Finding the right VIAGRA dose

VIAGRA has been shown to help men with erectile dysfunction (ED) achieve harder erections. So if you aren’t getting the erections you want, don’t give up.

For some men, VIAGRA begins working the second or third time. For others, a simple dose adjustment can make all the difference.

VIAGRA comes in 3 doses: 25 mg, 50 mg, and 100 mg
There are 3 doses of VIAGRA: 25 mg, 50 mg, and 100 mg. Doctors usually start their patients on the 50-mg tablet. It’s been shown that VIAGRA 100 mg works better.

If you are over 65, or have serious liver or kidney problems, your doctor may start you out on VIAGRA 25 mg. And if you are on protease inhibitors, your doctor may prescribe VIAGRA 25 mg and limit how often you take it.

Norm’s story
“My initial prescription from my doctor was for 50 milligrams of VIAGRA. And it did work. But after a couple of months, my doctor had asked me to come back in for a follow up. She asked me pertinent questions about how things were going. And I told her, it’s working fine. And I said, but maybe it could be a little bit better. And she said, let’s up the dosage, to a hundred milligrams. That’s where I am today. I’ve used the 100 milligrams for the past few years and frankly, I couldn’t be happier with it.”

“VIAGRA is prescribed to treat erectile dysfunction in men. Here’s important safety information about VIAGRA. Ask your doctor if your heart is healthy enough for sex. Don’t take VIAGRA if you take nitrates for chest pain, as it may cause an unsafe drop in blood pressure. Side effects may include headache, flushing, upset stomach, and abnormal vision. Stop taking VIAGRA and call your doctor right away if you experience a sudden decrease in vision or hearing. To avoid long-term injury, seek immediate medical help for an erection lasting more that 4 hours. Remember, VIAGRA does not protect against sexually transmitted diseases, including HIV. Ask your doctor if VIAGRA is right for you.”

VIAGRA is prescribed to treat erectile dysfunction (ED).

Important safety information

Do not take VIAGRA if you take nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure.

Discuss your general health status with your doctor to ensure that you are healthy enough to engage in sexual activity. If you experience chest pain, nausea, or any other discomforts during sex, seek immediate medical help.

In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.

If you are older than age 65, or have serious liver or kidney problems, your doctor may start you at the lowest dose (25 mg) of VIAGRA. If you are taking protease inhibitors, such as for the treatment of HIV, your doctor may recommend a 25-mg dose and may limit you to a maximum single dose of 25 mg of VIAGRA in a 48-hour period.

In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including VIAGRA) reported a sudden decrease or loss of vision. It is not possible to determine whether these events are related directly to these medicines or to other factors. If you experience sudden decrease or loss of vision, stop taking PDE5 inhibitors, including VIAGRA, and call a doctor right away.

Sudden decrease or loss of hearing has been rarely reported in people taking PDE5 inhibitors, including VIAGRA. It is not possible to determine whether these events are related directly to the PDE5 inhibitors or to other factors. If you experience sudden decrease or loss of hearing, stop taking VIAGRA and contact a doctor right away.

If you have prostate problems or high blood pressure for which you take medicines called alpha blockers, your doctor may start you on a lower dose of VIAGRA.

VIAGRA should not be used with other treatments that cause erections. VIAGRA should not be used with REVATIO as REVATIO contains sildenafil, the same medicine found in VIAGRA.

VIAGRA does not protect against sexually transmitted diseases, including HIV.

The most common side effects of VIAGRA are headache, facial flushing, and upset stomach. Less commonly, bluish vision, blurred vision, or sensitivity to light may briefly occur.
