Introduction

In general, Viagra refers to sildenafil citrate tablets, and its side effects include headache, indigestion, decreased vision and hearing, hypotension, and priapism. It is recommended to strictly follow the prescribed dosage as directed by a physician in daily use; do not adjust the dosage on your own. If severe discomfort or adverse reactions occur after taking the medication, seek medical attention immediately.

Generally, Viagra refers to sildenafil citrate tablets, and its side effects include headache, indigestion, hearing loss, hypotension, and priapism. Detailed analysis is as follows:

1. Headache

Sildenafil citrate tablets cause vasodilation. When the drug acts on the blood vessels in the head, it may lead to excessive dilation of the head blood vessels and slight changes in intracranial pressure. Usually, this change stimulates surrounding nerve endings, resulting in headache symptoms.

2. Indigestion

Sildenafil citrate tablets may affect the normal peristalsis and secretion of digestive fluids in the gastrointestinal tract, interfere with the nervous regulation of the gastrointestinal system, slow down gastrointestinal peristalsis, and prolong the retention time of food in the stomach. This can lead to indigestion, causing symptoms such as nausea, vomiting, bloating, and diarrhea.

3. Hearing Loss

This medication may affect the blood circulation of the inner ear, causing insufficient blood supply to the inner ear tissue and resulting in damage to the auditory nerve. Additionally, the drug may also affect the metabolism and ion balance of the inner ear. This can lead to symptoms such as hearing loss and tinnitus.

4. Hypotension

Sildenafil citrate tablets have a vasodilatory effect. When the drug acts on the systemic blood vessels, it reduces vascular resistance and lowers blood pressure. Especially when used in combination with nitrates, this hypotensive effect becomes more pronounced. Patients may experience symptoms such as dizziness, fatigue, and visual darkening; severe cases may lead to syncope and even endanger life.

5. Priapism

Under normal circumstances, penile erection returns to normal after sexual stimulation ends. However, sildenafil citrate tablets may cause persistent congestion of the corpora cavernosa and poor outflow of blood. If the erection lasts more than four hours, priapism may develop.

It is recommended to strictly follow the prescribed dosage by a physician in daily life; do not adjust the dosage on your own. If severe discomfort or abnormal reactions occur after taking the medication, seek immediate medical attention.
