Viagra

Viagra (sildenafil) is a phosphodiesterase inhibitor used for the treatment of male impotence. Patients diagnosed with this condition are usually unable to achieve erections that would be hard enough for them to have sex. Viagra helps with the problem if taken about 60 minutes before you are planning to have sex. Viagra then provides for up to 6 hours of efficiency, although some patients may experience the effects during a shorter period due to their individual factors. Therefore, it's best to have sex after 60 minutes pass, as Viagra is most efficient then. Once you have completed sexual intercourse, your erection will go away as usual. Taking more of Viagra is not going to provide for 10-12 hours of efficiency etc. and may cause an overdose. Although an overdose of Viagra is not expected to be life threatening, you may develop priapism – a prolonged and painful erection that can cause damage to the tissues of the penis. If you think you may have developed priapism, seek emergency medical assistance. Viagra has been reported to interact with a wide number of drugs, such as erectile dysfunction medicines, efavirenz, delavirdine, phenytoin, alpha blockers, high blood pressure medications, phenobarbital, irregular heartbeat drugs, carbamazepine, cimetidine, amiodarone, erythromycin, HIV protease inhibitors, clarithromycin, paroxetine, metronidazole, and antifungals. This is not a complete list of all the possible interactions, but the drugs mentioned represent the most commonly prescribed ones. Even if you are taking any herbal preparations of vitamins, it's worth mentioning this fact to your health care provider to rule out dangerous interactions. Viagra is not intended for pregnant or breastfeeding women and should not be taken by females in general. You need to be aware of both serious and mild side effects associated with taking Viagra to make sure you know which ones need to be reported and which ones are likely to go away on their own. The following serious side effects should be reported as soon as possible (although they are quite rare): shortness of breath, sudden hearing loss, prolonged penis erection (priapism), chest pain, irregular heartbeat, sudden vision loss, swelling, sweating, general ill feeling, lightheadedness, and nausea. In most cases, however, you will get only minor side effects that can be tolerated and will go away in a couple of hours. The following ones are considered to be insignificant and shouldn’t be reported to your health care provider: headache, insomnia, diarrhea, flushing, numbness, burning, or tingling, muscle aches, heartburn, nosebleeds, and light sensitivity. Please make sure you never share your dosage of Viagra with other people to whom it was not prescribed, as it can be dangerous if taken by people with a number of contraindications and health conditions that need to be taken into consideration. Talk to your doctor if you think you need a dose adjustment, but do not change it yourself.
