There is no information in the provided sources that suggests any restrictions on dairy consumption while taking Cosentyx (secukinumab). Cosentyx is a biologic drug used to treat certain autoimmune diseases such as psoriasis and psoriatic arthritis. The drug works by targeting and blocking a specific protein in the body that causes inflammation [2]. The official website of Cosentyx [2] and Drug Patent Watch [1] do not mention any restrictions on dairy consumption while taking Cosentyx. Similarly, the Reuters article [3] about Novartis, the company that produces Cosentyx, does not mention any restrictions on dairy consumption related to the drug. However, it is always advisable to consult a healthcare professional regarding any dietary restrictions or concerns while taking any medication.
