Drink 8 to 12 glasses (8 ounces/240 milliliters 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.
The dosage is based on your medical condition, lithium blood levels, and response to treatment. Children's dosage is also based on weight. For the best effect, take this medication regularly at evenly spaced times. To help you remember, take this medication at the same times every day.
If you are taking the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.
This medication must be taken exactly as prescribed. Keep taking this medication 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.

It is very important to have the right amount of lithium in your body. Too much lithium may lead to unwanted effects such as nausea, diarrhea, shaking of the hands, dizziness, twitching, seizures, trouble speaking, confusion, or increase in the amount of urine. Tell your doctor right away if these effects occur.
There is only a small difference between the correct amount of lithium and too much lithium. It is important that your doctor monitor you closely during treatment. Keep all medical and lab appointments while you are taking lithium.
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 (such as propylene glycol), 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, dehydration, any infection with high fever, a certain skin disorder (such as 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, 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 or 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 sweat heavily, such as during hot baths, saunas, or exercise.
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.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Other medications can affect the removal of lithium from your body, which may affect how lithium works. Examples include ACE inhibitors (such as captopril, enalapril), ARBs (such as losartan, valsartan), NSAIDs (such as celecoxib, ibuprofen), "water pills" (diuretics such as hydrochlorothiazide, furosemide), other drugs for mental/mood conditions (such as chlorpromazine, haloperidol, thiothixene), among others. Your doctor may need to adjust your dose of lithium if you are on these medications.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Some examples are street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (such as SSRIs like fluoxetine/paroxetine, SNRIs like duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
Eat a normal diet with an average amount of sodium. Ask your doctor or dietician for more details.
