Lithmax is a medication that is primarily used for the treatment of bipolar disorder, specifically for managing manic episodes. It contains lithium carbonate as its active ingredient.

Lithium is classified as a mood stabilizer and helps to control the symptoms of mania, such as reduced need for sleep.

Use and Dosage

There are different brands of this medication available. They may not have the same effects. Do not change brands without asking your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually 2-3 times daily. Take lithium with or immediately after meals to lessen stomach upset. Do not crush or chew this medication. Doing so can release the entire drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

Drink 8 to 12 glasses (8 ounces or 240 millilitres each) of water or other fluid each day and eat a healthy diet with normal amounts of salt (sodium) as directed by your doctor or dietician while taking this medication. Large changes in the amount of salt in your diet may change your lithium blood levels. Do not change the amount of salt in your diet unless your doctor tells you to do so.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. The dosage is based on your medical condition, lithium blood levels, and response to treatment. This medication works best if the amount of the drug in your body is kept at a constant level. Take this drug at evenly spaced intervals.

This medication must be taken exactly as prescribed. Keep taking lithium even if you feel well. Do not stop taking this drug without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Consult your doctor or pharmacist for more details.

Tell your doctor if your condition does not improve or if it worsens. It may take 1 to 3 weeks to notice improvement in your condition.

  • Before taking lithium, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
  • Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart disease, kidney disease, urinary problems (such as difficulty urinating), underactive thyroid (hypothyroidism), seizures, Parkinson’s disease, leukemia, severe dehydration, any infection with high fever, a certain skin disorder (psoriasis).
  • Lithium treatment may rarely reveal an existing condition that affects the heart rhythm (Brugada syndrome). Brugada syndrome is an inherited, life-threatening heart problem that some people may have without knowing it. It can cause a serious (possibly fatal) abnormal heartbeat and other symptoms (such as severe dizziness, fainting, and shortness of breath) that need medical attention right away. Brugada syndrome may cause death suddenly. Before starting lithium treatment, tell your doctor if you have any of the following risk factors: Brugada syndrome, unexplained fainting, family history of certain heart problems (Brugada syndrome, sudden unexplained death before 45 years old).
  • This drug may make you dizzy, drowsy, or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).
  • If heavy sweating or severe diarrhea occurs, check with your doctor right away how to best continue taking lithium. Take care in hot weather or during activities that cause you to heavily sweat such as during hot baths, saunas, or exercise.
  • Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
  • Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using lithium. Lithium may harm an unborn baby. However, since untreated mental/mood problems (such as bipolar disorder) can harm a pregnant woman and her unborn baby, do not stop taking this medication unless directed by your doctor. Instead, ask your doctor if a different medication would be right for you. If you are planning pregnancy, become pregnant, or think you may be pregnant, talk to your doctor right away about the risks and benefits of this medication.
