Clindamycin Hydrochloride: Mechanisms of Action and Adverse Effects

Oct 22,2024

Clindamycin is an antibiotic that fights bacteria in the body. Clindamycin is used to treat serious infections caused by bacteria.

Clindamycin is usually available as one of three salts: clindamycin phosphate, clindamycin hydrochloride, or clindamycin nicotinamide. These salt forms are all prodrugs of clindamycin but once inside the body or applied to the skin, they are rapidly converted to active clindamycin by hydrolysis. All three salt forms of clindamycin: clindamycin phosphate, clindamycin hydrochloride, and clindamycin nicotinamide have the same antimicrobial spectrum and effectiveness.

What is clindamycin hydrochloride?

Clindamycin hydrochloride is a salt of clindamycin that is usually used for oral formulations of clindamycin.

Clindamycin hydrochloride is a prodrug of clindamycin that is rapidly converted to active clindamycin once inside the body.

Clindamycin hydrochloride has the same antimicrobial spectrum and effectiveness as clindamycin phosphate, clindamycin nicotinamide, and clindamycin.

What is Clindamycin Hydrochloride used to treat?

Clindamycin Hydrochloride may be used to treat a wide range of infections, although it should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria to reduce the development of drug-resistant bacteria and to maintain its effectiveness.

Infections Clindamycin Hydrochloride treats in adults and children include serious:

  • Infections caused by susceptible anaerobic bacteria

  • Infections due to susceptible isolates of streptococci, pneumococci, and staphylococci, if a less toxic alternative (such as erythromycin) is not suitable

  • Lower respiratory tract infections including pneumonia, empyema, and lung abscess caused by susceptible isolates of anaerobes, Streptococcus pneumoniae, other streptococci (except Enterococcus faecalis), and Staphylococcus aureus in adults and children

  • Skin and skin structure infections caused by susceptible isolates of Streptococcus pyogenes, Staphylococcus aureus, and anaerobes in adults and children

  • Gynecological infections including endometritis, nongonococcal tubo-ovarian abscess, pelvic cellulitis, and postsurgical vaginal cuff infection caused by susceptible anaerobes in adults and children

  • Intra-abdominal infections including peritonitis and intra-abdominal abscesses caused by susceptible anaerobic organisms in adults and children

  • Septicemia caused by susceptible isolates of Staphylococcus aureus, streptococci (except E. faecalis), and susceptible anaerobes in adults and children

  • Bone and joint infections including acute hematogenous osteomyelitis caused by susceptible isolates of S. aureus and as adjunctive therapy in the surgical treatment of chronic bone and joint infections due to susceptible organisms in adults and children.

Clindamycin Hydrochloride does not adequately penetrate the cerebrospinal fluid and should NOT be used to treat meningitis.

Clindamycin Hydrochloride side effects

The most common clindamycin side effects include:

  • nausea or vomiting

  • stomach (abdominal) pain

  • mild skin rash

  • vaginal itching or discharge.

Clindamycin Hydrochloride may also cause a metallic taste in your mouth. 

Serious side effects and warnings

Clindamycin Hydrochloride carries a Boxed Warning for Clostridium difficile-associated diarrhea (CDAD).

Clindamycin can cause diarrhea, which may range in severity from mild to fatal colitis. Diarrhea associated with clindamycin use is sometimes caused by an overgrowth of dangerous Clostridium difficile bacteria in the large intestine. Seniors especially should be monitored for diarrhea. If you have diarrhea that is watery or bloody, stop using clindamycin and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to. Seek urgent medical attention.
