Can Erythromycin and Metronidazole be taken together for tooth infection?
Patient: Hi doctor,  Can I take erythromycin and metronidazole together? I have a very severe tooth infection and have been prescribed metronidazole and a couple of days later erythromycin and advised to continue with both courses. However I have started to suffer with nausea and vomiting,  is this due to the 2 sets of antibiotics? Doctor: Thanks for your query, I have gone through your query.The combination of these two antibiotic works well against the tooth infection.The reason for the vomiting and nausea can be because of the gastric irritation caused by these drugs particularly metronidazole.Nothing to be panic, You can take an antacid like ranitidine 150mg BID and Domperidone BID before food and later take the antibiotics after food. If the vomiting does not stop after these medicines, then immediately consult a general physician. Consume lot of liquid.I hope my answer will help you, take care.
