Use exactly as directed by your care team. Do not take more than the recommended dose. You may develop tolerance to this medication if you take it for a long time. Tolerance means that you will get less cough relief with time. Tell your care team if your symptoms do not improve or if they get worse.
If you have been taking this medication for a long time, do not suddenly stop taking it because you may develop a severe reaction. Your body becomes used to the medication. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a medication for a nonmedical reason. If your care team wants you to stop the medication, the dose will be slowly lowered over time to avoid any side effects.
There are different types of narcotic medications (opiates). If you take more than one type at the same time or if you are taking another medication that also causes drowsiness, you may have more side effects. Give your care team a list of all medications you use. Your care team will tell you how much medication to take. Do not take more medication than directed. Call emergency services for help if you have problems breathing or unusual sleepiness.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medication affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medication. Avoid alcoholic drinks.
This medication can make you more sensitive to the sun. Keep out of the sun. If you cannot avoid being in the sun, wear protective clothing and use sunscreen. Do not use sun lamps or tanning beds/booths.
This medication will cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your care team.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your care team if the problem does not go away or is severe.
This medication may cause dry eyes and blurred vision. If you wear contact lenses, you may feel some discomfort. Lubricating drops may help. See your eye care team if the problem does not go away or is severe.
