Yes - if the premiums were not paid with pre-tax money.
Generally if you have insurance through your company, your portion of the premium is paid for with pre-tax payroll deductions, and Box 1 of your W2 will be adjusted accordingly. Double-check if your total income reported has been adjusted. Further reading.
For the self-employed, this can be a great deduction. Further reading.
The IRS online worksheet "Can I Deduct My Medical and Dental Expenses?" is a great tool to work through whether you can take this (or other) medical deductions. The summary on the description page says it takes into account (among other things):
"If you were reimbursed or if expenses were paid out of a Health Savings Account or an Archer Medical Savings Account"
...implying that the no double-dip rule holds true.
You can include in medical expenses insurance premiums you pay for policies that cover medical care. You can't include in medical expenses insurance premiums that were paid and for which you are claiming a credit or deduction. Medical care policies can provide payment for treatment that includes:
- Hospitalization, surgical services, X-rays,
- Prescription drugs and insulin,
- Dental care,
- Replacement of lost or damaged contact lenses, and
- Long-term care (subject to additional limitations). See Qualified Long-Term Care Insurance Contracts under Long-Term Care, later.
If you have a policy that provides payments for other than medical care, you can include the premiums for the medical care part of the policy if the charge for the medical part is reasonable. The cost of the medical part must be separately stated in the insurance contract or given to you in a separate statement.
If you itemize your deductions for a taxable year on Form 1040, Schedule A (PDF), Itemized Deductions, you may be able to deduct expenses you paid that year for medical and dental care for yourself, your spouse, and your dependents. You may deduct only the amount of your total medical expenses that exceed 10% of your adjusted gross income or 7.5% if you or your spouse is 65 or older. The 7.5% limitation is effective only from January 1, 2013 to December 31, 2016 for individuals age 65 and older and their spouses. You figure the amount you are allowed to deduct on Form 1040, Schedule A.
Deductible medical expenses may include but are not limited to the following:

- Payments for insurance premiums you paid for policies that cover medical care or for a qualified long-term care insurance policy covering qualified long-term care services. However, if you are an employee, do not include in medical expenses the portion of your premiums treated as paid by your employer under its sponsored group accident, health policy, or qualified long-term care insurance policy. Also, do not include the premiums that you paid under your employer-sponsored policy under a premium conversion policy (pre-tax), paid by an employer-sponsored health insurance plan (cafeteria plan) or any other medical and dental expenses unless the premiums are included in box 1 of your Form W-2 (PDF), Wage and Tax Statement. For example, if you are a federal employee participating in the premium conversion program of the Federal Employee Health Benefits (FEHB) program, you may not include the premiums paid for the policy as a medical expense since they are never included in your gross income.
