10 Side Effects of Viagra Revealed

1. Headache

Clinical trials have found that approximately 13% of people experience headache symptoms after taking the medication, and the greater the dose, the more severe the pain.

2. Blurred vision

Another study showed that about 3% of people who take the drug may experience temporary blurred vision, and some may even experience blue light hallucinations.

3. Dizziness

Taking Viagra may cause a sudden drop in blood pressure, just like taking drugs such as nitroglycerin at the same time, and may also cause dizziness or even fainting.

4. Abnormal erection

It will damage the genital muscle tissue and may even aggravate impotence.

5. Covering up cardiovascular disease

Erectile dysfunction may be a precursor to heart disease, diabetes or cancer, and taking the drug may mask the real condition.

6. Lower blood pressure

Viagra may cause a decrease in blood pressure, and heart disease medications containing glyceryl trinitrate or nitrates can also lower blood pressure. Therefore, if Viagra is mixed with these drugs, blood pressure will drop significantly, which may sometimes be life-threatening.

7. Permanent impotence

Long-term use of Viagra can cause the body to become drug-dependent and may even lead to permanent impotence.

8. Glaucoma

Ophthalmologists say that taking Viagra can cause a drop in blood pressure and a higher risk of glaucoma. 3% to 5% of people may develop acute glaucoma, which can cause blindness overnight. Even if cured, it is difficult to restore original vision.

9. Temporary hearing loss

According to the FDA, Viagra can cause deafness, and about one-third of patients suffer from temporary hearing loss.

10. Infertility

Some American experts believe that if young people use Viagra, it is likely to affect their reproductive ability.
