Can metronidazole and amoxicillin be taken together?
Generally, common dosage forms of metronidazole include metronidazole tablets and metronidazole suppositories. Common dosage forms of amoxicillin include amoxicillin granules and amoxicillin capsules. Metronidazole and amoxicillin usually can be taken together under medical guidance. Detailed explanation is as follows:

Metronidazole is a synthetic antimicrobial medication effective against anaerobic bacteria and parasites such as trichomonas, amoeba, and Giardia lamblia, but it has no effect on aerobic bacteria. Amoxicillin is a semi-synthetic penicillin-class antibiotic that kills only aerobic bacteria and has no effect on anaerobic bacteria or parasites. Since metronidazole acts against anaerobic bacteria and parasites while amoxicillin acts against aerobic bacteria, the two medications may be combined for therapeutic needs. There is no incompatibility between the two drugs, and their combined use does not interfere with or counteract each other, thereby reducing efficacy.
All medications should be used under the guidance of a physician to ensure safe and effective treatment of diseases.
