Viagra Directions? |
|
| |
A typical beginning dose of Viagra is 50-100 mg for men aged 18-65. Older patients are usually given a 25 mg dose, Viagra may be taken with or without food, though high-fat foods may cause it to be absorbed more slowly, and therefore take a little longer to start working.
If needed, the pills can be broken or crushed before swallowing. Viagra should be taken no more than once a day, and should not be taken every day without a doctor's approval. It's best to take Viagra about one hour before sexual intercourse. It is usually effective anytime for between half an hour and four hours.
Viagra works by increasing the blood flow into the area, which allows men to achieve and maintain erections. It is not an aphrodisiac and does not contain hormones. Viagra will not automatically cause an erection.
Viagra works for almost all men who use it. In studies, more than 4 out of every 5 men taking Viagra had better erections. It works no matter how long they have had ED, what caused it, or how old they are.
The medication can become effective very quickly. For some it works as fast as 30 minutes, but will remain effective for as long as four hours. Take a pill once a day as desired. |

Viagra Side Effects? |
|
| |
Never take Viagra at the same time as grapefruit juice. The interaction of these two can increase your risk of unpleasant side effects.
A small percentage of men experience congestion, dry eyes, and altered vision (blue tint or haze) when using Viagra.
Mild side effects include flushing, rash, indigestion, headache, light sensitivity, and the inability to distinguish between blue and green. These should subside, but if they do not or are bothersome, let your doctor know.
There are also some potentially serious side effects associated with Viagra. Seek emergency medical assistance if you experience arrhythmia, blood sugar problems (in patients with history of diabetes), decreased blood flow to the heart, heart attack, priapism (prolonged and painful erection), seizures, swelling or redness of the eyes, or temporary blindness.
Make sure your doctor knows if you have had a heart attack; irregular heartbeats; bleeding disorder; sickle cell anemia; multiple myeloma; leukemia; heart, kidney, or liver disease; angina; a stroke; high or low blood pressure; conditions affecting the shape of the penis (e.g., angulation, cavernosal fibrosa, or Peyronie's disease); or retinitis pigmentosa. |
