What special precautions should I follow?   

Before taking clindamycin,

• tell your doctor and pharmacist if you are allergic to clindamycin, tartrazine (a yellow dye in some processed foods and drugs), or any other drugs.
• tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins. If you are using topical clindamycin, ask your doctor for advice on using other acne medications (e.g., benzoyl peroxide) and cosmetics. Some cosmetics make acne worse and interfere with the effectiveness of this medication.
• tell your doctor if you have or have ever had gastrointestinal, liver, or kidney disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using clindamycin, call your doctor.

What should I do if I forget a dose?   

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and take any remaining doses for that day at evenly spaced intervals. Do not take a double dose to make up for a missed one. Do not apply a missed topical dose.
