Product introduction

Wemdazole Injection helps prevent an infection after surgery. It is also used in the treatment of dental infections, leg ulcers, and pressure sores. This injection is administered under the supervision of a healthcare professional. It should be taken at the same time each day to get the most benefit. Your symptoms may get better after a short time but do not stop taking it until you have finished a full course of treatment, even if you feel well. If you stop taking it early, some bacteria may survive, and the infection may come back. Do not drink any alcohol while taking this medicine, and for a few days after stopping it. Otherwise, you may get unpleasant side effects like nausea, vomiting, and stomach pain.

The most common side effects of this medicine are muscle pain (myalgia), dryness in the mouth, swelling and heaviness of tongue (glossitis), and painful swelling and sores in the mouth (stomatitis). These are usually mild but let your doctor know if they bother you or last more than a few days. You can try using sugarless candies or lozenges to overcome any dryness or metallic taste in the mouth.
