Are GLP-1s tax deductible? How to take Ozempic, Wegovy, and other weight loss drugs.

About 12% of adults in the US take a GLP-1 drug such as Ozempic, Mounjaro, Zepbound, or Wegovy, according to the 2025 KFF health tracking survey. But these blockbuster drugs can cost more than $1,000 a month for patients who pay out of pocket. Even with insurance, monthly expenses can exceed several hundred dollars.

You can deduct GLP-1s as medical expenses on your taxes, depending on why the medication was prescribed. But doing so may not reduce your taxes. Here is the reason.

Unpaid medical expenses incurred by you, your spouse, and dependents are generally tax deductible, but a few caveats apply. Here are the rules.

You can’t take the standard deduction

You can only deduct medical expenses as opposed to claiming the standard deduction. Itemizing will only save you money if your deductions exceed the standard deduction for your tax filing status. The standard deduction is $15,750 for single filers and $31,500 for married joint filers in 2025 (applies to returns due April 15, 2026). These amounts increase to $16,100 for single filers and $32,200 for married joint filers in 2026 (effective for returns due by April 15, 2027).

The medical expense deduction only applies to reimbursed expenses that exceed 7.5% of your adjusted gross income, or AGI. In other words, if your income is $100,000 and you had $12,000 in medical bills for the year (excluding health insurance premiums), you can only deduct $4,500 in medical expenses.

Health care expenses are tax deductible only if they are what the Internal Revenue Service (IRS) calls qualified medical expenses. That means a licensed physician prescribes the “diagnosis, treatment, mitigation, treatment, or prevention” of disease. As we will discuss in the next section, GLP-1 drugs can sometimes fall into the gray area ahead.

The IRS will generally consider GLP-1 medications to be qualified tax-deductible medical expenses if both of the following qualifications are true:

• A doctor or other medical provider diagnoses you with a disease, AND

• GLP-1 drugs such as Wegovy or Ozempic are prescribed to treat the disease.

If your doctor prescribed GLP-1 because you’ve been diagnosed with type 2 diabetes, that’s a clear example of when you can deduct your unreimbursed expenses — as long as you do things and deduct more than 7.5% of your AGI.

Likewise, if your doctor has diagnosed you as obese and prescribed GLP-1 for weight loss, you may be able to reduce costs because the IRS recognizes obesity as a chronic medical condition. You can also deduct the cost if your doctor diagnoses you with another disease and prescribes GLP-1 as part of a weight loss program that is intended to treat it. For example, if a doctor diagnosed you with hypertension and prescribed GLP-1 to help you lose weight and lower your blood pressure.

Medicines prescribed for weight loss are not tax deductible. If your doctor has prescribed medication because they recommend shedding pounds to improve your overall health, the cost is not tax deductible.

Weight loss drugs prescribed through phone companies and filled through compounding pharmacies can fall into this gray area. Many prescribe GLP-1 through an online consultation where a licensed clinician reviews your self-reported height, weight, medical history, and health goals. A doctor determines whether a drug is medically appropriate, but usually does not make a diagnosis. Your expenses will generally not be tax deductible in this situation because you did not incur them for the treatment of the disease.

You can only deduct non-reimbursable medical expenses. That means that if your health insurance or patient assistance plan pays for part of your GLP-1 costs, you can deduct that part from your pocket.

Let’s say you use a drug that costs $1,000 a month, but your health insurance covers most of the cost, so you’re responsible for a $150 monthly co-payment. If you write, you can deduct your $150 payment if your medical expenses reach 7.5% of your annual AGI ($1,800 total if you paid that amount each month for a year). But you can’t deduct the full $1,000 monthly cost of the drug.

You can pay for weight loss medication through your health savings account (HSA) or health care variable income account (FSA) — but only if it’s used to treat a specific condition. If you take a drug solely for weight loss without a medical diagnosis, you will not be able to pay through your HSA or FSA or claim reimbursement from your account.

You can’t deduct any expenses you pay with an HSA or FSA. Because you’re not taxed on the money you contribute to any type of account, you don’t get any additional tax deductions when you use those funds for health expenses.

You may need to get a letter of medical necessity from your provider to get GLP-1s reimbursed to your account. The letter should include your diagnosis, prescribed treatment, and how it will improve your prognosis. The document can also be useful in the event of an audit.

Itemizing only makes sense if your tax write-off is more than the standard deduction – and about 90% of taxpayers take the standard deduction instead of itemizing. As you prepare your return, you’ll need to have at least $15,750 in deductions if you’re single or $31,500 if you’re a married filer to save money by doing things.

If you qualify for other additional deductions, such as the estate tax write-off and state and local taxes, it’s possible that GLP-1s and other medical expenses may tip the scale in favor of itemizing. But remember that the first 7.5% of your AGI that goes toward medical expenses is not tax deductible. Even in years when you have significant health care expenses, taking the standard deduction often yields significant tax savings.

For many taxpayers whose insurance meets the criteria for a high-deductible health plan, subsidizing an HSA and using it to pay for GLP-1 medications and other medical expenses often saves more money on taxes. You contribute pretax funds, and withdrawals are also tax-free.

In 2026, you can contribute up to $4,400 for single coverage or $8,750 for family coverage. So if you have one plan, you can withdraw the annual account and reduce your taxable income by $4,400. You can withdraw those funds tax-free to pay for GLP-1 and other health expenses — or you can let the funds roll over from year to year, as the money stays with you or you change plans.

GLP-1s are medical expenses that you can deduct from your taxes if they are prescribed to treat a diagnosed medical condition, such as diabetes, obesity, or heart disease. If you are given a drug because you want to lose weight, but it is not used to treat a specific disease, you cannot deduct the cost for tax purposes.

You can stop Ozempic for weight loss if your provider has prescribed it to treat a certain medical condition, such as obesity, diabetes, fatty liver disease, or high blood pressure. However, if the drug is prescribed to help you lose weight for cosmetic reasons or to improve your overall health, it is not tax deductible.

Gym membership fees are not tax deductible, but you may be able to deduct the cost of participating in a weight loss program at the gym if it is intended to treat a medical condition.
