Lithobid affects the flow of sodium through nerve and muscle cells in the body. Sodium affects excitation or mania.

Lithobid is used to treat the manic episodes of bipolar disorder (manic depression). Manic symptoms include hyperactivity, rushed speech, poor judgment, reduced need for sleep, aggression, and anger. This medicine also helps to prevent or lessen the intensity of manic episodes.

Lithobid may also be used for purposes not listed in this medication guide.

How should I take Lithobid?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Never use Lithobid in larger amounts, or for longer than prescribed. This medicine overdose can occur if you take only slightly more than a recommended dose.

Swallow the tablet whole and do not crush, chew, or break it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Taking Lithobid can make it easier for you to become dehydrated, especially if you have any vomiting or diarrhea, if you are outdoors in the sun, or if you exercise vigorously or sweat more than usual. Dehydration can increase some of the side effects of lithium.

Call your doctor if you are sick with a fever and vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking Lithobid, which may affect your dose needs. Do not change your dose or medication schedule without your doctor's advice.

Drink extra fluids each day to prevent dehydration.

It may take up to 3 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not begin to improve after 1 week of treatment.

You may need frequent blood tests.

If you need surgery, tell the surgeon ahead of time that you are using Lithobid.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Stop taking Lithobid and seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Early signs of lithium toxicity include: vomiting, diarrhea, tremors, loss of balance or coordination, drowsiness, or muscle weakness.

What should I avoid while taking lithium?

Avoid driving or hazardous activity until you know how Lithobid will affect you. Your reactions could be impaired.

Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Follow your doctor's instructions about the type and amount of liquids you should drink.

Do not change the amount of salt you consume in your diet. Changing your salt intake could change the amount of lithium in your blood.
