Compare Bactrim vs. Cipro

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Sulfamethoxazole/trimethoprim (Bactrim) and ciprofloxacin (Cipro) are both antibiotics used to treat bacterial infections, but they belong to different drug classes. Sulfamethoxazole/trimethoprim is a combination of a sulfonamide and an antifolate, while ciprofloxacin is a fluoroquinolone. Bactrim is often used for urinary tract infections (UTIs), ear infections, and lung infections, and it can be taken by both adults and children as young as 2 months old. In contrast, Cipro is typically reserved for more serious infections like bone and joint infections, sinus infections, and certain types of diarrhea, and it is generally prescribed for adults and children over 1 year old. Bactrim is available in both tablet and liquid forms, and it can also be given as an injection in a hospital setting. Cipro is available as a pill, oral solution, and injection. Both medications can cause nausea and diarrhea, but Cipro has more severe potential side effects, such as tendon rupture and nerve damage. Additionally, Bactrim is not recommended for people with sulfa allergies, while Cipro should be avoided by those with a history of quinolone allergies.
