Early Period With Metronidazole

Updated

I started taking Metronidazole tablets today (Nov. 4th), which the doctor prescribed to take 3 times a day for 5 days. My period is due on Nov. 9th. On the first day I started taking the tablets my period came and it is early. Is this normal or should I be worried?

Hello, Joy! How are you? Are you using any type of hormonal contraceptive?

If so, that may explain it, according to the NIH, many antibiotics are known to alter the efficacy of hormonal contraceptives.

Other side effects, according to the U.S. FDA, may possibly include nausea, dizziness, headache, and stomach pain.
