What It Is and How It Works
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the blood vessels in the penis, which allows increased blood flow during sexual arousal. This process helps achieve and maintain an erection. It is important to note that sildenafil does not increase sexual desire but facilitates an erection in the presence of sexual stimulation.
Indications / Uses
The primary approved use of sildenafil is for the treatment of erectile dysfunction. It may also be prescribed for pulmonary arterial hypertension under specific brand names. While sildenafil is effective for many individuals, its use may be contraindicated in certain conditions or when taking specific medications.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in tablet form, with common dosages being 25 mg, 50 mg, and 100 mg. However, discussing a 200 mg dosage is less typical and may not be commonly prescribed due to potential increased risk of side effects. Factors such as age, liver and kidney function, and other medications taken concurrently can influence dosing considerations. Patients need to follow the prescription and guidance provided by their healthcare provider.
How to Take It Correctly Step-by-Step
For optimal effectiveness, sildenafil should be taken approximately 30-60 minutes before sexual activity. It can be taken with or without food, although high-fat meals may delay its onset of action. Individuals should not take more than one dose per day. In cases of a missed dose for conditions other than ED, follow the healthcare provider\’s instructions. Store sildenafil at room temperature, away from excess heat and moisture.
