Where to buy Viagra

You can buy Viagra at your local pharmacy with a prescription or save a lot of money and buy the drug at an online pharmacy with a big discount for up to 50%. Remember to clarify the dosage of Viagra with your doctor if you are going to buy the drug in the online drugstore, because overdose of the drug can lead to severe side effects.

How to take Viagra

Each tablet of Viagra contains 25 mg, 50 mg, or 100 mg of sildenafil. This active ingredient inhibits the specific phosphodiesterase enzyme, which weakens the smooth muscles of the blood vessels of the penis, increases their blood-filling and creating an erection.

However, erection appears only in the presence of sexual stimulation. The drug begins to act within 30 minutes after intake, and the duration of its action lasts for five hours. Viagra should be taken orally, regardless of the food intake. When taken on an empty stomach, the rate of absorption of the active substance of Viagra is much higher.

Viagra with alcohol and fatty foods

The consumption of fatty foods or alcoholic beverages can significantly reduce in time the onset of action of Viagra and even reduce the effectiveness of the drug since its absorption slows down.

Furthermore, the simultaneous use of alcohol in significant quantities with Viagra tablets negatively affects the condition of the liver and blood vessels, which can lead to a violation of blood pressure, headaches and pain in the heart.

Dosage

The standard dosage is 50 mg, but it can be increased to 100 mg. The maximum daily dosage of Viagra is 100 mg.

If the patient has heart or vascular disease, it is recommended to reduce the dosage of the drug to 25 mg. If the patient has cirrhosis, the dosage should also be equal to 25 mg.

Side effects

Viagra is well tolerated and doesn’t cause any side effects in most patients. If any side effects occur, they are usually mild and pass quickly after a few hours.

Some of the main side effects are headaches, myalgia, changes in visual perception (blurred vision, changes in color perception), nasal congestion, heartburn, stomach disorders, dizziness, and allergic reactions.
