Important Information I Should Know About Morphine

Your doctor may want to gradually reduce your dose.

Do not stop taking morphine suddenly if you have been taking it continuously for more than 5 to 7 days. Stopping suddenly could cause withdrawal symptoms and make you very uncomfortable. Your doctor may want to gradually reduce your dose. Also, do not crush, chew, break, or open controlled-release forms of morphine such as Oramorph SR, Kadian, and MS Contin. Swallow them whole. They are specially formulated to release morphine slowly into your system. Breaking them would cause too much of the drug to be released into your blood at one time.

Morphine will cause drowsiness and fatigue. Avoid alcohol, sleeping pills, antihistamines, sedatives, and tranquilizers that may also make you drowsy except under the supervision of your doctor. It will also cause constipation. Drink plenty of water (six to eight full glasses a day) to lessen this side effect. Increasing the amount of fiber in your diet can also help to alleviate constipation. Never take more morphine than is prescribed for you. If your pain is not being adequately treated, talk to your doctor.

How Should I Take Morphine?

Take morphine 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 or with food or milk if it upsets your stomach.

Never take more of this medication than is prescribed for you. Too much morphine could be very harmful. To ensure that you get a correct dose, measure the liquid form of morphine 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.

Do not crush, chew, break, or open controlled-release forms of morphine such as Oramorph SR, Kadian, or MS Contin. Swallow them whole. They are specially formulated to release morphine slowly into your system. Breaking them would cause too much drug to be released into your blood at one time.

Use the suppositories rectally as directed by your doctor. If you do not know how to use them, ask you doctor, nurse, or pharmacist for instructions.

What Should I Avoid While Taking Morphine?

Avoid alcohol while taking morphine. Alcohol will greatly increase the drowsiness and dizziness caused by morphine and could be dangerous.
