How to Use lithium
Take this medicine by mouth with a glass of water. Follow the directions on the prescription label. Take after a meal or snack to avoid stomach upset. Take your doses at regular intervals. Do not take your medicine more often than directed. The amount of this medicine you take is very important. Taking more than the prescribed dose can cause serious side effects. Do not stop taking except on the advice of your doctor or health care professional.
Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed. While this drug may be prescribed for children as young as 12 years for selected conditions, precautions do apply.
They need to know if you have any of these conditions:
- Brugada Syndrome
- dehydration (diarrhea or sweating)
- heart or blood vessel disease
- kidney disease
- low level of salt in the blood, or on a low salt diet
- an unusual or allergic reaction to lithium, other medicines, foods, dyes, or preservatives

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
Visit your doctor or health care professional for regular checks on your progress. It can take several weeks of treatment before you start to get better.
The amount of salt (sodium) in your body influences the effects of this medicine, and this medicine can increase salt loss from the body. Eat a normal diet that includes salt. Do not change to salt substitutes. Avoid changes involving diet, or medications that include large amounts of sodium like sodium bicarbonate. Ask your doctor or health care professional for advice if you are not sure.
Drink plenty of fluids while you are taking this medicine. Avoid drinks that contain caffeine, such as coffee, tea and colas. You will need extra fluids if you have diarrhea or sweat a lot. This will help prevent toxic effects from this medicine. Be careful not to get overheated during exercise, saunas, hot baths, and hot weather. Consult your doctor or health care professional if you have a high fever or persistent diarrhea.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.
Keep out of the reach of children.
Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F). Throw away any unused medicine after the expiration date.
