Would tagamet (cimetidine) have the potential to effect a testosterone test the same day? In other. Words temporarily lower it for the test? Thanks so much

Tagamet (cimetidine) only. Affects testosterone at very high doses over a prolonged period of time. It is unlikely that one dose could lower the level enough to make the test abnormal. If there's a concern, stop the tagamet (cimetidine) and repeat the test at a later date. Talk w/your doctor.
