Does drinking alcohol effect the depo-provera shot if its already in your system?
A huge variety od medicines are affected by alcohol by the simple fact that the metabolization of many medicines take place in the LIVER. Then, alcohol will begin a slow-down on the effect of the shot – not cut its effect, but the shot will pass by your system faster than it should. Then, the timing you would expect it to be effective will not be true. I just spoke to a pharmacist about the subject, she confirmed to me that MANY CASES like that happen – because after the alcohol ingestion, you cannot determine how long the medicine will stay in your system, then the risk of pregnancy is high.
