Hi doctor,
Does taking sexual stimulant tablet or testosterone booster, prevents finasteride to work full?
Ask the doctor that is providing you sexual stimulants or testosterone boosters before starting or stopping any medication (including finasteride). Generally, what do you mean by a sexual stimulant? Viagra? Or some pill you buy from the back of a men’s magazine? There are many items that could qualify as a sexual stimulant.
Testosterone is an anabolic steroid that is generally illegal to use without the supervision of a prescribing doctor due to many side effects, such as liver damage. It can also cause increased androgenic alopecia (AGA) so if you are taking testosterone (or boosters), clearly that will ‘pull’ in the opposite direction of finasteride on your hair loss, thus defeating the purpose of using finasteride at all.
