GENERIC NAME: PENICILLINS - INJECTION
USES: Penicillins are antibiotics used to treat a wide variety of bacterial infections.
HOW TO USE: This medication must be used as directed by your doctor. Clean area before administering. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Do this by using the medication at evenly spaced intervals throughout the day and night. Continue to use 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 mild diarrhea, stomach upset, 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 you develop: bloody urine, fever, unusual bleeding or bruising, yellow eyes or skin, unusual tiredness or weakness. This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a resistant bacteria. This condition may occur while receiving therapy or even weeks after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, or blood/mucus in your stool. A serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching, swelling, dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
