Which medicines and supplements can interact with Testosterone therapy?

Share a complete medication list before starting Testosterone therapy. Include prescription drugs, over-the-counter products, vitamins, herbal products, and any hormones or bodybuilding supplements. Your physician and pharmacist need this information to check for interactions and decide what monitoring is needed.

Testosterone can affect how blood thinners such as warfarin work. Extra blood tests or a dose change may be needed. It can also change blood sugar control, which may affect insulin or other diabetes treatment. Using testosterone with corticosteroids can increase fluid retention in some people. Do not make these medication changes yourself.

Tell your physician about any other testosterone products, anabolic steroids, or products sold as testosterone boosters. Combining them can increase exposure and risks. Supplements may have unclear ingredients or amounts, so bring the label or a photo of it to your visit.

Keep your medication list current throughout treatment. Ask before starting a new prescription or supplement, even if it seems unrelated. Your physician may also adjust the timing of safety checks when another medicine changes.
