Each row is one product from one pharmacy, shown in the pack size with the lowest price per unit; its other pack sizes are listed under “other pack sizes”. Price per unit = the pack price divided by the units in the pack, before shipping; we sort by it and don't assume how long a pack lasts. Total with shipping = the pack price plus the pharmacy's shipping fee for one order. Prices checked Nov 12, 2026 on each pharmacy's website, in U.S. dollars (converted when a pharmacy prices in Canadian dollars). The lowest price at the top of this page uses only packs whose maker the pharmacy names, or whose product country and ships-from country it states. Prices change often; confirm at checkout. U.S. rows: the cash price a U.S. pharmacy published on its own website on the date shown, plus its standard shipping; no insurance or discount cards. “Fee not published” means the pharmacy doesn’t show its shipping fee before checkout, so that row’s total is the medicine price only.

Sun Pharma lists brand Bactrim DS at $259.96 for 100 tablets and regular Bactrim at $144.05 for 100 (Texas DSHS). These are list prices (the maker's wholesale price before discounts); what a pharmacy charges can differ. In the FDA's Orange Book the Bactrim tablets application is marked discontinued, but Sun still lists both tablets with the FDA (FDA NDC Directory) and reports 2026 list prices, so we treat brand Bactrim as still sold.

What is Bactrim used for?
Bactrim (sulfamethoxazole and trimethoprim) is an antibiotic that combines two medicines. According to its FDA label (DailyMed), it is used to treat or prevent certain infections caused by bacteria, including:
- Urinary tract infections.
- Ear infections (acute otitis media) in children.
- Flare-ups of chronic bronchitis in adults.
- Shigella infections of the gut, and travelers' diarrhea in adults.
- Pneumocystis jirovecii pneumonia (PCP): treatment, and prevention in people with weakened immune systems.
Bactrim comes as 400 mg/80 mg tablets and 800 mg/160 mg double-strength (DS) tablets. For a urinary tract infection, the label's usual adult dose is 1 DS tablet (or 2 regular tablets) every 12 hours for 10 to 14 days; other infections use different doses. It isn't for infants under 2 months or people allergic to sulfa drugs or trimethoprim, and people with kidney problems may need less. Antibiotics don't work for colds or flu. Your prescriber decides which medicine is right for you.
Is it safe to order Bactrim from Canada?
Many Americans do, but U.S. law and customs rules apply, and for Bactrim, compare the U.S. price of FDA-approved generic sulfamethoxazole and trimethoprim before you order. Federal law generally doesn't allow individuals to import prescription drugs, though under its personal importation policy the FDA has long used enforcement discretion for some personal-use shipments, generally no more than a three-month supply (FDA). Congress has said enforcement against individuals should focus on imports that pose a significant threat to public health (Federal Food, Drug, and Cosmetic Act section 804(j)(1), 21 U.S.C. 384(j)(1)). You need a prescription from your doctor. New U.S. Customs rules for mailed orders start January 20, 2027. In Canada, Health Canada lists Roche's Bactrim tablets as cancelled (Health Canada, checked 2026-11-12), so we don't show Canadian brand Bactrim tablets.
