Bipolar Side Effects of Lithium

Lithium is the drug with the longest history of treating bipolar disorder, and it remains a popular choice today. Some people who use lithium experience no side effects; however, many others do. Here are the most common side effects when treating bipolar disorder with lithium.

Thirst

• Lithium is a salt, so it may increase thirst and feelings of dry mouth. You can treat these by drinking more water, chewing gum or sucking hard candy.

Nausea

• Some people who take lithium may notice mild nausea. If you have taken lithium for a while without nausea, but nausea appears later, consult a physician.

Weight Gain

• Lithium causes you to retain water, which can cause weight gain, bloating and swelling in your ankles.

Tremor

• Some people on lithium may notice a mild tremor, which can be treated with low doses of other medications prescribed by your doctor.

Overdose

• Severe nausea, slurred speech or excessive trembling or wobbling are not normal side effects of lithium and could indicate an overdose. Consult a physician if these symptoms appear.

Kidney Damage

• Over time, and especially with high dosages, lithium can reduce kidney functioning. You should not take lithium if you have kidney problems, and a doctor should monitor kidney functioning while you're on lithium.
