Tadalafil is a phosphodiesterase-5 (PDE-5) inhibitor used to treat erectile dysfunction in men.

• Tadalafil’s most common side effects include headache, upset stomach, nausea, dizziness,  back pain, nasal congestion, and warmth or redness in your face, neck, arms or upper chest.
• Contact your medical provider if these side effects bother you or do not go away.
• Seek emergency medical care if you have a painful erection or an erection that lasts longer than 4 hours. This may happen even when you are not having sex. If this is not treated right away, it may lead to lasting sex problems and you may not regain normal organ function.
