Product introduction

Halclor 250mg Capsule may be taken with or without food. You should take it regularly at evenly spaced intervals as per the schedule prescribed by your doctor. Taking it at the same time every day will help you to remember to take it. The dose will depend on what you are being treated for, but you should always complete a full course of this antibiotic as prescribed by your doctor. Do not stop taking it until you have finished, even when you feel better. If you stop taking it early, some bacteria may survive and the infection may come back. It will not work for viral infections such as flu or the common cold. Using any antibiotic when you do not need it can make it less effective for future infections.

The most common side effects of this medicine include rash, vomiting, nausea, diarrhea, and changes in liver function tests. These are usually mild but let your doctor know if they bother you or last more than a few days.

Before using it, you should tell your doctor if you are allergic to any antibiotics or have any kidney or liver problems. You should also let your doctor know all other medicines you are taking as they may affect, or be affected by this medicine. Pregnant and breastfeeding mothers should consult their doctor before using it. Avoid consuming alcohol while taking this medicine as it may cause unpleasant side effects like nausea, vomiting, sweating, anxiety, and palpitations.
