There is always need to be careful when you are taking the most mild of medications, not even to talk about prescription medications like Viagra. For example, even when you are taking medications like Tylenol, you need to make sure you do not take too much of it. Tylenol, for example, can cause liver damage if taken in doses that are too big. And that is just the basic example. Viagra is a much more potent medication and it is necessary to know which measures of precaution you need to take when you use it.
Firstly, Viagra is not taken according to a schedule like most other medications. It is taken when needed, meaning when you plan to have sex. You will need to take it at least an hour before the sexual intercourse. It takes an hour for Viagra to start working and once it does, you will have about 4 to 6 hours to spare. After that, the effects will subside. The most important thing to remember here is that you must not take another pill straight away. Only one pill is allowed in one 24-hour time period. Also, you must never take a double dose in order to improve the effects. The effects will stay the same and the duration will stay the same and you will only risk suffering from different side effects.
If you experience indigestion once you have taken Viagra or if you feel that your stomach is upset, you can take it with food as it will not affect the way in which it is
absorbed. You should take it with a full glass of water and you must not drink alcohol when using it. This is due to the fact that alcohol makes it much more likely that you will experience side effects. Furthermore, your blood pressure might become too low.
You must also avoid taking any other medication concomitantly with Viagra until the medication has been approved as safe by your physician or a pharmacist. You should also inform yourself about the possible side effects. If you experience symptoms like dizziness, nausea, or any pain or numbness in your neck, arms, jaw or chest during sex, you have to stop right away and contact your physician. You should do the same if you experience an erection that lasts more than 4 hours or that is painful.
