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. It is a sulfonamide and bacteriostatic. It resembles a component of folic acid. It prevents folic acid synthesis in the bacteria that must synthesize their own ...

sulfamethoxazole tmp ds tablet side effects
6 Replies RSS
I had a pillar cyst removed from the back of my head and the wound got infected, so the doctor prescribed this med to clear it up. Wow! I have never had an allergic reaction to anything in my life, but this drug knocked me for a loop. I thought I had the stomach flu one day--kept trying to throw up, diarrhea, stiff neck, headache, feverish, affected my vision. I slept the entire day. I stopped taking the med because my stomach wouldn't tolerate anything. The next day, I started to feel better, so started back on the med and the symptoms came back with a venegaence--. that's when I looked up the side effects and called the doctor. I got into the shower after that and noticed I had a horrible rash all over the upper part of my body. It's been almost 24 hours since I stopped ta...

Need help with side effects from sulfamethoxazole tmp ds
1 Reply RSS
Friend needs help. Treated with this medication for infected skin strep. Has fever to the point of chattering teeth, major body aches, extreme fatigue, splitting headache, diarrhea. Went to doctor who just told him not to take meds anymore. Any suggestions on how to help? ## Hello, Cliff! How is your friend doing? Unfortunately, those can be side effects of this medication and, once it is discontinued, the only thing that will help is time. I had a bad allergic reaction to it several years ago and it took about 2 weeks for all of the symptoms to go away. If his doctor approves, some Benadryl may help with some of the symptoms, as well as Imodium for the diarrhea. Beyond that, it's just a waiting game. However, as explained by the NIH, such side effects or allergic reactions tend to ...

My husband has been on this med for 2 days and feels terrible. How long should it be defore he feels better. Thanks ## Hello, Darothy! How are you? Has there been any change, yet? The general rule with antibiotics is that if they are working, you shouldn't see any worsening of the infection after taking them for a full 24 hours and you should start to see improvement after taking them for a full 72 hours. The FDA lists the typical side effects of this medication as possibly including nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help with?

ip 272 can it be used for
1 Reply RSS
can you give to pigs for antobiotics for wounds ## Hi Lisa, IP 272 is reportedly identified as Sulfamethoxazole + Trimethoprim DS (800mg/160mg). From what I could gather, this antibiotic is not FDA-approved for veterinary use. However I have read about several cases of veterinarians still prescribing Sulfamethoxazole + Trimethoprim DS for cats and dogs... Pigs on the other hand, I have no idea. But what I would recommend doing is disclosing all of your animal's medication history to the veterinarian in order to better determine whether Sulfamethoxazole + Trimethoprim is the most appropriate form of treatment. I hope this helps!

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...
