2. Precautions

There are a few things that you have to be aware of before use.

【Meals before taking a dose】

The medicine works best on an empty stomach. You could also take the medicine after a meal or light snack, but the effects might take longer to show than in the chart listed above. If you decide to take the medication after a meal, be sure to: ① take it a couple of hours after your meal and ② avoid eating a lot and fatty foods.

Alcohol in moderation can help relieve tension and bring out better results, but the user should know that heavy drinking can negatively affect your erection and nervous system. Regardless of whether you take the medicine or not, drinking too much alcohol and not in moderation is detrimental to your body.

【Side effects】

The medicine for ED treatment has some side effects.

The blood vessels are dilated not just in the penis, but all throughout the body. Common side effects caused by this are hot flashes and flushing. Other side effects could include chest pain, palpitations, tachycardia, and dizziness as well.

If you are taking antihypertensive medication, consult with your doctor before taking ED treatment medication: the combination could lead to extreme cases of low blood pressure.

【Those undergoing treatment for other diseases】

For all three medications for ED treatment, there are contraindications (medicine that should not be taken at the same time, such as nitrates). Even if you are not taking any medication, you need to be careful if you are on dialysis or have a history of stroke or cerebral hemorrhage. Also, elderly people over 65 years old need to be careful when taking these treatments for ED. For more details, please consult with your doctor each time to make sure there is no problem.

Regardless of what ED medical treatment that you decide to take, all of them should only be taken once a day. The next dosage should be taken 24 hours after you took the previous dose.

It is important to discuss with a medical professional about which medication best fits your own needs and physical conditions, so if you have any questions, please be sure to consult the doctor first.
