who should not use viagra for erectile dysfunctionSildenafil is a common drug used for treating erectile dysfunction in men. It is commonly known by its brand name, Viagra. The drug increases blood flow to the reproductive system of men thereby making it easy and possible to gain an erection and maintain it for long period of time, whenever there is sexual stimulation.

Eye problems

One of the serious side effects of Viagra is a sudden loss of vision. This is common in people with high cholesterol, heavy smokers, people with problems in the retina and those who are older than 50 years. The drug decreases blood flow to the eyes for a certain period of time. Thus, people with above conditions should not consume Viagra so as to avoid vision loss. Still, there is no concrete proof to determine whether the drug is the actual cause of vision loss.

Medical conditions related to intercourse

If you are medically advised against having an intercourse, you should not use Viagra. The drug will inhibit the body changes that take place during intercourse. Thus, do not use the pill if you are restricted from having sex, due to any medical condition.

What are the drugs that should not be taken while administering Viagra?

In general, if you are consuming any life-saving drug, do not use Viagra, without consulting your doctor. Viagra interacts with many other drugs and can cause harmful effects. Here is the list of drugs that commonly interact with Viagra.

  1. Antibiotics like telithromycin, clarithromycin, and erythromycin
  2. Antifungal medicines
  3. Medicines used for treating HIV or AIDS like ritonavr, atazanavir and others
  4. Drugs for high blood pressure
  5. Drugs for prostate disorders
  6. Other erectile dysfunction drugs
  7. Painkillers like aspirin, tramadol, and others
  8. Vitamin D3
  9. Diabetes drugs like metformin

Viagra should not be taken by men who take alcohol in the excess measure. Alcohol reduces the blood pressure and so does the drug. When consumed together, blood pressure drops down significantly and can cause symptoms like fainting, heart palpitation, dizziness and others. At least, do not drink while using the drug.

Grapefruit and products of grapefruit can also reduce the effects of the drug in the body. It is just a moderate interaction and you can avoid eating the fruit to reduce the problem.

Viagra should be taken with caution. If you have any life-threatening medical condition, talk to your doctor and give the list of medical conditions you are suffering from along with the medical history and the drugs that are being administered. Your doctor will determine whether the drug is right for you or not. Moreover, adding more doses will not increase the effectiveness of the drug. It will cause overdose and create more problems and side effects. Stick to the directions and doses indicated by your doctor.
