    How To Use This Medicine

    Take Demerol exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

    Take each dose with a full glass of water. Take Demerol with food or milk if it causes stomach upset. To ensure that you get a correct dose, measure the syrup with a special dose-measuring spoon or cup, not with a regular tablespoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.

    Demerol is also available as an injection. Your healthcare provider will administer injectable Demerol. If you are using injectable Demerol at home, your healthcare provider will give you detailed instructions regarding preparation, administration, and storage of the medication.

    Never take more Demerol than is prescribed. If the pain is not being adequately treated, talk to your doctor.

    Demerol may be habit forming. Physical and/or psychological dependence can occur, and withdrawal effects are possible if the medication is stopped suddenly after prolonged or high-dose treatment. Do not stop taking Demerol suddenly without first talking to your doctor if you have been taking it continuously for more than 5 to 7 days. Your doctor may want to gradually reduce the dose.

    Demerol may cause constipation. Drink plenty of water (six to eight full glasses a day) to lessen this side effect. Increasing the amount of fiber in the diet can also help to alleviate constipation.

    Do not share this medication with anyone else. Store Demerol at room temperature away from moisture and heat.
