Drug Interaction Report

Somatropin may reduce the blood levels and effects of sildenafil. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Let your doctor know if sildenafil becomes less effective or is no longer controlling your symptoms. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
