What is skenan LP (morphine) used for?

Skenan LP is commonly used for treating moderate to severe pain. Morphine is not used for treating short-term pain just after surgery unless you were already taking morphine before the surgery.

The extended-release form of this medicine is for around-the-clock treatment of pain. This form of morphine is not for use on an as-needed basis for pain.

How should I take skenan LP (morphine)?

Morphine can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never take morphine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Stop taking all other around-the-clock narcotic pain medications when you start taking morphine.

Do not crush, chew, or break an extended-release tablet. Swallow it whole to avoid exposure to a potentially fatal dose.

Take the medicine at the same time each day.

Do not stop using morphine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

Never crush or break a morphine pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death with the misuse of morphine and similar prescription drugs.

Skenan LP is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store skenan LP in the bathroom or the freezer. There may be different brands of skenan LP that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.
