What happens if you take amoxicillin 500mg 4 hours early than you are supposed to my doctor prescribed it for every 7 to 8 hours?

Answer 1

You take penicillin exactly as your doctor has told you to take it - do not take it if you have not seen a doctor and actually been tested to make sure you have an infection. It's not going to help if you have a virus, and will just make you resistant to it so it won't work in the future. Penicillin is usually taken every 6-12 hours however.

Answer 2

Yes. Penicillin can be taken every four hours. But is is usually not needed. Your physician will give you usually three to four times a day. Even two times a day dose is enough to cure you of strep throat. But some times the patient may forget to take the dose. Then it becomes once a day dose. It is not enough to cure strep throat. So the wise physician will give a dose of penicillin three times a day. So even if one dose is missed, there is no problem.

Answer 3

Yes. You can take amoxicillin every four hours. But then it has most probably no advantage, in most of the infections over taking every eight hours.
