this medicine as it will lessen the side effects and do NOT drink on this or it will really dramatically increase the effect of the alcohol. You should use caution when driving, using machinery or any task which requires coordination or sobriety. You shouldn't get a rebound headache if you take them as prescribed and don't up the dose.
