Quick Facts

• Sildenafil is primarily used to treat erectile dysfunction and pulmonary arterial hypertension.
• It works by increasing blood flow to certain areas of the body, particularly the penis.
• Common forms include oral tablets, with strengths typically ranging up to 100mg.
• Effects can typically be noticed within 30-60 minutes, and may last for up to 4 hours.
• Common side effects include headaches, flushing, and indigestion.

• Seek urgent medical help if experiencing chest pain, vision changes, or an erection lasting longer than 4 hours.

What It Is and How It Works

Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It facilitates the relaxation of blood vessels in the penis, allowing increased blood flow, which assists in achieving and maintaining an erection when sexually stimulated. For pulmonary arterial hypertension, it works by relaxing blood vessels in the lungs, reducing the strain on the heart and improving symptoms.

Indications / Uses

Sildenafil is primarily indicated for the treatment of erectile dysfunction, where it assists in producing and maintaining erections adequate for sexual activity. It is also prescribed for adults with pulmonary arterial hypertension to improve exercise capacity and delay clinical worsening. While there are discussions about off-label uses, such as for Raynaud’s phenomenon, these uses should only be considered under direct medical supervision.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available mainly in oral tablet forms, commonly in doses of 25mg, 50mg, and 100mg. The typical starting dose for ED is 50mg, taken as needed approximately one hour before sexual activity, but can be adjusted based on effectiveness and tolerance. Dosing may vary significantly based on individual factors such as age, liver and kidney function, and other medications being taken. For PAH, dosing schedules differ and require careful medical guidance.

How to Take It Correctly Step-by-Step

• Take sildenafil as prescribed by your healthcare provider.
• It is usually taken one hour before sexual activity but can be taken between 30 minutes to 4 hours prior.
• Do not take more than once per day.
• Swallow the tablet whole with water, with or without food. Note that high-fat meals can delay performance.
• If a dose is missed in the context of PAH treatment, take it as soon as you remember unless it’s close to the next dose.
• Store sildenafil at room temperature, away from moisture and heat.
