Sepnil 400 mg/80 mg Tablet
What is Sepnil 400 mg/80 mg
Sepnil 400 mg/80 mg tablet is an antibiotic combination designed to treat various bacterial infections affecting the urinary tract, respiratory system, gastrointestinal tract, and other body parts. The medicine contains a combination of FDA-approved ingredients: Sulfamethoxazole (400 mg) and Trimethoprim (80 mg), which belong to the sulfonamide class of antibiotics. Tosc International, India, manufactures these tablets in GMP-compliant facilities.
This antibiotic combination works synergistically by blocking two consecutive steps in the bacterial synthesis of folic acid, which is important for bacterial growth and reproduction. Sulfamethoxazole inhibits the incorporation of para-aminobenzoic acid into folic acid, while Trimethoprim blocks the reduction of dihydrofolic acid to tetrahydrofolic acid. This dual mechanism makes the combination highly effective against a wide range of bacteria.
The recommended dosage is typically one to two tablets taken twice daily, with doses spaced 12 hours apart. The tablets should be taken with a full glass of water, and it is important to maintain adequate fluid intake during treatment. The complete course should be finished even if symptoms improve to prevent antibiotic resistance.
Common Sepnil side effects may include nausea, vomiting, loss of appetite, diarrhea, headache, and skin rash. These are generally mild and temporary, resolving as your body adjusts to the antibiotic. Contact your doctor if any of these side effects become severe or worsen.
Before taking Sepnil 400 mg/80 mg, inform your doctor about your complete medical history, especially if you have kidney disease, liver disease, blood disorders, Asthma, severe allergies, or Glucose-6-phosphate dehydrogenase (G6PD) deficiency. Pregnant and breastfeeding women should use this medicine only under strict medical supervision.
