Tadalafil

Tadalafil is used for:

Treating erectile dysfunction in men (eg, impotence) and other conditions as determined by your doctor.

Tadalafil is a phosphodiesterase type 5 inhibitor. It works by helping the blood flow into the penis to achieve and maintain an erection during sexual stimulation.

Do NOT use Tadalafil if:

• you are allergic to any ingredient in Tadalafil
• you have been told by your health care provider not to participate in sexual activity because of certain heart or health problems
• you are taking or using any type of nitroglycerin (eg, under the tongue, capsule, tablet, spray, patch, ointment, paste) or other nitrates (eg, isosorbide), or recreational drugs ("poppers") containing amyl or butyl nitrate

Contact your doctor or health care provider right away if any of these apply to you.
