Viagra Side Effects
Viagra is a prescription medicine that is used for treatment of impotence in men. Its stimulating effect is particularly obvious during sexual arousal, as it exerts direct influence on the process of erection. The drug is also known as Sildenafil. It is often termed a 'selective' drug, since its action is concentrated on one particular area of the body. Although in some cases the medicine has proven to boost sexuality enormously, its effect is temporary, and it will not clear the cause of erectile dysfunction.
Although research has confirmed the drug's sufficiency in boosting erection, it is not always advisable to use it. Some people experience various unpleasant side effects and hence they can only take limited or no amount of it at all. Sometimes the effects are so severe that further administering can be dangerous.
Sildenafil is highly interactive with other drugs, such as nitrates, nitrites, other stimulants, alpha-blockers, CYP3A4 inhibitors, etc. Nitrates and nitrites that are used to treat heart disorders, as well as alpha-blockers, exert hypotensive effects, which, coupled with that of Viagra, can lead to a serious fall in blood pressure. This may impact your general condition very badly, causing light-headedness, dizziness, ringing in the ears, nausea, and faintness. There is even a possibility of a stroke. Therefore, concomitant use with the aforementioned medications is absolutely inadmissible. Co-administration with CYP3A4 inhibitors, such as erythromycin, ketoconazole or itraconazole, can hamper Sildenafil clearance, causing it to stay longer in the body.
The most common Viagra-related adverse events include headache, nasal congestion, flushing, impairment of color vision, chest pain, abdominal pain, diarrhea, and allergic reactions. The drug can also affect the functioning of the nerve stem, causing, neuralgia, neuropathy, anxiety, depression, insomnia, and somnolence; there have been incidence of metabolic disorders, such as hyper- and hypoglycemic reactions.
