Bactrim DS Tablet

What is Bactrim DS

Bactrim DS is a Sulfonamide antibiotic that treats bacterial infections, such as Urinary Tract Infections (UTIs), respiratory, skin, and sinus infections. It contains FDA-approved active ingredients Sulfamethoxazole (800 mg) and Trimethoprim (160 mg), which work together to stop bacterial growth.

Manufactured by Abbott Healthcare Pvt. Ltd. in a GMP-compliant facility, Bactrim DS offers broad-spectrum antibacterial action. It requires proper dosing according to the type of infection, with awareness of potential side effects to ensure safe use.

Uses of Bactrim DS

It is a combination antibiotic used to treat various forms of bacterial infections. Common Bactrim DS uses include:

• Urinary Tract Infections (UTIs) caused by E. coli and other bacteria
• Respiratory Tract Infections (RTIs), such as Acute Bronchitis
• Middle ear infections (Otitis Media) in children
• Shigellosis, a form of Dysentery
• Pneumocystis Pneumonia (PCP), especially in immunocompromised individuals
• Traveler’s Diarrhea (TD) caused by specific bacteria

These uses reflect its FDA-approved indications, but there are also non-FDA-approved uses, which a clinician or doctor may prescribe.

Working and benefits of Sulfamethoxazole and Trimethoprim

Bactrim DS contains two active ingredients, Sulfamethoxazole and Trimethoprim. These ingredients work together to stop bacteria from growing and multiplying in the urinary tract, skin, lungs, and sinuses.

Sulfamethoxazole blocks bacteria from producing Dihydrofolic acid (DHF), a building block needed to make proteins and DNA. Trimethoprim prevents the next step by stopping bacteria from producing Tetrahydrofolic Acid (THFA), another essential component for bacterial survival. By blocking two steps in this folic acid pathway, Bactrim effectively kills bacteria and stops infections from spreading.

The benefits of Bactrim DS’s active ingredients include:

• Broad antimicrobial action against many types of bacteria
• Effective in treating urinary, respiratory, skin, and gastrointestinal infections
• Helps reduce bacterial growth quickly to lower infection severity
• Combination therapy provides stronger bactericidal effects than single antibiotics
• Supports faster recovery and prevents the return of infection

This antibiotic combination is FDA-approved and manufactured in GMP-compliant facilities, ensuring the quality and safety of the treatment for infections such as UTIs, Sinusitis, Cellulitis, and more.

Disease Interactions

Certain health conditions may require dose adjustments or avoidance of Bactrim DS. Consider the following:
