Может запятая лишняя?

I believe counseling here has the meaning - назначение and administration - прием. For further detailed information you can check also pharmabiz.com where you can find the following information:

Patient counseling refers to the process of providing information, advice and assistance to help patients use their medications appropriately. It also includes information about the patient's illness and lifestyle modification. A patient is advised on whether drugs are to be taken before or after food, taken at bed time or in morning, with water or with juice/milk, swallow whole or chew the tablet, gap between each doses and monitor for any medication errors. All of these result in the rational use and best therapeutic action of the drugs. Lack of this information causes patient non-compliance towards medication.
