Drugs for erectile dysfunction

There are various options for the treatment of erectile dysfunction in men. The differences between methods can be significant: oral use, injections, mechanical treatment with devices and surgical treatment.

The most commonly used treatment is oral medicine intake. It is safe, effective and comfortable for a man.

The medicines used for the treatment of male impotence are known: Viagra, Levitra, Strendra and Cialis. The actions and side effects of these medicines are practically the same. The time of action differs between Viagra (4 hours), Levitra (4-5 hours), Stendra (6 hours) and Cialis (up to 36 hours).

The price of the medicines can limit the choice for lots of men. Most popular drugs Viagra and Cialis cost much higher than other drugs.

Approximately 70 % of all men with impotence prefer oral treatment for their condition. After taking any of the approved oral medicines they report good quality of erections, ability to have normal sexual activity and natural restoration of the sexual life.

Sildenafil (Viagra) is often the first drug a man uses. It has been on the market for the longest time and is known as very effective. Then comes Cialis with its potency to last in the body for about 36 hours. Levitra and Stendra may have fewer side effects, but they are not so popular with men.

Tadalafil (Cialis), Sildenafil (Viagra), Avanafil (Stendra) and Vardenafil (Levitra) all improve blood supply to the penis. In combination with sexual stimulation, the medicines produce erection functional for starting and completing sexual intercourse. All the medicines are recommended for on-demand basis. Between the doses 24 hours should pass.

One medicine Cialis is approved for use daily in a dose of 2.5 or 5 mg. It also helps relieve urinary problems associated with enlarged prostate.

One of the challenges for a man to find the best oral treatment for impotence is not visiting a doctor. It is the cost of the medicines. The high price can limit the amount of the medicine which a man can afford per month. This makes sexual activity not as regular as a man wishes. Usually health insurance does not cover the number of pills a man needs in one month.

Buying oral impotence medicines online from online pharmacies can reduce the amount of money spent on the medicines each month. A man can compare prices, find the best offers and discounts, and try promo packs and other options.

All oral drugs to produce an erection sufficient for intercourse work practically the same way. They help improve the blood flow directly to the penis. Still some men respond to one medicine better than to the other. By knowing this a man can switch from one medicine to the other. Promo packs offered in online pharmacies are made to help men in identifying the best medicine for them. And health experts often recommend trying several medicines before opting for other treatment methods.

Viagra ocular side effects

Viagra may cause serious vision side effects such as retinal dysfunction or complete vision loss. Other most common, but less serious ocular side effects are: blurred vision, high light sensitivity.

Viagra clinical trials demonstrated that ocular side effects happen rarely and like other side effects are dose – related. Higher doses produce more serious side effects. In clinical trials about 3 % of men taking doses of 25-50 mg of Viagra experienced blurred vision, about 11 % of men taking 100 mg doses, and about 50 % of men taking 200 mg of Viagra have vision changes. In patients using more than 600 mg vision changes were detected in practically 100% of cases. Vision changes are explained by the property of Viagra to mildly affect the enzyme PDE6. Larger doses increase the blood concentration of the medication and increase the risk of ocular side effects.
