Uses
What Is Clindamycin?
Clindamycin is an antibiotic effective against bacterial infections that belongs to the lincosamide class of antibiotics. Three available salts of clindamycin include clindamycin phosphate, clindamycin hydrochloride, and clindamycin palmitate. These salts come in various forms such as liquid, capsules, and injectable solutions. The FDA approved clindamycin in 1970, marking its long-standing use in medicine.
Types of Clindamycin
The two primary types are clindamycin phosphate and clindamycin hydrochloride, each with specific applications and formulations:
Clindamycin Phosphate
Clindamycin phosphate is commonly used in topical and injectable forms. It is often prescribed for treating severe acne, bacterial vaginosis, and certain types of bacterial infections that require intravenous administration. This form is known for its effectiveness in penetrating tissues and providing targeted antibacterial action.
Clindamycin Hydrochloride
Clindamycin hydrochloride is typically available in oral forms such as capsules and solutions. It is used to treat a variety of bacterial infections, including respiratory tract infections, skin infections, and infections of the internal organs. This form is absorbed through the gastrointestinal tract and is effective in reaching systemic infections.
What Is Clindamycin Used For?
Clindamycin is a versatile antibiotic used to treat a variety of bacterial infections. It should only be used for infections confirmed or strongly suspected to be caused by susceptible bacteria to help prevent the development of drug-resistant bacteria, and to maintain the drug’s effectiveness.
Respiratory Infections
In both adults and children, clindamycin is effective against serious infections caused by anaerobic bacteria and certain strains of streptococci, pneumococci, and staphylococci, especially when other antibiotics like erythromycin are not suitable. It is commonly used to treat lower respiratory tract infections such as pneumonia, empyema, and lung abscesses.
Skin and Soft Tissue Infections
Clindamycin is effective for skin and soft tissue infections, including those caused by Streptococcus pyogenes, Staphylococcus aureus, and anaerobes. Topically, clindamycin 1% is often prescribed to manage severe acne.
Gynecological Infections
Clindamycin is used to treat gynecological infections like endometritis, tubo-ovarian abscesses, pelvic cellulitis, and post-surgical vaginal cuff infections.
Intra-Abdominal Infections
For intra-abdominal infections, clindamycin is effective against conditions like peritonitis and intra-abdominal abscesses.
Septicemia
Clindamycin is also used to treat septicemia caused by susceptible strains of Staphylococcus aureus, streptococci (excluding Enterococcus faecalis), and anaerobes.
Bone and Joint Infections
In cases of bone and joint infections, such as acute hematogenous osteomyelitis, clindamycin is used both as a primary treatment and as an adjunct in surgical management of chronic infections.
Limitations
It’s important to note that clindamycin does not penetrate the cerebrospinal fluid adequately, and should not be used to treat meningitis. Always consult with your healthcare provider to determine if clindamycin is the right antibiotic for your specific infection.

Clindamycin Side Effects
Common Side Effects
Clindamycin can cause several common gastrointestinal symptoms. These include nausea, vomiting, and diarrhea, and some patients report feeling an upset stomach after taking the medication. Some may even experience abdominal pain, cramps, vaginal itching, or discharge.
A metallic taste is another potential side effect of clindamycin. This unusual sensation can be bothersome for some individuals, but it often goes away after stopping the medication. If you experience any discomfort, be sure to inform your healthcare provider. Here’s a full list of the common side effects of clindamycin:
Nausea
Vomiting
Diarrhea
Abdominal pain
Rash
Vaginal itching and discharge
Severe Side Effects
Severe side effects from clindamycin are rare but can occur. One serious reaction is clindamycin toxicity, which can lead to severe colitis. This condition causes inflammation in the colon and can result in severe diarrhea, abdominal pain, and fever. If you experience these symptoms, seek medical attention immediately.
Another significant concern involves box warnings associated with clindamycin use. The FDA has issued warnings about the risk of antibiotic-associated colitis. This condition can develop when the normal bacteria in the gut are disrupted. Patients who have a history of gastrointestinal issues should use clindamycin with caution.
If you experience any of the following side effects, urgently inform your doctor and consider reporting the effects to the FDA by calling 1-800-FDA-1088:
Severe allergic reactions (anaphylaxis)
Clostridium difficile-associated diarrhea (CDAD)
Severe skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis)
Liver dysfunction
Blood disorders (leukopenia, thrombocytopenia)
Severe abdominal pain or cramping

Complete the Course
Use clindamycin for the full prescribed length of time, even if your symptoms improve quickly. Missing doses may lead to the development of antibiotic-resistant infections. Clindamycin will not treat viral infections such as the flu or a common cold.
Storage Instructions
Room Temperature: Store clindamycin at room temperature, away from moisture and heat. Protect the injectable form from high heat.
Oral Liquid: Do not refrigerate the oral liquid. Discard any unused oral liquid after 2 weeks.
By following these guidelines, you can ensure the effectiveness of clindamycin and reduce the risk of side effects. Contact your doctor if you have any questions or concerns.
Missed Dose
If you miss a dose of clindamycin, take it as soon as you remember unless it is almost time for your next scheduled dose; in that case, skip the missed dose and continue with your regular dosing schedule. Avoid taking an extra dose to compensate for the one you missed, as this may elevate the likelihood of experiencing side effects. Consistently taking your medication as prescribed is crucial for effectively treating your infection and preventing antibiotic resistance.
Interactions
Antibiotics to Avoid
Avoid using clindamycin concurrently with erythromycin, as both are antibiotics that can interfere with each other’s effectiveness.
Other Medications
Clindamycin can interact with a variety of other medications, including prescription drugs, over-the-counter medicines, vitamins, and herbal supplements. It’s important to inform all your healthcare providers about any medications you are currently taking or plan to start or stop.
Neuromuscular Blocking Agents
Clindamycin has properties that can enhance the effects of neuromuscular blocking agents like succinylcholine, rocuronium, and vecuronium. Use these combinations with caution.
Enzyme Interactions
Clindamycin is primarily metabolized by the CYP3A4 enzyme and, to a lesser extent, by CYP3A5. This means that strong or moderate inhibitors of these enzymes, such as clarithromycin, nefazodone, itraconazole, ketoconazole, atazanavir, darunavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, and tipranavir, should be used with caution. Similarly, inducers of these enzymes, like phenobarbital, phenytoin, rifampicin, St. John’s Wort, and glucocorticoids, can reduce clindamycin’s effectiveness and should also be used cautiously.
