What should I know about methadone hydrochloride before taking it?

If you have a history of long QT syndrome (irregular heartbeat), asthma, chronic obstructive pulmonary disease (COPD), sleep apnea, liver or kidney disease, hypothyroidism, head injury, epilepsy, low blood pressure, Addison's disease, mental illness, or alcohol or drug addiction, you need to tell your doctor about your condition, as it may affect whether or not you should take methadone hydrochloride. You must not take more methadone hydrochloride than prescribed or take it more often than prescribed, as overdose and death can occur. You will need to pay close attention to your breathing and heartbeat while taking methadone hydrochloride and report any irregularities to your doctor. Methadone hydrochloride is most effective when taken on a regular schedule, as it is better at preventing pain rather than treating pain once you have it. You should avoid drinking alcohol while using methadone hydrochloride, as alcohol can increase drowsiness. Methadone hydrochloride can be addictive if you take it for longer than prescribed or in greater doses than prescribed. If you need any other medical care, including dental work, be sure to tell your doctor that you are taking methadone hydrochloride to avoid drug interactions.
