Patches should be applied to clean, dry skin. Avoid placing patches on your face, head, or any areas with broken or irritated skin. Some of the best spots include wrists, upper arms, shoulder blades, collarbone, back, hips, thighs, and ankles. Our melatonin patches should be applied only when you want to sleep. Otherwise you can apply our patches at any time, day or night! For sensitive skin, rotate patch sites (arm, back, hip, shoulder, etc.) — don’t use the same spot every day.

Yes, our patches expire after 3 years. Each package of patches includes a printed expiration date on the back of the pack for you to reference.

Ingredients will release from the patch over the course of 8-12 hours, but if you forget to remove it, don't stress. Nothing will happen if you remove it after the 12 hour mark.

If you don’t have your HSA or FSA card handy, still select “Flex | Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.

We strongly recommend checking with your HSA/FSA provider to see if a purchase is eligible prior to completing the purchase. However, if you believe your claim has been wrongly denied, please send over any response from your HSA/FSA provider to us so we can share it with Flex and receive guidance on the next best steps to take. Please note that employer-sponsored FSAs can determine what products are eligible beyond the IRS’s guidelines, so it’s extremely important to check prior to purchase.

The ability to apply for FSA reimbursement in a future calendar year depends on the policy of the specific FSA provider. Most FSA administrators require that the purchase be made during the time of coverage. For example, if the FSA coverage is for 2025, all purchases typically need to be made and/or submitted for reimbursement within that coverage period.

Please email support@withflex.com and they will reach out to their telehealth team to reprocess and send your corrected Letter of Medical Necessity.
