When should it be used?

Follow the instructions on your prescription label carefully. Take ampicillin four times a day, take a dose every six hours.

How should it be used?

Ampicillin comes in capsules, chewable tablets, liquid, and pediatric drops to be taken orally, and in injection form. We have chosen the form that is best for you, and your prescription label tells you how much to take at each dose. Ampicillin should be taken on an empty stomach, one hour before or two hours after meals. Capsules should be taken with a full glass of water. The liquid and pediatric drops should be shaken well before each use to mix the medication evenly. Use the bottle dropper to measure the dose of pediatric drops. You may obtain a specially marked measuring spoon from your pharmacist to be sure of an accurate dose of the liquid. Tablets should be crushed or chewed thoroughly before they are swallowed. Ask us or your pharmacist any questions you have about refilling your prescription.
