Dosage Of Lithium

Lithium comes as a tablet, capsule, extended-release (long-acting) tablet, and solution (liquid) to take by mouth. The tablets, capsules, and solution are usually taken three to four times a day. The extended-release tablets are usually taken two to three times a day. Take lithium at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lithium exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the extended-release tablet whole; do not split, chew, or crush it.

Your doctor may increase or decrease the dose of your medication during your treatment. Follow these directions carefully.

Lithium may help to control your condition but will not cure it. It may take 1 to 3 weeks or longer for you to feel the full benefit of lithium. Continue to take lithium even if you feel well. Do not stop taking lithium without talking to your doctor.

Other

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
