Amoxicillin vs. Doxycycline: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on July 7, 2024
Amoxicillin is a penicillin antibiotic, while doxycycline is a tetracycline antibiotic.
Key Differences
Amoxicillin is an antibiotic that belongs to the penicillin family. Doxycycline, on the other hand, is a member of the tetracycline family.
Both of these antibiotics are used to treat a variety of bacterial infections. Amoxicillin is often prescribed for infections such as strep throat or ear infections, while doxycycline is commonly used for acne, Lyme disease.
The mechanism of action for amoxicillin involves disrupting the formation of bacterial cell walls, rendering them vulnerable. Doxycycline works differently, inhibiting protein synthesis in bacteria, thus stopping their growth.
Though both are antibiotics, they are prescribed for different conditions and have different side effects and interactions. It's important to note that amoxicillin can cause allergic reactions in those allergic to penicillin, whereas doxycycline is usually used as an alternative for those with penicillin allergies.
