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. Its primary activity is against susceptible forms of Streptococcus, Staphylococcus aureus (including MRSA), Escherichi...

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

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...

Sulfamethoxazole Tmp Ds Tablet

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.

Sulfamethoxazole Tmp Ds Tab What Is It Used For
2 Replies RSS
is it safe to take an expired persciption of the above medicine? from 2007 ## When it comes to any medication I think it is best to not take any chances with the past expiration date (especially in the event that it is almost 5 years old). They MAY still be ok to take if they haven't been exposed to a high amount of heat or various other conditions outside of the bottle, however I am not a pharmacist or MD, so I cannot guarantee if it is in fact safe for you to consume. There is still a high likelihood that it lost a lot of its potency and may be ineffective to the point where it could harm your body by not doing it's job all the way, per say. This is is most important when it comes to expired antibiotics, because the antibiotic may not kill the infection 100% and therefore can ...

Alcohol while taking sulfamethoxazole tmp?
2 Replies RSS
I'm taking sulfamethoxazole tmp and phenazopyridine and I'm having a party is it okay to have up to 3 beers? ## princess the alcohol will decrease the efectiveness of the sulfa ## I haven't read anything about alcohol decreasing the effects of Sulfamethoxazole/Tmp... but according to the University of Maryland Medical Center, using the two together has been known to cause serious side effects including but not limited to: a pounding heartbeat, rapid breathing, flushed skin, and increased perspiration (i.e sweating). That said, in my opinion it's probably not worth risking these symptoms for 3 beers. However in the event that you do experience such symptoms from ANY amount of alcohol, recommends that you contact your doctor immediately. I hope this helps!

I am self medicating with these 2 yr.old tablets that were given for my now deceased husband. I am on oxygen full time and for the past week, my breathing has gotten worse and I have pain in my right ear. I decided to cut out all of my herbal pills for eyesight and hair etc. to see if that was the cause. I still have shortness of breath. I figure I might have an infection going on so I am trying the Bactrim to see if that helps. I take a half pill a day of Digoxin - very low dosage. I have only taken one Bactrim, but so far, so good. Should I be taking Bactrim for my lungs? I know its ok for my ears. ## Hello, Suzy! How are you? I'm sorry that you're ill. This antibiotic can be used to treat various types of bacterial infections, as listed by the FDA. Possible side effects may i...
