Viagra: effects and duration

In order to get an erection, your heart, blood vessels, hormones, nerves, and even your mood must be coordinated.

An erect penis fills with blood and contains up to 8 times more blood than a flaccid penis. In this sense, when the blood trapped in the penis is released, the erection stops, and the blood flow returns to normal. 

The effect of 비아그라 구입 usually lasts for an average of 4 hours and may vary from person to person. This will depend on the dosage, therefore, your metabolism, and other external factors such as age, diet, and general health conditions. But that doesn't mean you'll have an erection that lasts 4 hours! In fact, this means that during these 4 hours, Viagra will be acting as a facilitator of your erection.

Doctors recommend taking Viagra outside of mealtimes to start the effects on erection as soon as possible.  

Viagra side effects

If you are between the ages of 18 and 60, are not taking any other medications or have any other health problems, the most likely side effects are:

Transient drop in blood pressure, nasal congestion or runny nose, dyspepsia, hot flashes, headache, indigestion, and muscle or back pain.

Other rarer side effects include vision disturbances, insomnia, and nosebleeds. Very rarely, they have reported a sudden hearing loss. 

A very rare side effect of Viagra is decreased blood flow to the optic nerve, causing sudden loss of vision: this risk is greater in people over 50 or with diabetes, heart disease, high blood pressure, high cholesterol, who smoke, or who already have certain vision problems.

Rarely, viagra can cause other side effects or lead to painful erections that last longer than four hours. See your doctor immediately if this happens.

비아그라 may interact with some medications, including certain antibiotics and antifungals, herbal medicines, drugs that fight HIV, and drugs used to treat high blood pressure or prostate problems.

In general, the elderly, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures), or users of other medications are at a higher risk of developing more side effects. 

Caution: This list may not describe all possible side effects. Therefore, if you experience any side effects, discontinue treatment and consult a doctor to adjust the dosage to your problem. 

Is viagra dangerous?

비아그라 구매 is not dangerous, as long as it is administered after consultation with a urologist and purchased under prescription at a pharmacy. This makes it possible to limit the risks and ensure regular monitoring in order to adapt the dosage and treatment and ensure the origin of the medicines.
