Coumadin, or warfarin, requires a prescription. You cannot buy it over-the-counter.
Obtain Coumadin only from legitimate sources:
- Your Doctor: This is the primary and safest way to acquire your prescription. Your doctor will determine the appropriate dosage and monitor your treatment. Licensed Pharmacies: Once you have a prescription, fill it at a registered pharmacy. Verify the pharmacy’s legitimacy through your state’s board of pharmacy. Mail-Order Pharmacies: Reputable mail-order pharmacies can fill prescriptions, but ensure they are licensed and accredited. Check their credentials thoroughly.
Avoid:
- Online pharmacies without a verifiable license: These often sell counterfeit or substandard medications. Unlicensed vendors: Purchasing from unregulated sources poses significant health risks. Individuals selling Coumadin: This is illegal and dangerous; the medication’s quality cannot be guaranteed.
Always check the medication’s packaging for authenticity and consult your pharmacist if you have any questions about your prescription.
Regularly schedule follow-up appointments with your doctor for blood tests to monitor your INR levels. Strictly follow your doctor’s instructions regarding dosage and medication interactions. Report any side effects immediately to your doctor or pharmacist.
