What are the side effects of long-term consumption of sildenafil

Long term use of sildenafil may cause side effects such as headaches, facial flushing, indigestion, visual abnormalities, and cardiovascular risk. Sildenafil is mainly used to treat erectile dysfunction and should be strictly used according to medical advice to avoid self adjustment of dosage or long-term dependence.

1. Headache

Sildenafil may cause vasodilation, leading to changes in head vascular pressure, and some users may experience mild to moderate headaches. Headaches are usually brief and self relieving. If they persist or worsen, timely medical evaluation should be sought. Avoid combining with other vasodilators, hypertensive patients should be cautious.

2. Facial flushing

The dilating effect of drugs on subcutaneous blood vessels may cause redness and fever of the skin on the face, neck, or chest. This phenomenon often occurs shortly after medication and is a common reaction. Sensitive individuals or those who have consumed alcohol may experience more pronounced symptoms and generally do not require special treatment.

3. Dysdigestion

Sildenafil may affect gastrointestinal smooth muscle function, leading to discomfort, bloating, or acid reflux in the stomach. It is recommended to avoid taking on an empty stomach, as taking it with a high-fat diet may delay the effectiveness of the medication. Individuals with chronic gastrointestinal diseases should be informed in advance if necessary to adjust their medication regimen.

4. Visual abnormalities

A small number of patients may experience blue vision, photosensitivity, or blurred vision, which is related to the inhibitory effect of drugs on retinal phosphodiesterase. The symptoms are mostly transient, but patients with retinopathy or glaucoma have a higher risk and need to use it under ophthalmic monitoring.

5. Cardiovascular risk

Sildenafil may cause blood pressure fluctuations, and its combination with nitrate drugs can lead to severe hypotension. Heart disease patients need to undergo a comprehensive assessment of heart function before medication and avoid strenuous exercise. Sudden chest pain or palpitations should be immediately discontinued and medical attention sought.

Long term use of sildenafil should be regularly monitored for cardiovascular and visual function, and avoid taking it with alcohol or high-fat diets. It is recommended to comprehensively manage erectile dysfunction by improving lifestyle habits such as regular exercise, weight control, and psychological counseling. If there is persistent discomfort during medication, timely follow-up is required. Do not increase the dosage or frequency without authorization. Individuals with underlying diseases need to weigh the benefits and potential risks under the guidance of a doctor.
