Contraindications

 

Viagra ® (sildenafil citrate) is contraindicated in patients who are taking organic nitrates in any form at any time.

 

Consistent with its known effects on the nitric oxide/cGMP pathway, Viagra ® was shown to potentiate the hypotensive effects of nitrates and its administration to patients who are concurrently using organic nitrates in any form is therefore contraindicated.

 

Viagra ® is indicated for the treatment of Erectile Dysfunction.
