Is it safe to take 3 acetaminophen with codeine at one time?

Tough question: You could.Especially for very short term of pain control and they are from the lower dosage. On the other hand the side effects (constipation, ....)is dose related and if you take it for longer time you will develop tolerance to it where higher and higher doses will be needed.You need to let your doctor know. He may give you s.Th. Else or add acupuncture, self hypnoses or other meds that are safer.
