Erectile Dysfunction Causes
There are many erectile dysfunction causes. Sometimes it's caused by a health condition. Other times, lifestyle plays a role. But blood flow is always important. If blood is prevented from properly flowing to the penis, it can lead to erectile dysfunction.
Sometimes, ED can be caused by a medical condition.
Many conditions including diabetes, high cholesterol, and hardening of the arteries can affect blood flow in the body. And this can lead to ED. Also, depression can lead to ED.
Other times, it's caused by medications.
Some medicines that men take for conditions like high blood pressure and depression can lead to ED.
Lifestyle factors can also play a part.
For example, smoking can damage blood vessels. And it can lead to hardening of the arteries. This may prevent blood flow to the penis and can cause ED.
Learn more about these erectile dysfunction causes below.
If any apply to you, be sure to mention them during your VIAGRA Talk with your doctor.
VIAGRA is prescribed to treat erectile dysfunction (ED).
IMPORTANT SAFETY INFORMATION BELOW.
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.
Please see full prescribing information for VIAGRA (25 mg, 50 mg, 100 mg) tablets.
