Penicillin Vk. 500 mg. Tabs
Generic Name:  Penicillin V. Potassium -- Oral Solids

DESCRIPTION

Penicillins are antibiotics used to treat a wide variety of bacterial infections.

INSTRUCTIONS FOR TAKING

This medication may be taken without regard to meals.  However, absorption is best if medication is taken on an empty stomach (one hour before or two-to-three hours after meals).

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 all of it 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 Dr. Thornton.

Notify Dr. Thornton 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 infections).

PRECAUTIONS

Tell Dr. Thornton if you have any other illnesses or any allergies, especially to penicillin or other antibiotics.

If pregnant or nursing, this medication should be used only after consulting with your obstetrician.

DRUG INTERACTIONS

This medication interferes with oral contraceptive (birth control pills).  If you are using oral contraceptives, please inform Dr. Thornton.  He will discuss other birth control methods to use while you are taking this drug.

Tell Dr. Thornton if you are using tetracycline, as your medicine may need to be changed.

ADDITIONAL INSTRUCTIONS

This medication has been prescribed for your current condition only.  Do not use it later for another infection or give it to someone else.  A different medication may be necessary in those cases.

If you miss a dose, take it as soon as remembered unless it is almost time for the next dose.  If it is nearly time for the next dose, skip the missed dose and resume your usual dosing schedule.  Do not "double-up" the dose.

Store this medication at room temperature away from moisture and sunlight.  Do not store in the bathroom.
