I amon 500 mg Flagyl for an infected gland after a severe root canal .....tooth was ok however the root was soooo infected. I was on penicillin for a week, now this. It feels like it is healing, however I feel so sick this second day. How long will this last, as my body adjusts, or will I suffer for the 2 weeks I am on this antibiotic? Thanks
DEAR FRIEND. Thanks for sharing your concern. Penicillin along with Flagyl (metronidazole) is usually prescribed during root canal treatment, as it takes care of both aerobic and anaerobic infections very well. This is very much required in cases of root canal treatment. In your case, if you are not finding comfortable using this combination then you can visit your dentist and another set of antibiotics can be prescribed for you, like augmenting or cephalosporins etc. Need not worry, you will be fine once your root canal treatment is completed. You will be problem free. There are no nerves left in the tooth, to cause you pain after root canal, so relax, it will get over. Meanwhile, if you wish, you can visit your dentist regarding the discomfort faced by with the present set of Chat Doctor.  Also do frequent warm saline rinses and maintain very good oral hygiene. This will help you in reducing oral infection. Hope it helps .take care. Thanks
