If oxycodone 80 mg is medically appropriate, start by seeing a licensed healthcare provider who can assess your pain and write a valid prescription if needed. Only use accredited online pharmacies that require a prescription, display regulator or verification seals (for example, NABP in the U.S. or your country’s equivalent), offer pharmacist contact, and use secure payment and shipping. Be aware that 80 mg is a high dose with serious risks — discuss dosing, side effects, dependence, and safer alternatives with your clinician. Never use unverified sellers; report suspicious pharmacies to regulators and seek help for misuse concerns.
