Before Using acetylcysteine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For acetylcysteine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to acetylcysteine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Although there is no specific information comparing use of acetylcysteine in children with use in other age groups, acetylcysteine is not expected to cause different side effects or problems in children than it does in adults.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of acetylcysteine in the elderly with use in other age groups.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking acetylcysteine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using acetylcysteine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other Medical Problems
The presence of other medical problems may affect the use of acetylcysteine. Make sure you tell your doctor if you have any other medical problems, especially:
- Asthma—Acetylcysteine may make the condition worse
- Decreased ability to cough—The mucus may have to be removed by suctioning
Proper Use of acetylcysteine
Use acetylcysteine only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of side effects.
If you are using acetylcysteine at home, make sure you understand exactly how to use it. If you have any questions about this, check with your doctor.
After using acetylcysteine, try to cough up the loosened or thinned mucus. If this does not work, it may have to be suctioned out. This will prevent too much mucus from building up in the lungs. If you have any questions about this, check with your doctor.
The dose of acetylcysteine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of acetylcysteine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
