Compare Cefdinir vs. Vibramycin

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

Key takeaways

Cefdinir (Omnicef) and doxycycline hyclate (Vibramycin, Doryx) are both antibiotics used to treat bacterial infections, including sinus infections. However, they belong to different medication classes. Cefdinir is a cephalosporin antibiotic, while doxycycline hyclate is a tetracycline antibiotic. Cefdinir is available as capsules and oral suspension, typically taken once or twice a day, and is often used off-label for urinary tract infections (UTIs) in children. Doxycycline hyclate comes in capsules, tablets, and liquid syrup, and is also used for conditions like acne and sexually transmitted infections (STIs). It is taken once or twice daily. Cefdinir can cause side effects like diarrhea and rash, and it interacts with antacids and iron supplements. Doxycycline hyclate may cause stomach upset and sun sensitivity, and it interacts with blood thinners and birth control pills. While cefdinir is generally safe during pregnancy, doxycycline hyclate is not recommended for pregnant women or young children due to risks of tooth discoloration and bone growth issues.
