LITHOSUN 300MG

# Lithium Carbonate 300 mg ## SHORT DESCRIPTION Lithium Carbonate 300 mg is a **mood-stabilizing medicine** primarily used in the treatment and prevention of episodes of **bipolar disorder**. It can help reduce manic episodes and may help prevent future episodes of mania and depression. Lithium has a **narrow therapeutic range**, meaning the amount needed for benefit is relatively close to the amount that can cause toxicity. Regular blood-level monitoring and medical supervision are therefore important during treatment. ## KEY BENEFITS * Helps control **manic episodes** associated with bipolar disorder * Helps prevent recurrence of manic episodes * Helps provide long-term mood stabilization * May reduce the frequency and severity of bipolar mood episodes * May be used as part of a long-term bipolar disorder treatment plan * Can help maintain mood stability when taken consistently as prescribed ## USES / INDICATIONS Lithium carbonate may be prescribed for: * **Bipolar disorder** * Treatment of acute mania or hypomania * Long-term prevention of manic episodes * Maintenance treatment to reduce recurrence of bipolar mood episodes * Certain other psychiatric conditions in selected patients under specialist supervision The exact approved uses may vary according to the country and specific product. ## HOW IT WORKS Lithium is a **mood stabilizer**. Its exact mechanism is complex and is not completely understood. It affects several signaling pathways in the brain, including intracellular signaling systems and neurotransmitter-related processes. These effects help stabilize abnormal changes in mood and reduce the tendency toward manic episodes. Lithium does not work like a conventional sedative and should be taken consistently for sustained mood stabilization. ## DOSAGE & ADMINISTRATION * Take Lithium Carbonate 300 mg exactly as prescribed. * The dose is individualized according to the condition, response to treatment, kidney function, age and **serum lithium concentration**. * Lithium is commonly taken in divided doses or according to the specific formulation prescribed. * Take it at approximately the same times each day. * Maintain a **consistent intake of fluids and dietary salt** unless your doctor advises otherwise. * Do not suddenly make major changes to your fluid or salt intake. * Swallow extended-release tablets whole if your product is an extended-release formulation. * Do not crush or chew modified-release tablets unless specifically permitted by the product instructions. * Do not stop lithium suddenly without medical advice. ### Blood Monitoring Regular blood tests are an important part of lithium treatment. Your doctor may monitor: * Serum lithium concentration * Kidney function * Thyroid function * Electrolytes * Calcium levels * Other parameters depending on your medical condition Lithium blood samples are usually taken at a standardized time in relation to the previous dose so that the result can be interpreted accurately. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not take two doses together.** Follow your doctor's specific instructions. ## SIDE EFFECTS Common side effects may include: * Fine hand tremor * Increased thirst * Increased urination * Nausea * Diarrhea * Stomach discomfort * Mild weakness * Fatigue * Weight gain * Acne or skin changes Some side effects may improve as the body adjusts to treatment. ### Signs of Lithium Toxicity Lithium toxicity can be serious. Seek urgent medical attention if you experience: * Severe or worsening tremor * Persistent vomiting or diarrhea * Severe drowsiness * Muscle weakness * Loss of coordination * Unsteady walking * Slurred speech * Confusion * Blurred vision * Severe dizziness * Seizures * Loss of consciousness **Do not wait for symptoms to become severe if lithium toxicity is suspected.** ## PRECAUTIONS & WARNINGS * Lithium has a **narrow therapeutic index** and requires careful monitoring. * Dehydration can increase lithium levels and the risk of toxicity. * Excessive sweating, vomiting, diarrhea or fever can affect lithium levels. * Maintain adequate and consistent fluid intake. * Avoid sudden changes in dietary salt intake. * Tell your doctor if you have **kidney disease**. * Tell your doctor if you have thyroid disease. * Lithium may cause or worsen hypothyroidism in some patients. * Inform your doctor if you have heart disease. * Tell your doctor if you have psoriasis, as lithium may worsen it. * Older adults may be more sensitive to lithium. * Avoid self-medication with medicines that can increase lithium levels. * Do not stop lithium abruptly without medical supervision. * Pregnancy requires careful specialist assessment because lithium can affect fetal development. * If breastfeeding, discuss lithium use with your healthcare professional. * Avoid driving or operating machinery if you experience dizziness, drowsiness, impaired coordination or blurred vision. ## DRUG INTERACTIONS Lithium interacts with several commonly used medicines. ### Important Interactions * **NSAIDs** such as ibuprofen, naproxen and diclofenac — may increase lithium levels and toxicity risk. * **ACE inhibitors and ARBs** such as enalapril, lisinopril and losartan — may increase lithium concentrations. * **Diuretics**, particularly thiazide diuretics — can significantly increase lithium levels. * **Loop diuretics** may also affect lithium concentrations. * **Metronidazole** — may increase lithium levels in some patients. * **Tetracycline antibiotics** — may increase lithium concentrations. * **SGLT2 inhibitors and other medicines affecting fluid balance** may potentially alter lithium levels and require monitoring. * Other medicines that affect kidney function or sodium/fluid balance may alter lithium concentrations.
