General Advice
- Capsules and oral solution
- Administer without regard to meals but administer with food if GI upset occurs.
- Administer capsules with a full glass of water to reduce esophageal irritation.
- Administer prescribed dose of oral solution using dosing spoon or dosing syringe.
- Injection
- For IV infusion or IM administration only. Not for intradermal, subcutaneous, or intra-arterial administration.
- To minimize injection-site reactions, administer by deep IM injection and avoid prolonged use of indwelling IV catheters.
- Do not administer undiluted solution by IV bolus. Infuse over at least 10 to 60 min. Follow manufacturer's guidelines for recommended dilutions and infusion rates.
- Follow manufacturer's recommendations for reconstituting clindamycin when using the ADD-Vantage system.
- Do not administer if particulate matter, cloudiness, or discoloration noted. Gently squeeze premixed IV solution bag before administration. Discard if leaks are detected.
- Do not add other drugs to the clindamycin infusion bag.
- Do not use plastic IV containers in series connections because of risk of air embolism.
- Topical gel, solution, and lotion
- For topical use only. Not for ophthalmic, vaginal, or oral administration.
- Cleanse areas to be treated before applying medication.
- Shake lotion well just before use.
- If using topical solution pledget, remove pledget from foil just before use. Do not use if seal is broken. Discard pledget after single use.
- Topical solution contains an alcohol base and will cause burning and irritation if applied to sensitive surfaces. Avoid contact with the eyes, mucous membranes, and abraded skin. If accidental contact occurs, rinse with large amounts of cool tap water.
- Do not use any other topical acne medication unless ordered by health care provider.
- Do not dispense foam directly onto hands or face; foam will melt on contact with warm skin. Dispense amount directly onto cap or on a cool surface. If the can seems warm or the foam seems runny, run the can under cold water.
- Vaginal cream and ovules
- For intravaginal use only. Not for ophthalmic, dermal, or oral administration.
- Administer Cleocin vaginal cream and ClindaMax vaginal cream using disposable applicator provided with medication.
- Administer Clindesse vaginal cream using the prefilled disposable applicator.
- Administer suppository using reusable applicator.
- If accidental contact of vaginal cream with the eye(s) occurs, rinse the eye(s) with large amounts of cool tap water.
Storage/Stability
Store capsules, oral solution, and injection at controlled room temperature (68° to 77°F). Do not refrigerate oral solution (causes thickening), and discard any unused oral solution after 14 days. Store topical gel, lotion, foam, and solution at controlled room temperature (68° to 77°F). Store Clindagel gel, Clindets , and ClindaMax gel and lotion between 59° and 86°F. Protect from freezing.

Precautions
WarningsThese agents can cause severe and possibly fatal colitis, characterized by severe persistent diarrhea, severe abdominal cramps, and possibly the passage of blood and mucus. When significant diarrhea occurs, discontinue the drug or, if necessary, continue only with close observation of the patient. Large bowel endoscopy is recommended. Promptly manage moderate to severe cases with fluid, electrolyte, and protein supplements as indicated, and treatment with an antibacterial agent clinically effective against Clostridium difficile colitis. Reserve for serious infections in which less toxic antimicrobial agents are inappropriate. Do not use in patients with nonbacterial infections (most upper respiratory tract infections). |
MonitorBlood count/Renal function/Liver enzymesEnsure that blood counts, liver enzymes, and renal function are determined periodically during prolonged therapy. Response to therapyMonitor patient's response to therapy. Notify health care provider if infection does not appear to improve or worsens. Side effectsMonitor patient for GI, DERM, general body side effects, and signs of superinfection. Report to health care provider if noted and significant. Immediately report severe diarrhea, diarrhea containing blood or pus, or severe abdominal cramping. |
