shelf life sulfamethoxazole
6 Replies RSS
I want to long-term store sulfamethoxazole for potential emergency use. What is the PRACTICAL shelf-life of this antibiotic? Forget about the manufacturer's statements. I want a real-world shelf life and storage instructions. ## From what I could gather, the estimated shelf life of the oral suspension and tablets are both 5 years. The manufacturer's storage instructions also suggest keeping it at room temperature and out of direct sunlight (below 86 degrees fahrenheit), to help prevent further degradation. According to a Harvard Medical School family health article, most types of medications are actually safe to use up to 10 to 15 years after their supposed expiration date listed by the manufacturer. However, there are some antibiotics in the Cycline class, which can be dangerou...

Hi, I have some sulfamethoxazole 800/160mg and the prescribed date was 9/17/2013 and I was wondering if it is ok to still use? Thank you!! ## Hello, Joe! How are you? If you think you have an infection that requires an antibiotic, it would be best to see your doctor for a new prescription. Medications tend to lose effectiveness over time, which means that this one may no longer completely eradicate the bacteria, which puts you at risk of developing antibiotic resistant bacteria. 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? ## No, thank you very much. I will ask the doc and so thanx again. ## Have a raging uti can't get to doc til Tomorrow Generally take sulfameth...

can you take pain medication with sulfamethoxazole
1 Reply RSS
I am itching all over from a reaction to Bactrim DS. Can I take a Percocet with it? How does it interact? ## Percocet will not do anything to stop the itching. It is an opiate narcotic that is used to alleviate pain. The FDA warns that it carries the risk of being habit forming and may cause side effects, such as nausea, dizziness, headache, constipation and dry mouth. As to the itching, you might be allergic to the Bactrim DS, so it would be best to see your doctor and have this checked out. Such allergies tend to worsen with repeated exposure, so you may need to switch to a different antibiotic. How are you doing, now? Has there been any change?

Is Ilvitrim Suspension good for my HIV negative baby? The doctor prescribe it while she was having a short breath problem. Thanks ## Hi Fanyana, Based on my research, Ilvitrim contains the active ingredients Sulfamethoxazole + Trimethoprim; a sulfonamide antibacterial combination that is used in the treatment of a variety of bacterial infections. (not just limited to HIV). If your child's doctor prescribed it for what appears to be an upper respiratory or sinus related infection, Ilvitrim does sound like an appropriate medication for the job. However if you're asking whether or not a powerful antibiotic like this is good for your baby, my personal answer would be no, due to it's high risk of side effects. In which case, I would personally consider other more natural alternat...

Sulfamethoxazole Tmp Ds My Dr gave me this when I am pregnant

My Dr gave me Sulfemethoxazole DS by accident when I am 6 weeks Pregnant, What has it done to my Baby girl? Do I worry until she is born? ## Sulfamethoxazole with Trimethoprim is an antibiotic, commonly prescribed under the brand name Bactrim and while it has been shown to carry some risk, when used during pregnancy, no controlled studies have been done to definitively prove exactly what those risks are. And yes, unfortunately, until the baby is born, there is really no way to know if any harm has been done. On thing you may want to do, however, is talk to your doctor to make sure you are taking a Folic Acid supplement. May pregnant women do not get enough in their diets and a lack of it has been known to cause birth defects. On top of that, the antibiotic has been known to prevent it f...
