Sulfamethoxazole Overview

Sulfamethoxazole (abbreviated SMZ or SMX)[1][2][3] is a sulfonamide bacteriostatic antibiotic. It is most often used as part of a synergistic combination with trimethoprim in a 5:1 ratio in co-trimoxazole (abbreviated SMZ-TMP and SMX-TMP,[4] or TMP-SMZ and TMP-SMX), also known under trade names such as Bactrim, Septrin, or Septra; in Eastern Europe it is marketed as Biseptol.

I Was Prescribed Sulfamethoxazole Tmp Ds For A Sinus Infection Week And Half Ago Suppsed To Take It 14 Days On My 9th Day At 6am Wok
2 Replies RSS
I was prescribed sulfamethoxazole tmp ds for a sinus infection and was to take it for 14 days. On my 9th day I woke up at 6 am having terrible muscle soreness and pain for no explainable reason. I couldn't lift my right arm without my bicep and forearm being in awful pain. As the day went on I still experienced pain but it seemed to diminish some. The next morning I woke at the same time and in worse pain. It was excruciating just to move. I tried reaching my doctor but decided to just stop taking the antibiotics. I only had 3 more days. The following day the pain was dull and almost non-exsistant. I had never had such a reaction in my life but I guess it's safe to say I'm allergic to this medication and will never forget it. ## That's actually not an allergic reaction, ...

My friend is very sick with empintago and was making sure he was not taking antibiotics that r in the penicillin family ## Hello, Bill! How are you? No, this is a generic for Bactrim and it is a sulfa based antibiotic. The FDA lists its typical side effects as possibly including nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help with?

I am currently controlling a utc with unsweetened cranberry juice, apple cider vinegar, cranberry supplements, L-argenine, saw palmetto etc. How can I order sulfamethoxazole tmp ds tabs without going to a MDDale ## Hello, Dale! How are you? I'm sorry about the problem that you're having. No, this medication requires a doctor's visit and prescription in the U.S. Have you spoken to your doctor about the problem?

white oblong pill vp 50

This pill is white and oblong. It has a print of VP50 on one side and nothing on the other side. ## @Whitaker, Based on your description, the closest match I could find was a white oblong shaped pill marked with VP 120 on one side and blank on the other. It's reportedly identified as a Sulfamethoxazole (800mg) + Trimethoprim (160mg) DS tablet, used for treating a variety of bacterial infections. I realize the imprint isn't spot on, but because they are very similar, I have a strong feeling that they could be made by the same manufacturer (Vista Pharmaceuticals). Perhaps you can try contacting them directly for more specific details on whether VP 50 is something they make. The phone number/extension to reach them at is listed on their website as 973-736-1952/4457; based out of We...

how long is smz 200 40 5 it good
1 Reply RSS
How long is this medicine good for. ## Hi rae, According to Roche Pharmaceuticals, the tablets as well as the oral suspensions of sulfamethoxazole + trimethoprim both have a shelf life of 5 years. However I'm assuming this is based on their recommended storage temperature being below 30 degrees celsius (86*F). On the contrary, a news article by the LA Times suggests from prior studies that many medications are actually good for up to 40 years beyond the listed expiration date. They also go on to state that expiration dates are often set solely based upon one's own discretion without a specific reason or evidence indicating that it truly has expired. And apparently the reason behind this is that the FDA doesn't require pharmaceutical companies to check how long their ingredie...

mouth palate and tongue feel raw while I am on this medicine........should I stop. ## Trimethoprim + Sulfamethoxazole can cause mouth sores as a severe side effect, but I haven't read anything related to what you're describing. My assumption is that if this side effect becomes too bothersome or persistent, then you should consider contacting your doctor about stopping the medication and opting for a safer or more natural alternative. How long have you been taking it for? ## I have just taken my first pill of Bactrim for a MRSA infection i developed on my arm. Before taking my pills I usually pin them with the underside of my tongue, but where the pill touched is now painful and swollen. My best advice is to just take the medicine as quickly as possible because it contains sulfur...

My Dr prescribed me 20 Sulfamethoxazole Tmp. So far I have taken 10 tablets and from yesterday I have started getting chills, headache, sore throat and body ache.
