Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in.
|Deductible stage||Typical copay stage|
|Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.
In the deductible stage, you’re responsible for the full cost of your prescription drugs.
Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $480 in 2022.
|After you meet your Part D deductible, you enter the initial coverage period.
During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.

Thoughts of suicide can be increased while taking Lamotrigine. If you start taking this medication and have any signs of decreased mood, panic attacks or other negative changes in mood, call your doctor right away.
Lamotrigine can cause hormone-based birth control (pills, patch, ring, etc.) to work less effectively. Be sure to use a second form of birth control while taking Lamotrigine to avoid pregnancy.
