Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
if you are taking any other liquid medications, do not take them at the same time as carbamazepine liquid.
tell your doctor what herbal products you are taking, especially St. John's wort.
tell your doctor if you have or have ever had glaucoma; psychosis; or heart, kidney, thyroid, or liver disease.
you should know that carbamazepine may decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, injections, implants, or intrauterine devices). Use another form of birth control while taking carbamazepine. Tell your doctor if you have unexpected vaginal bleeding or think you may be pregnant while you are taking carbamazepine.
tell your doctor if you are pregnant or plan to become pregnant. Carbamazepine may harm the fetus. If you become pregnant while taking carbamazepine, call your doctor immediately.
do not breast-feed while you are taking carbamazepine.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking carbamazepine.
you should know that carbamazepine may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
remember that alcohol can add to the drowsiness caused by this medication.
you should know that your mental health may change in unexpected ways and you may become suicidal (thinking about harming or killing yourself or planning or trying to do so) while you are taking carbamazepine for the treatment of epilepsy, mental illness, or other conditions. A small number of adults and children 5 years of age and older (about 1 in 500 people) who took anticonvulsants such as carbamazepine to treat various conditions during clinical studies became suicidal during their treatment. Some of these people developed suicidal thoughts and behavior as early as one week after they started taking the medication. There is a risk that you may experience changes in your mental health if you take an anticonvulsant medication such as carbamazepine, but there may also be a risk that you will experience changes in your mental health if your condition is not treated. You and your doctor will decide whether the risks of taking an anticonvulsant medication are greater than the risks of not taking the medication. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: panic attacks; agitation or restlessness; new or worsening irritability, anxiety, or depression; acting on dangerous impulses; difficulty falling or staying asleep; aggressive, angry, or violent behavior; mania (frenzied, abnormally excited mood); talking or thinking about wanting to hurt yourself or end your life; withdrawing from friends and family; preoccupation with death and dying; giving away prized possessions; or any other unusual changes in behavior or mood. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.
