Other side effects include tremors, blurry vision, weight gain, fatigue, weakness, hair loss and dizziness. Women who are pregnant or trying to become pregnant shouldn't take Divalproex.

How Much Does Divalproex Cost With Medicare?

The cost of Divalproex with Medicare depends on whether you've met your plan's annual deductible. A deductible is the amount of money you must pay every year before your insurance plan kicks in. If you haven’t paid your full deductible for the year, you need to pay the full cost of the drug. However, if you've already met your required deductible, you're only responsible for paying your co-pay.

Your co-pay can be a set amount per prescription or a percentage of the total cost. Check your plan details to determine your specific co-pay amount.

What Tier Is Divalproex?

Most Medicare drug prescription plans include Divalproex in Tier 2 of their formulary. Typically, the higher the tier level, the more expensive the medication is. This factor makes Divalproex a moderately priced prescription medication.

Does Medicare Have Any Restrictions on Coverage?

In some cases, Medicare plans require prior authorization for this medication. This means your physician must contact your insurance provider to explain why this medication is medically necessary. You may also be limited when it comes to the amount of the drug you can receive at one time. For example, if you can only receive a 30-day supply of Divalproex, your doctor may need to renew your prescription each month.
