Drug Description


Lithmax is prescribed for the management of manic episodes in bipolar disorder, characterized by symptoms such as hyperactivity, rapid speech, impaired judgment, decreased need for sleep, aggression, and irritability. 

Moreover, Lithmax can be prescribed as a maintenance therapy for individuals diagnosed with bipolar disorder, lessening the occurrence and intensity of manic episodes. 

As an antimanic medication, Lithmax functions to stabilize mood and mitigate behavioral extremes by restoring the balance of specific natural substances (neurotransmitters) within the brain. 

Uses and Dosage 

Before starting or refilling your prescription, carefully review the provided medication guide and patient information leaflet for Lithmax. For any inquiries or additional details, consult your doctor or pharmacist. 

Lithmax dosage varies for each patient based on individual medical conditions, lithium blood levels, and response to the treatment. In children, the dosage is also contingent upon their weight. 

Typically, this medication is taken 2 to 3 times a day as prescribed by the doctor. It can be ingested alongside or immediately after meals to minimize the possibility of stomach upset. 

Avoid crushing or chewing Lithmax tablets, as this action may release the entire drug at once, heightening the risk of side effects. Only split tablets if they have a score line, and upon the recommendation of your doctor or pharmacists, swallow them whole or split without crushing or chewing. 

Dosage adjustments may be made periodically by your doctor. Take this medication consistently and precisely as instructed, at similar times daily for the best outcome. Avoid taking more than prescribed, as even a slightly higher dose can lead to an overdose. 

Continue taking Lithmax even if you feel better; do not discontinue without consulting your doctor.
