Lithium (lithium carbonate) is a drug used to treat bipolar disorder and schizophrenia. This medication is available in both tablet and liquid form. It may take up to three weeks before you see any improvement in your symptoms, reports PDR Health. Toxic levels of this drug may occur. If you are taking lithium, be sure to have your blood levels checked frequently.
Fine Hand Tremor
You may experience fine hand tremors while taking lithium. You may notice mild trembling of one or both of your hands. If you find that this symptom continues to worsen and negatively impacts your daily activities, contact your health care provider.
Nausea and Diarrhea
Nausea and diarrhea are common side effects of lithium. These side effects may diminish over time as your body has a chance to get used to this medication. If nausea and diarrhea become severe, you may become dehydrated. Drink at least six glasses of water each day. Eating a bland diet and having several small meals throughout the day may help to alleviate nausea.
Polyuria and Polydipsia
Increased production of urine (polyuria) and excessive thirst (polydipsia) are two common side effects that are usually not serious problems, states the National Alliance on Mental Illness (NAMI). These side effects may diminish as your body adjusts to lithium.
Weight Gain
Weight gain is a common side effect while taking lithium. Eating a sensible diet and exercising daily may help to avoid additional weight gain.
Hypothyroidism
You may experience hypothyroidism while taking lithium. This causes low levels of thyroid hormone in your body. Signs and symptoms of hypothyroidism include weight gain, dry skin, hair loss, sensitivity to cold, mental depression and hoarseness. A simple blood test will determine if you have hypothyroidism. This condition is treated with medication.
Lithium Toxicity
Consumers should tell their doctor immediately if they develop lack of coordination, muscle weakness, slurred speech, nausea, vomiting, diarrhea, confusion or an increase in tremors or shaking, states NAMI. These are symptoms of having too much lithium in your body.
