Can a person with an allergy to cow's milk protein use drugs containing lactose in the composition?

A person with an allergy to cow's milk protein can take medications in which the excipient is lactose. In case of allergy to cow's milk proteins, it is necessary to eliminate milk and dairy products from the diet. Lactose intolerance is the result of insufficient production of an enzyme that is responsible for the digestion of lactose in the digestive tract. Thus, cow's milk allergy is not synonymous with lactose allergy or lactose intolerance.
