Background:

• Erectile dysfunction (ED) is a common condition affecting many men.
• Oral pharmacotherapies are a primary treatment modality for ED.
• Sildenafil is a widely prescribed medication for ED.

Purpose of the Study:

• To highlight critical patient instructions and contraindications for sildenafil use.

Main Methods:

• Review of clinical data and prescribing information for sildenafil.
• Analysis of common side effects and drug interactions.
• Identification of patient populations for whom sildenafil is contraindicated.

Main Results:

• Sildenafil is the most effective oral therapy for ED.
• Common side effects include flushing, headaches, dyspepsia, and visual disturbances.
• Fatal hypotension can occur when combined with nitrates; co-administration is contraindicated.
• Sildenafil is not recommended for patients with low cardiac output, heart failure regimens, or acute coronary ischemia.

Conclusions:

• Sildenafil offers significant efficacy for ED treatment.
• Clear patient counseling on administration and contraindications, particularly with nitrates, is essential for safe use.
• Careful patient selection is crucial to minimize adverse events.
