What are the side effects of taking Viagra?

The main ingredient of Viagra is sildenafil citrate, which can enhance the erectile function of patients, thereby improving their erectile function and can be used to alleviate the clinical symptoms of impotence. What are the side effects of taking Viagra? Let's find out together.

1. Headache

Clinical trials have found that about 13% of people experience headaches after taking the drug, and the intensity increases with the dosage.

2. Lowered Blood Pressure

Taking Viagra can lower blood pressure, and heart medications containing nitroglycerin or nitrates also lower blood pressure. Therefore, when Viagra is mixed with these medications, blood pressure may drop significantly, potentially危及 life.

3. Infertility

Long-term use of Viagra as an aphrodisiac may impair fertility. Male reproductive function is related to sperm quality. Long-term use of Viagra can lead to decreased sperm quality, decreased male reproductive function, and even infertility.

4. Induced Prostate Diseases

Men who rely long-term on Viagra may damage their prostate function because using this drug can normalize penile erections and extend sexual activity duration. However, prolonged penile congestion and erections can easily damage the corpus cavernosum and even allow bacterial invasion during congestion. Thus, there is a high likelihood of prostate dysfunction, potentially leading to prostate pathology.

5. Dizziness and Blurred Vision

Taking Viagra can cause blood pressure to drop. For some patients with hypertension or hypotension, or those with similar conditions, it can cause dizziness. 3% of users may experience transient blurred vision or even hallucinations. Therefore, US officials prohibit pilots from flying within 6 hours of taking Viagra to avoid accidents.

6. Persistent Impotence

Men with urethritis and leukemia may experience prolonged erections after taking Viagra, damaging the muscular tissue of the genital area and even worsening impotence. If an erection lasts more than 4 hours, immediate medical attention is required.

Above are the side effects of Viagra. I hope this information is helpful. All medications have side effects, so attention must be paid to dosage.
