Dolophine

Pronunciation: METH-a-done

Dolophine may cause severe and sometimes fatal heart and breathing problems. These problems may occur some time after you take a dose. Tell your doctor right away if you develop any new or worsening symptoms such as slowed or shallow breathing or irregular heartbeat. Your doctor will perform heart and lung function tests to check for side effects while you take Dolophine. Keep all doctor and laboratory appointments. Talk with your doctor and be sure you understand the risks and benefits of using Dolophine.

Do not take more than the recommended dose or take Dolophine more often than prescribed. This can lead to overdose and possible death.

Dolophine is used for:

Treating moderate to severe pain that is not relieved by other pain medicines. It is also used in treating narcotic addiction as part of a treatment program. It may also be used for other conditions as determined by your doctor.

Dolophine is a narcotic analgesic. It works by acting on opiate pain receptors in the brain and on smooth muscle to provide pain relief.

Do NOT use Dolophine if:

• you are allergic to any ingredient in Dolophine


• you have slowed breathing or severe asthma, or if you are having an asthma attack


• you have a stomach or bowel blockage or certain severe bowel problems (eg, paralytic ileus)


• you have diarrhea caused by food poisoning or antibiotic use


• you are taking sodium oxybate (GHB)


• if you have taken a monamine oxidase inhibitor type B (MAOI-B) (eg, rasagiline, selegiline) within the last 14 days

Contact your doctor or health care provider right away if any of these apply to you.
