These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
Follow the treatment program closely. Report any side effects or withdrawal symptoms to your health care provider. Levomethadyl has a slow onset of action and may take several hours to see the first effect and a several days to determine your exact dose. Since it takes 7—10 days for you to feel the full effects of levomethadyl, do not take other drugs that have similar effects to levomethadyl, especially alcohol, antidepressants, or other opiate drugs. Do not suddenly stop taking levomethadyl.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how levomethadyl affects you. Alcohol can increase possible drowsiness, dizziness, confusion, and can affect your breathing. Avoid alcohol while taking levomethadyl.
Levomethadyl will cause constipation. Make sure to take a laxative and/or stool softener while taking levomethadyl. Try to have a bowel movement every 2—3 days, at least. If you do not have a bowel movement for 3 days or more, call your prescriber or health care professional. They may recommend using an enema or suppository to help you move your bowels.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Visit the dentist regularly.
If you are going to have surgery or dental work, or will be hospitalized, tell your prescriber or health care professional that you are taking levomethadyl and give them the name of your treatment center.
