Sulfamethoxazole Overview

Sulfamethoxazole (SMZ or SMX), is an antibiotic. It was used for bacterial infections such as urinary tract infections, bronchitis, and prostatitis and is effective against both gram negative and positive bacteria such as Listeria monocytogenes and E. coli.[1] Common side effects include nausea, vomiting, loss of appetite, and a rash.

Are expired antibiotics toxic?
1 Reply RSS
Is it safe to take sulfamethoxazole/tmp when it expired 3 years ago? Is it toxic or does it lose some of its effectiveness? ## Hello, Lee! How are you? No, it does not become toxic, but yes, it can lose some effectiveness, so it may not fully eradicate the infectious bacteria, which means that it may develop antibiotic resistance. Thus, it would be better to see your doctor for a new prescription. The FDA lists the typical side effects of most antibiotics as possibly including nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help with?

drank alcohol while taking sulfamethoxazole
1 Reply RSS
My boyfriend drank while on sulfamethoxazole. Now he feels like poop. He is suffering. So my question is, what now? Should he go to the drs again? Wait it out? Obviously he isn't drinking tonight, lol but i also think he should wait to continue the prescription, once the alcohol is out of his system.... These are being taken for more of a "preventive" infection from a spider bite he got at work. So, once he's free of these nasty enhanced side effects he can then continue the prescription (he only took 2 pills, before consuming beer). Thanks in advance. Oh and if you are thinking of drinking while on this, i would think twice. Its equivalent to the flu. ## Hello, Crystal! How are you? Unless his doctor instructs otherwise, it really should just be a matter of waiting it o...

does sulfamethoxazole contain sulfa

I am allergic to sulphur does smz/temp dos have sulphur in it ## Hello, Marie! How are you? Yes, it is a sulfa based antibiotic, so there is a chance you may be allergic to it. The FDA warns that allergic reactions to it may include symptoms, such as nausea, dizziness, trouble breathing, hives, itching and possibly anaphylactic shock. However, if you are only allergic to sulfur, you might be able to take it. I am allergic to this antibiotic, but I am not allergic to sulfur. How did you discover you were allergic to it? That might help clear this up, because they are different. ## I used a sulfer medication for a UT I 30 minutes later I started hives. I must note that the medication had expired

I took my last pill last night. Its been 12 since. Is it ok to have a drink now? ## I meant it's been 12 hours since my last pill ## Hello, Cece! How are you? It could still cause you to experience more side effects than usual, as reported by the FDA. So you may get more nauseous, dizzy and drowsy than usual, because the medication will still be active in your body. However, if your doctor approves of your imbibing, please make sure that you aren't driving and won't be operating any dangerous machinery. Is there anything else I can help with?
