Saving Money on Bipolar Medications
Adherence and Cost
Medication adherence is one of the biggest challenges in bipolar disorder. Non-adherence leads to relapse, hospitalization, and ultimately higher costs. If cost is causing you to skip doses or ration medication, tell your doctor immediately — there is almost always a cheaper alternative.
The Bottom Line
Bipolar disorder is highly treatable, and generic medications make treatment affordable for most Canadians. Lithium remains one of the most effective and cheapest options at under $20/month.
