Medical Overview
Bactrim is listed as Antibiotic containing Sulfamethoxazole + Trimethoprim. An antibiotic used for selected bacterial infections; it does not treat viral colds.
Bactrim (trimethoprim-sulfamethoxazole) is the classic combo enjoying a global comeback for UTIs and community MRSA skin infections, and the key prophylaxis for immunosuppressed patients. Ask about sulfa allergy first; any rash = stop and review; hydrate well; beware the strong warfarin interaction.
Uses / Indications
- Urinary tract infection
- ear infection
- prophylaxis of PCP
- Bacterial infections selected by a clinician based on infection site and likely organisms.
Side Effects
- أشيعها: غثيان وفقدان شهية وطفح جلدي (أعلى العائلات إحداثاً للطفح — أي طفح يستدعي إيقافاً ومراجعة لاستبعاد تفاعلات جلدية خطيرة نادرة). قد يرفع البوتاسيوم والكرياتينين قليلاً
