What is sildenafil?

Sildenafil is the active ingredient in a well-known medication for erectile dysfunction. It belongs to a class of medicines called PDE5 inhibitors and is taken as needed before activity. Because it can interact with certain conditions and medications (for example, nitrates), it is available by prescription only, and a licensed physician determines whether it is appropriate and safe for you.

Who commonly uses sildenafil?

Doctors On Site physicians commonly assess patients seen through our programs, including:

Erectile dysfunction Difficulty achieving or maintaining an erection Patients seeking a physician-assessed treatment option Patients who prefer an as-needed oral medication

How does sildenafil work?

Sildenafil increases blood flow to the penis in response to sexual stimulation, which can help achieve and maintain an erection. It is taken as needed, not daily. Because of possible interactions and contraindications, a physician reviews your history before prescribing.

Who may qualify?

  • Adults seeking assessment for erectile dysfunction
  • Patients willing to complete a clinical assessment with a licensed physician
  • Those without contraindications identified during the assessment
  • Patients who can commit to appropriate follow-up
