PENICILLIN V POTASSIUM - ORAL LIQUID

(pen-ih-SILL-in VEE poh-TASS-ee-um)

COMMON BRAND NAME(S): Ledercillin VK, Pen-Vee K, Veetids

Uses

Penicillin is an antibiotic used to treat a wide variety of bacterial infections.

How To Use

This medication may be taken without regard to meals. However, absorption is best if the medication is taken on an empty stomach (1 hour before or 2 to 3 hours after meals). Shake liquid well before using. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Do this by taking the medication at evenly spaced intervals throughout the day and night. Continue to take this medication until the full prescribed amount is finished even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow resulting in a relapse of the infection.

Side Effects

This medication may cause stomach upset, diarrhea, nausea, and vomiting during the first few days as your body adjusts to the medication. If these symptoms persist or become severe, inform your doctor. Notify your doctor immediately if an allergic reaction occurs while taking this medication. Symptoms include: difficulty breathing, skin rash, hives or itching. Use of this medication for prolonged or repeated periods may result in a secondary infection (e.g., oral, bladder or vaginal yeast infection). If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Tell your doctor if you have: other illnesses, allergies (especially to penicillin or other antibiotics). This medication should be used only if clearly needed during pregnancy.
