"Viagra" works in response to stimulation - without physical impact on the penis, it will not work.

Due to the relaxation of blood vessels, Viagra helps with pulmonary hypertension - high pressure in the vessels supplying the lungs. It increases blood flow to the lungs and reduces the workload on the heart. In this case, both men and women can drink it.

The most common side effects are headache and facial flushing.
The most common side effects of Viagra are usually mild and short-lived. As a rule, they do not last more than five hours. On average, they happen to one person in a hundred. It can be:

redness of the face and a feeling of heat;
headache or dizziness;
indigestion, nausea or heartburn;
vision problems: clouding or blue tint in the eyes, photosensitivity;
nasal congestion or runny nose;
backache.
In rare cases, more serious side effects may occur, such as:

loss of hearing or vision. In 2007, the Cambridge Journal of Laryngology and Otology reported that a 44-year-old man became deaf in both ears after taking Viagra 50 mg for a half month. A larger 2010 study found a similar link but failed to prove it;
after taking Viagra, ischemic optic neuropathy can develop - a sudden and permanent loss of vision due to the cessation of blood flow to the optic nerve. This is more common in men with high blood pressure, heart disease, or diabetes. Scientists have not yet proven a direct connection, but before taking the drug, it is better to consult an ophthalmologist. Men with retinitis pigmentosa, an inherited eye disease that leads to blindness, should also check with their doctor before taking Viagra;
Priapism is a rare condition in which an erection does not last longer than four hours. This can cause severe pain and damage to the penis, so it is best to see a doctor without delay.
