The regulatory position in Oman
Medicines in the Sultanate of Oman are regulated by the Ministry of Health, through the Directorate General of Pharmaceutical Affairs and Drug Control. Registration, importation, storage and distribution of pharmaceutical products all fall within that directorate's remit, and every product described on this page is a prescription-only medicine.
We have not verified Oman's personal-import procedure from a primary source, so we do not describe one. There is no step-by-step process set out on this page and nothing here should be read as an account of what the Ministry requires. Requirements must be confirmed directly with the Ministry of Health before any step is taken.
What we can describe is the general concept that applies across the region: a named-patient supply. A named-patient supply is a quantity of a prescription medicine intended for one identified patient, requested by that patient's treating physician, documented by a prescription and a medical report, and handled through licensed channels with the cold chain and batch traceability intact. It is not a commercial sale to the public and it is not a substitute for a locally registered product where one is available.
Assembling the documentation below before approaching the Ministry usually shortens the exchange, whichever route the Directorate General confirms applies to a given product.
We have not verified Oman's personal-import procedure. We do not describe one here. Confirm the current requirements with the Ministry of Health, Directorate General of Pharmaceutical Affairs and Drug Control.
