Customs problem with a shipment of medication

I was called from Emirates Post to pick up a delivery at the Customs. As the customs opened the package, it turned out that medication was inside.

I didn't order or initiate the delivery of any medication and hence should've been asked to discard the delivery as no sender was mentioned.

Instead, the Customs forwarded the item to the Ministry of Health for their assessment. Now, the Ministry of Health is requesting me to meet their doctor to evaluate why I need this medication.

Again, I didn't order or initiate the delivery of medication and don't need any.

Kindly advise what shall I do in this matter as I am afraid that the medication could contain banned substances.
