How does clindamycin work?

This drug works by preventing the growth of bacteria. It does so by restricting and stopping the multiplication of bacteria. This keeps the bacteria from reproducing further as well as prevent the repair of their genetic material, i.e., DNA.

Clindamycin should not be used for the common cold and flu and other similar viral infections because it will not be effective. Using an antibiotic when not needed can reduce its effectiveness for future uses as the pathogen (disease-causing organism) may become resistant to it. As a result, they undergo mutations and introduce genes that will keep them unaffected by the action of the said antibiotic.


How to use clindamycin

Clindamycin is a medicinal drug and should only be taken with a doctor’s recommendation. It must be taken orally with water. You may choose to take the medicine with or without a meal, but you may also choose to follow your doctor’s directions. The dosage may vary according to the patient’s medical health, weight, and age but it usually tends to be 3-4 times a day at equally spaced intervals. Swallow the tablet whole; do not chew, break or bite it as this may increase the side effects.

Do not alter dosages or overdose as it may lead to serious side effects. Take clindamycin regularly as per your doctor’s recommendation for the best of results.



  • Do not use Clindamycin if you are allergic to it or any of its ingredient.
  • Not suitable for individuals under 18 years.
  • Do not use it if you are pregnant or breastfeeding as it may harm the child.
