Sildenafil 50mg Sublingual Tablets
- A sildenafil treatment option for erectile dysfunction available through provider-guided sexual-health care.
- Treatment requires review by a licensed healthcare provider and a prescription when clinically appropriate.
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction. It works by increasing blood flow to the penis during sexual stimulation, helping support an erection when sexual stimulation is present.
Use this medication exactly as prescribed by your healthcare provider. Because this product is a sublingual formulation, follow the specific administration instructions provided with your prescription and dispensing pharmacy rather than applying instructions for a conventional sildenafil tablet.
Common sildenafil side effects include headache, flushing, indigestion, nasal congestion, nausea, and visual disturbances. Sildenafil also has important cardiovascular and medication-interaction warnings that should be reviewed before treatment.
Your healthcare provider determines whether sildenafil is appropriate for you after considering your health history, current medications, cardiovascular factors, and other individual circumstances.
