Inefficient Medication

Someone has developed hemorrhoid disease. He visited a doctor and rectal suppositories were prescribed to him. The doctor did not explain how to use them, since he thought that this was obvious.
Several days later the patient comes to the doctor and complains: "The drug does not work at all. I swallow it and swallow, but this gives no effect".
?- You swallow them??!
?- Of course. Do you think that I am a pervert and I stick them up my a**?
