If you are filing married filing separately you both have to itemize or both have to use standard deduction. So unless you are in a community property state, divvy up the itemized deductions to suit yourselves. Either split the medical insurance premiums or have only one of you use them. It likely will not have any effect. You have to meet a high threshold to get any benefit from entering medical expenses. Only the amount that is OVER 7.5% of your AGI even counts.
Are you aware that filing separate returns means you lose certain credits like education credits, earned income credit and the childcare credit? Married filing separately is usually the worst way to file.
And if one of you itemizes the other spouse has to itemize too even if you do not have enough deductions to exceed your standard deduction.
