Prior to taking amoxicillin for UTI if your doctor has prescribed it to you, you ought to make sure that amoxicillin is indeed safe for you to take.  Remember that you must not take amoxicillin for UTI if you are allergic to any penicillin antibiotics such as ticarcilin, ampicillin, or oxacillin.  To ensure that it is perfectly safe for you to take amoxicillin for UTI, inform your doctor if you have the following: asthma, kidney disorders, liver disease, a past history of diarrhea as a side effect of taking antibiotics; mononucleosis, and allergies to certain foods or other drugs.  In case you are currently undergoing treatment for gonorrhea, your physician may also ask you to be checked for syphilis, another type of STD (sexually-transmitted disease).

Note that should you take amoxicillin for UTI, it can render your birth control pills to be less effective or entirely useless.  Discuss with your doctor about the use of other birth control methods such as condoms if you wish to avoid getting pregnant while taking some amoxicillin for UTI.

The treatment of UTI with the use of antibiotics such as amoxicillin has to be designed specially by your doctor. It is usually based on your medical history, your current bacterial infection plaguing you, and the weakness of this particular bacterial infection to various antibiotic treatments.  Those who are deemed very sick typically will have to be under IV or intravenous antibiotics and they will be recommended to be admitted to the hospital for continuous monitoring – this is usually done because the patient might be having a kidney infection that can spread to their bloodstream.  Those who suffer from milder infections may become better quickly with just oral amoxicillin for UTI tablets.
