Take penicillin V exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
You may take penicillin V with or without food.
To be sure penicillin V is helping your condition, your blood may need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled visits to your doctor.
Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Take penicillin V for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Penicillin V will not treat a viral infection such as the common cold or flu. Do not give this medicine to another person, even if they have the same symptoms you do.
Penicillin V can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are using penicillin V.
Store penicillin V tablets at room temperature away from moisture, heat, and light. Store liquid penicillin V in a refrigerator but do not allow it to freeze. Throw away any liquid that has not been used within 14 days after it was mixed at the pharmacy.
