Drug Uses
Viagra (Sildenafil Citrate) works towards enhancing the blood flow in the penis thereby allowing an individual to maintain an erection for a longer period while indulging into a sexual act.
One needs to consume the drug an hour before getting into any sexual activity. It is important not to exceed the normal dosage, which means do not take it more than once in a day.
You need to use Viagra only when necessary and therefore, do not follow any specific schedule. You need to store the medication in containers specially meant for it.
Make sure that the temperature is somewhere between 59 and 86F that equals to around 15 to 30C. The storage place should be free from moisture, light and heat.
Warning/Precautions
Avoid Viagra if you are already using a nitrate medication for treating heart problems and chest pains. This also includes nitroglycerin, isosorbide dinitrate, isosorbide mononitrate or a recreational drug.
Before opting for Viagra, inform the doctor about the other drugs that you are currently using for treating erectile dysfunction.
Please contact your doctor if you are using Warfarin, Bosentan, Erythromycin or Clarithromycin, Cimetidine, Amprenavir, darunavir, Tipranavir, Efavirenz, Nevirapine, Indinavir, Iopinavir/Ritonavir, Saquinavir, ritonavir, nelfinavir, atazanavir and fosamprenavir.
Some other medications that call for a consultation from your doctor before you take Viagra are Doxazosin, Terazosin, Prazosin, Itraconazole or Ketoconazole, Rifampin or rifabutin, Carbamazepine and phenytoin or Phenobarbital.
Inform your doctor about all the drugs prescribed to you by other physicians. These drugs also include herbal, vitamin and mineral drugs.
If you are suffering from a severe heart disorder and your doctor has suggested you to refrain from any sexual activity, then do not use Viagra.
Have a talk with your doctor, if you recently suffered from a heart attack or a stroke. The same also applies to men suffering from low or high blood pressure or an unstable angina.
Do not continue the medication if you witness symptoms such as nausea, chest pain or dizziness during sexual activity. Consult your doctor and inquire about the necessary steps that you need to take in future.
Also, take necessary precautions if you suffer from any genital problems. In case, the erection lasts for more than 4-hours, you need to seek immediate medical attention, as this may result into permanent damage.
