Cautions: This medication may not be suitable for everyone. To ensure safe and effective medical care, discuss any history or active case of any of the following conditions with your doctor when planning your treatment.

• Alcohol Abuse: Alcohol should not be used without the approval of your doctor during treatment, as it may cause the medication to be less effective. A long history of heavy alcohol use may indicate a weakened liver and a need for lower doses.
• Allergies: If you have had an allergic reaction to this drug, you will not be able to use it. If you develop one during treatment, you will have to discontinue use. Also inform your doctor if you have ever had an allergic reaction to any tricyclic antidepressant or Dilantin (phenytoin) in the past, as this may be an important factor in determining proper treatment. Any food or dye allergies should be mentioned as well, to ensure that the form of treatment you are prescribed doesn't cause a reaction.
• Anemia or Other Blood Cell Conditions: This medication may be unsuitable for you, or require lower dosing and more careful monitoring during treatment. Your doctor will have to make this decision on a case by case basis. This is of special concern if the condition is drug induced.
• Bone Marrow Conditions: This medication may be unsuitable for you, or require lower dosing and more careful monitoring during treatment. Your doctor will have to make this decision on a case by case basis. This is of special concern if the condition is drug induced.
• Depression or Other Psychiatric Disorder: Be sure to discuss treatment with your mental health care professional, and be aware that it may interact with certain treatments for these conditions. Latent psychosis may be revealed with Tegretol treatment.
• Diabetes: May increase levels of glucose in the urine, altering test results.
• Glaucoma: Your doctor will want to carefully monitor your condition during treatment.
• Heart or Coronary Disease: May worsen these conditions.
• Kidney or Liver Problems: This medication will need to be prescribed in much lower doses. Patients with active liver disease should not use Tegretol.
• Lupus: May be activated by Tegretol treatment. Individuals with the disease, or who are at high risk for it (i.e., have a family history of it) may want to discuss this with their doctor while planning treatment.
• Osteoporosis: May be worsened, as this drug reduces the availability of vitamin D to the body.
• Other Medication: Discuss all prescription and over the counter medication you use with your doctor. Inform all medical personnel that you take this medication, and carry identification to alert emergency personnel to your treatment if you should be unconscious.
• Pregnancy: If you plan to become pregnant, discuss this with your doctor. This drug is contraindicated for pregnancy due to increased risk of birth defects. The use of effective birth control during treatment is recommended, though Tegretol decreases the effectiveness of oral contraceptives. Breast feeding during treatment is not recommended.
• Thrombophlebitis: Inform your doctor of any history of this condition.
