While you may be willing to try anything to correct erectile dysfunction, you have to take a close look at the downside of it all. There are many side effects that can occur when you use oral medications for this health concern. First, not everyone is healthy enough to engage in sexual activity. If you have serious heart problems or you take nitrates for chest pains, then you should refrain from using such medications. Taking them for erectile dysfunction can result in a heart attack, stroke, or death.

The most common side effect associated with such medications is a headache. Most of the time it isn't very strong, but it can become annoying because it lingers. This type of side effect should go away in a few days after the body gets used to the medication. Nausea or vomiting have also been reported, but they can often be reduced by taking the medication with a low fat snack or meal instead of on an empty stomach.

Some males experience diarrhea or constipation when they use medication for erectile dysfunction. This is also a side effect that should go away after a couple of days. If the diarrhea continues though you need to tell your doctor. It can lead to dehydration if it isn't corrected.

Nasal congestion is also quite common for males that use oral medications for erectile dysfunction. There are some more serious side effects that demand medical attention right away. If you experience an erection that lasts more than four hours you need to see a doctor. Otherwise, long term damage to the penis can occur.

Any changes in vision, hearing, or breathing needs to be reported immediately. Changes in heart rate are also something that you need to be very concerned about. The severity of side effects seems to increase as the dose of the medication dose. This is why it is always best to start out with a very low dose. It can then be increased if necessary to get the best benefits. Never take more than one dose of any such medication in a 24 hour period.
