Antibiotics - Lincosamides: Nursing pharmacology

Lincosamides are a class of antibiotics used to treat severe infections caused by gram positive and anaerobic bacteria. The lincosamide family of antibiotics includes both clindamycin and lincomycin, however, lincomycin has been widely replaced by clindamycin in almost all of its uses.Now, clindamycin is most often used to treat skin and soft tissue infections caused by staphylococci and streptococci.

It can be active against community-acquired strains of methicillin resistant Staphylococcus aureus, or MRSA for short, an increasingly common cause of cutaneous infections.

Additionally, clindamycin is indicated for the treatment of anaerobic infections caused by Bacteroides species and other anaerobes that often participate in mixed flora infections.

Consequently, it is often used in combination with cephalosporins or aminoglycosides to treat penetrating wounds of the abdomen and gut, infections originating in the female reproductive tract, and lung abscesses.

Finally, clindamycin may be used for the prophylaxis of endocarditis in clients with underlying valvular heart disease, as well as to treat Pneumocystis jirovecii pneumonia in clients with HIV infection.For the treatment of systemic infections, clindamycin can be administered orally or by intravenous or intramuscular injection.

Additionally, clindamycin can be used topically for the treatment of acne and rosacea, as well as intravaginally for the treatment of bacterial vaginosis.All right now, once administered, clindamycin targets the 50S ribosomal subunit of the bacteria, thereby inhibiting protein synthesis and ultimately limiting the growth of bacteria.

Although clindamycin has a primarily bacteriostatic effect, it can also act as a bactericidal antibiotic at higher concentrations.

Since clindamycin tastes extremely bitter, it is not commonly prescribed to children. The most common side effects of clindamycin include gastrointestinal disturbances like nausea, vomiting, diarrhea, and abdominal cramps.

Long-term use can disrupt the normal intestinal flora, which can allow certain bacteria like Clostridioides difficile to survive and overgrow within the gastrointestinal tract, rarely but potentially leading to Clostridioides difficile infection or CDI for short.

If CDI involves the colon, it is known as pseudomembranous colitis, and that’s a boxed warning for clindamycin. Another severe side effect of clindamycin is the potential for serious hypersensitivity reactions, such as Stevens-Johnson syndrome or exfoliative dermatitis.

Clients on intravenous or intramuscular administration can experience induration, irritation, or abscess formation at the injection site.

Finally, with intravaginal administration, there may be redness, burning, and itching, as well as increased risk of vaginal candidiasis.As far as contraindications go, clindamycin should be stopped if the client develops pseudomembranous colitis.

Additionally, it should be used with caution in clients who are pregnant or breastfeeding, as well as in clients with gastrointestinal or hepatic disease.All right, when caring for a client who has been prescribed a lincosamide like clindamycin for a skin abscess after incision and drainage, first perform a baseline assessment of the affected area, making note of the size of the abscess, redness, warmth, swelling, odor, and presence of pain, as well as the amount and color of drainage.

Then, review your client’s recent laboratory results, including CBC, hepatic and renal function, as well as culture and sensitivity results.

Next, explain to your client how the medication works to treat their infection by stopping the growth of the bacteria. Then, if your client is prescribed oral clindamycin, advise them to take their medication four times a day, with at least 8 ounces of water to avoid irritation of the esophagus.

Also, let them know that taking their medication with food helps avoid a bitter taste in the mouth. If they’re prescribed a liquid form, instruct them to shake the oral solution well before use, as well as how to use the provided oral solution dispenser.

Be sure to emphasize the importance of completing the full course of their medication, even if the symptoms of their infection start to resolve.

Then, inform your client about some side effects they could experience, such as nausea and vomiting. Prompt them to notify their healthcare provider right away if they experience symptoms of CDI, such as abdominal pain or severe and bloody diarrhea.

All right, before administering intravenous clindamycin, be sure to confirm a patent IV is in place. As the medication infuses, continue to monitor your client’s IV site closely for any signs of infiltration.

In addition, monitor your client for signs of a hypersensitivity reaction, including difficulty swallowing, shortness of breath, and an unusual rash; and if your client develops bloody diarrhea during therapy, immediately notify the healthcare provider and be prepared to send a specimen to the lab for Clostridioides difficile.

Finally, during treatment with a lincosamide like clindamycin, be sure to monitor for the development of side effects, and evaluate your client for the desired therapeutic response to the medication by assessing your client’s wound for signs of infection resolution, which can present as a decrease in drainage, redness, or pain.

All right, as a quick recap… Lincosamides are a class of antibiotics that include clindamycin and lincomycin, which can be used to treat severe infections caused by gram positive and anaerobic bacteria, such as skin and soft tissue, penetrating wounds to abdomen, lung abscesses, pneumonia, female reproductive tract infections, and endocarditis prophylaxis.

Clindamycin can be administered orally, intramuscularly, or intravenously, as well as topically in cases of rosacea and acne, or intravaginally for bacterial vaginosis.

Side effects of clindamycin include gastrointestinal disturbances like nausea and vomiting, rashes or hypersensitivity reactions, and has a boxed warning for Clostridioides difficile infection.When caring for a client receiving a lincosamide, nursing considerations include performing a baseline assessment, monitoring for side effects, and evaluating for the desired therapeutic response.

Client teaching is focused on safe self-administration, as well as learning to recognize side effects, and when to notify the
