Lanacin: Uses, Benefits, Dosage, Side Effects, Interactions

What is Lanacin?

Lanacin is a brand of Clindamycin HCL manufactured by Pharma International, it is used to treat certain types of bacterial infections, including infections of the lungs, skin, blood, female reproductive organs, and internal organs. Clindamycin is in a class of medications called lincomycin antibiotics.

Lanacin capsules are preferred by doctors for the treatment of the following conditions:

  • respiratory infections with streptococci, pneumococci, and staphylococci bacteria
  • empyema, anaerobic pneumonitis, or an abscess in the lung
  • blood poisoning
  • infections from anaerobic bacteria in the gut, resulting in peritonitis or an abscess in the abdomen
  • endometriosis, pelvic cellulitis, an abscess in the reproductive system, or a vaginal cuff infection

How Lanacin works

Lanacin capsules belong to the class of antibiotics known as lincosamide or lincomycin antibiotics. Lanacin capsules work by binding to the 50S subunit of the bacterial ribosome, which is responsible for the synthesis of bacterial proteins. This binding prevents the addition of new amino acids to the growing protein chain, thereby inhibiting bacterial protein synthesis.

By inhibiting protein synthesis, Lanacin prevents bacteria from growing and reproducing, leading to their eventual death. It is effective against a wide range of bacteria, including gram-positive and anaerobic bacteria.


How should I take Lanacin capsules?

Lanacin comes as a capsule to take by mouth. It is usually taken three to four times a day. The length of your treatment depends on the type of infection you have and how well you respond to the medication.

The typical dose of Lanacin is as follows:

Adults: The typical dose is 150 mg to 300 mg by mouth every 6 hours. For more severe infections, the dose is 300 mg to 450 mg by mouth every 6 hours.

Children: The dose will be based on your child’s weight. The typical dose is 8 mg/kg to 16 mg/kg of body weight per day, divided into three or four equal doses. For more severe infections, the dose is 16 mg/kg to 20 mg/kg of body weight per day, divided into three or four equal doses.

Take Lanacin capsules at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Lanacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Take the capsules with a full glass of water so that the medication will not irritate your throat.

You should begin to feel better during the first few days of treatment with Lanacin. If your symptoms do not improve or if they get worse, call your doctor.

Take Lanacin until you finish the prescription, even if you feel better. If you stop taking clindamycin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

Does Lanacin capsule work for a common cold or flu?

No. Lanacin capsule does not work for common cold or flu because it is an antibiotic that works against infections caused by bacteria only. The common cold and flu are viral infections, so Lanacin capsules won’t help treat these infections. Taking this medication for viral infections will lead to side effects and cause Lanacin capsules to not work as well for future infections. Discuss your symptoms with your healthcare provider to decide whether or not you need an antibiotic.
