Along with its needed effects, a medicine may cause some unwanted effects. Some side effects will have signs or symptoms that you can see or feel. Your doctor may watch for others by doing certain tests. Pemoline may cause some serious side effects, including liver problems. Also, medicines like pemoline, when used for a long time, have been reported to slow the growth rate of children.
Some doctors recommend medicine-free periods during treatment with pemoline.
Pemoline may also cause unwanted effects on behavior in children with severe mental illness. Although not all of these side effects may occur, if they do occur they may need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. The length of time this takes depends on the amount of medicine you were using and how long you used it. If you notice any other effects, check with your doctor.
