Depends: if taken on empty stomach, 30 minutes should be enough to feel its effect, if on a full stomach takes longer, check that you have taken the right dose, also depends on the expected effect, to induce sleep, might not work similarly in every individual, if for itching/ allergy problems might need something else to get symptom control, at any rate don't exceed recommended dosage from all sources
