Drug Uses
Viagra is intended for treating male sexual dysfunction. Taking Viagra helps to have and keep up erection during sexual activity.
How Taken
It is recommended to take Viagra 1 hour before the coitus. Still patients can take in a period from 4 hours to 30 minutes before the coitus.
Missed Dose
It is hard to miss the next dose of the medicine as it is taken as required. In case you have missed to take tablet you should take it at the moment you have remembered. In case it is the moment to take the medicine then don't take it and wait until the next time according to your plan. Note you shouldn't take tablet twice to fill up the missed one.
Storage
The medicine should be kept in its manufacturer's box. The temperature recommended to store Viagra is between 15 - 30 degrees C (59-86 degrees F) but preferably to store the medicine at 25 degrees C (77 degrees F).
Warnings Precautions
Do not take Viagra if you are taking any nitrate-based drug, including nitroglycerin patches (Nitro-Dur, Transderm-Nitro), nitroglycerin ointment (Nitro-Bid, Nitrol), nitroglycerin pills (Nitro-Bid, Nitrostat), and isosorbide pills (Dilatrate-SR, Isordil, Sorbitrate). Combining Viagra with these drugs can cause a severe drop in blood pressure.
If you have heart problems severe enough to make sexual activity a danger, you should avoid using Viagra. Use it cautiously if you've had a heart attack, stroke, or life-threatening heart irregularities within the past 6 months. Be equally cautious if you have severe high or low blood pressure, heart failure, or unstable angina.
If you take Viagra and develop cardiac symptoms (for example, dizziness, nausea, and chest pain) during sexual activity, do not continue. Alert your doctor to the problem as soon as possible.
If you have a condition that might result in long-lasting erections, such as sickle cell anemia, multiple myeloma (a disease of the bone marrow), or leukemia, use Viagra with caution. Also use cautiously if you have a genital problem or deformity such as Peyronie's disease. If an erection lasts more than 4 hours, seek treatment immediately. Permanent damage and impotence could result.
If you have a bleeding disorder, a stomach ulcer, or the inherited eye condition known as retinitis pigmentosa, use Viagra with caution. Its safety under these circumstances has not yet been studied.
