# Lithium Carbonate 400 mg ## SHORT DESCRIPTION Lithium Carbonate 400 mg is a **mood stabilizer** primarily used in the treatment and prevention of **manic episodes associated with bipolar disorder**. It may also be used for long-term maintenance treatment to help reduce the frequency and severity of manic and depressive episodes. Lithium has a **narrow therapeutic range**, meaning the amount needed for treatment is relatively close to the amount that can cause toxicity. Regular blood-level monitoring and medical supervision are therefore essential. ## KEY BENEFITS * Helps control **acute manic episodes** * Helps stabilize mood in **bipolar disorder** * Helps reduce recurrence of manic episodes * Helps reduce the frequency of mood episodes during maintenance treatment * May help reduce the risk of relapse when taken regularly as prescribed * Supports long-term mood stabilization under medical supervision ## USES / INDICATIONS Lithium Carbonate 400 mg may be prescribed for: * **Bipolar disorder** * Acute **mania or hypomania** * Long-term maintenance treatment of bipolar disorder * Prevention of recurrent manic and depressive episodes in appropriate patients * Other psychiatric conditions only when specifically prescribed by a specialist Lithium is not an immediate-relief medicine and requires regular monitoring to ensure safe and effective treatment. ## HOW IT WORKS The exact mechanism of lithium is not completely understood. Lithium affects several signaling pathways in nerve cells and influences neurotransmitter activity and intracellular signaling. These effects help regulate abnormal mood activity and contribute to its **mood-stabilizing properties**. Lithium's effects develop gradually, making regular daily treatment and consistent blood-level monitoring important. ## DOSAGE & ADMINISTRATION * Take Lithium Carbonate 400 mg **exactly as prescribed**. * The appropriate dose varies considerably between individuals. * The 400 mg strength does not necessarily represent the complete daily dose; your doctor may prescribe different doses or dosing schedules depending on your condition and blood lithium concentration. * Lithium should be taken consistently with respect to meals. * Swallow tablets/capsules whole if they are modified-release preparations; do not crush or chew them unless the product specifically permits it. * Maintain adequate and consistent fluid and salt intake unless your doctor gives different instructions. * Do not change your dose based on how you feel. * **Regular blood tests are essential** to monitor lithium levels, kidney function and, when appropriate, thyroid function. * Blood lithium levels are usually checked after starting treatment or changing the dose and periodically during maintenance treatment. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not double the dose.** If you frequently miss doses, contact your healthcare professional for advice. ## SIDE EFFECTS Common side effects may include: * Fine hand tremor * Nausea * Diarrhea * Stomach discomfort * Increased thirst * Increased urination * Mild weakness or fatigue * Weight gain * Drowsiness * Dry mouth Some side effects may improve as the body adjusts to treatment. ### Signs of Lithium Toxicity Lithium toxicity can be serious and requires urgent medical attention. Symptoms may include: * Increasing or coarse tremor * Severe nausea or persistent vomiting * Severe or persistent diarrhea * Muscle weakness * Unsteadiness or difficulty walking * Slurred speech * Confusion * Extreme drowsiness * Poor coordination * Blurred vision * Severe dizziness * Seizures * Loss of consciousness If lithium toxicity is suspected, **do not take another dose until you have received urgent medical advice**. ## PRECAUTIONS & WARNINGS * Lithium has a **narrow therapeutic index** and must be carefully monitored. * Maintain adequate hydration, particularly during hot weather, exercise or illness. * Avoid sudden major changes in dietary salt intake unless instructed by your doctor. * Dehydration caused by vomiting, diarrhea, fever or excessive sweating can increase lithium levels and toxicity risk. * Contact your doctor promptly if you develop significant vomiting, diarrhea, fever or dehydration. * Tell your doctor if you have **kidney disease, heart disease or thyroid disease**. * Lithium can affect **kidney and thyroid function**, so periodic monitoring is important. * Inform your doctor if you are pregnant, planning pregnancy or breastfeeding. * Do not stop lithium suddenly without medical advice. * Avoid making significant changes to your fluid or salt intake without discussing them with your healthcare professional. * Alcohol may worsen dizziness, drowsiness and impaired coordination. * Tell every healthcare professional treating you that you take lithium. * Older adults may be more sensitive to lithium toxicity. * Avoid self-medication with NSAID painkillers or diuretics because they can significantly affect lithium levels. ## DRUG INTERACTIONS Many medicines can increase or decrease lithium levels. Important interactions include: * **NSAIDs** such as ibuprofen, naproxen and diclofenac — may increase lithium levels and toxicity risk. * **ACE inhibitors** such as lisinopril and enalapril — may increase lithium concentrations. * **ARBs** such as losartan and olmesartan — may increase lithium levels. * **Diuretics**, particularly thiazide diuretics — can significantly increase lithium concentrations. * Some other diuretics can also alter lithium levels. * **Metronidazole** — may increase lithium concentrations. * **Tetracycline antibiotics** — may increase lithium levels. * **Caffeine** — changes in caffeine intake can affect lithium levels in some patients. * Other medicines affecting kidney function or fluid/electrolyte balance may alter lithium concentrations. Do not start, stop or change any medicine without informing your doctor or pharmacist. ## STORAGE INFORMATION * Store Lithium Carbonate according to the manufacturer's instructions. * Keep the medicine in its original packaging. * Store at the recommended room temperature. * Protect from excessive heat, moisture and direct sunlight. * Keep the container tightly closed. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets or capsules if the packaging is damaged. ## PRESCRIPTION STATUS **Prescription medicine.** Lithium Carbonate 400 mg should only be used under the supervision of a qualified healthcare professional because regular blood-level and clinical monitoring is required. ## GENUINE MEDICINE ASSURANCE For safe and genuine Lithium Carbonate 400 mg: * Purchase from a licensed and reputable pharmacy. * Check the medicine name and strength. * Verify the manufacturer's details. * Check the batch number and expiry date. * Ensure the packaging and seal are intact. * Avoid products with damaged or suspicious packaging. * Do not use expired medicine. * Follow the manufacturer's storage instructions. * Consult a pharmacist if you have concerns about product authenticity. ## FAQ ### What is Lithium Carbonate 400 mg used for?
