A legitimate online pharmacy will require a prescription from a licensed healthcare provider before selling tramadol. This ensures that the medication is appropriate for your condition and minimizes the risk of misuse. Verify Pharmacy Credentials: Ensure that the online pharmacy is licensed and accredited. In the United States, look for accreditation by the National Association of Boards of Pharmacy (NABP) or check if it's included in the FDA's list of verified online pharmacies.
