Viagra-pills that are aimed at natural sexual arousal in men. The drug is usually used to eliminate erectile dysfunction. The active substance of sildenafil tablets causes the increased blood circulation in the genital area, resulting in increased and prolonged erections, as well as orgasmic experiences. Today in pharmacies under this name there are dietary Supplements with natural components, drugs to enhance libido, and other means.
What is Viagra?
History of creation
The sale of "Viagra" for men appeared in 1998 and was intended for the treatment of problems related to potency. However, the drug was developed for completely different purposes. Initially, it was proposed to use it for patients with hypertension. But as it turned out during the study, it does not reduce the pressure, but men noted that after taking the pills they had a long erection.
The Action Of Viagra
How does Viagra work? The use of these tablets for men increases blood circulation in the penis area. This is the main secret of the drug's effectiveness since it is the violation of blood flow to the organ that can cause the absence of an erection.
It is believed that after taking the pill, an erection will last a very long time. However, this is not entirely true. The fact is that the action of "Viagra" begins only in the presence of sexual arousal in a man. If earlier he had arousal, but the erection was absent or was insignificant, then after using the drug, the penis reaches its natural size and the hardness necessary for sexual intercourse. Thanks to the pills, the sexual act is prolonged (how long should sex last), but after ejaculation, the erection disappears and can only occur when the man is re-aroused. The duration of "Viagra" is about 4 hours, which will be enough for several full-fledged sexual acts.
The effect of the generic Viagra
Some "insurance" for a man is that the pill begins to act only under the condition of natural arousal, that is, it can not start working at an inconvenient moment for this. Also, a woman will not be able to suspect a man from using the drug.
Indications for use
The maximum daily dose of the drug for a healthy man is 100 mg. Start using tablets with 50 mg. For certain groups of patients (men over 65 years of age, patients with kidney, liver, or cardiovascular diseases), this dosage is reduced to 25 mg. How to take Viagra correctly can tell the doctor after a detailed examination of the man. Do not exceed the doctor's recommended dose.
Similarly to all medications, Viagra has its contraindications to use. All of them are due to the possibility of side effects of the drug in the presence of certain diseases. Contraindications of "Generic Viagra" are:
- Hypersensitivity to the components that make up Viagra.
- Reception of any products that contain nitrates. According to research, their simultaneous use can lead to a sharp decrease in blood pressure in men.
- Severe abnormalities in liver function.
Stages of liver damage
Medications with PDE-5 inhibitors. The ban on their simultaneous use is due to the lack of clinical trials and the inability to predict the effect of tablets in this case.
Under 18 years of age.
According to the instructions, there are some conditions in which taking pills is allowed only under the supervision of doctors and with extreme caution:
Features of the anatomy of the penis, which can be both congenital and acquired, in which blood circulation in the penis may be impaired. In this situation, the effect of the drug can not be predicted.
Pathologies associated with priapism (involuntary erection for several hours without prior sexual stimulation).
- Genetic determination of retinol.
- Exacerbation of peptic ulcer disease.
Pathology of the heart and other disorders in the work of the organ that was observed in men in the past. Men's "Viagra" (cheaply price) and other stimulants of arousal are not recommended for those who have had a heart attack, stroke, or angina.
Even a single dose of the drug is possible only after consulting a doctor. The above list of contraindications is far from complete. Side effects of Viagra may occur when used simultaneously with other medications.
Indications for use, contraindications, and methods of using Viagra and its analogs are very similar. You don't need to rely on reviews from other people who have taken them, as this can lead to negative consequences. Before you start using a particular drug, you should consult your doctor.
The possibility of side effects is affected by the dosage of the drug. Investigating the possible harm of "Viagra", doctors have identified several side effects:
- The redness of the skin is associated with increased blood circulation.
- Visual impairment (hypersensitivity to bright light, blurred vision, etc.).
- Increased heart rate.
- Nasal congestion.
The normal state of the heart and atrial fibrillation
Arrhythmia – any violation of the regularity or frequency of the normal heart rate, as well as the electrical conductivity of the heart:
- A sharp drop in blood pressure.
If you use "Viagra" for potency in high doses, you may experience unpleasant symptoms:
- From the cardiovascular system: redness of the skin, headache, dizziness, nosebleeds, tachycardia.
- From the digestive system: digestive disorders.
