I'm taking tramadol activis (50 mg) for a toothache. The tramadol is left over from a prescription for pain after a bike accident, and yes, I know one isn't supposed to save and self-diagnose, medicate, etc. But I am doing so in order to get some relief. Visited dentist today and he gave me prescrip. for penicillin as infection is his only guess since the tooth looks fine. My question re: tramadol is: what is a usual dose? I recall originally being prescribed two pills, four times a day. But I'm taking just one, and waiting approx. 6 hrs. before taking a second one. Is normal dose 50 mg four times a day?
