Side Effects of Viagra

Viagra Side EffectsNumerous researches show that generic Viagra is an effective and safe medicine for erectile dysfunction treatment with minimal adverse effects. In some countries is sold over the counter, in other ones a prescription is required for its purchasing. In fact, the requirement of prescription is a precautionary measure, because, despite its safety, Sildenafil (an active component of Viagra) has certain side effects and contraindications. The most common viagra side effects include the following ones:

• A headache or dizziness. Though nasty, they are not dangerous for health and usually stop after the effect of Viagra is over (in 4-6 hours after taking of pill).
• Temporary blurred vision or even loss of vision. This is caused by the impact of Sildenafil on the eye nerve. If this effect lasts more than 4 hours, consult a doctor.
• Upset stomach, diarrhea or stomach ache is quite rare and depends on personal sensitivity to the components.
• Irregular heartbeat or sudden changes in blood pressure. This is more common for the patient that had heart problems before. If you have ever had any heart or cardiovascular diseases, you’d better consult a health specialist before taking sildenafil.
• An allergic reaction is also very rare and is caused primarily by idiocracy of Sildenafil. In the case of allergic reaction take the antihistamine drug, and if the symptoms are severe, call for emergency medical help.
• Priapism or persistent erection of the penis. This occurs very, very rarely, but if this happens, it’s recommended to call for emergency help and avoid taking the drug in future. Priapism is a too long (more than 4 hours) painful erection.

Side effects of Viagra can prevent some men from purchasing the drug. However, one should remember that in most cases Viagra is well tolerated. If a man has no serious health problem, he is not likely to suffer from any adverse effects.

At the same time, Sildenafil has some contraindications that should be taken into account. They are not numerous, but their ignoring can have undesirable consequences. So, learn the information about contraindications carefully, before ordering Viagra.

• Sildenafil must not be taken with any nitrate-containing drugs because it is involved in biochemical processes related to nitrogen oxide production. Simultaneous use of Viagra and nitrates can cause a critical drop in blood pressure. That is why it is usually contraindicated in patients suffering from cardiovascular diseases.
• Viagra should not be combined with alcohol drinks and fatty meals. Alcohol brings to naught the effectiveness of Sildenafil and can cause a reverse effect in the form of erection weakening.
• Men with chronic diseases should be very cautious when taking Viagra. For example, diabetes can be a contraindication for Sildenafil taking. In any case, if you suffer from any serious disease, try at least to consult a doctor before buying Viagra. Maybe a specialist will prescribe you a smaller dosage of the drug.
