Unindicated antihistamine prescriptions for non-allergic symptoms are low-value. Why: Antihistamines should only be used for allergic conditions; their use for viral or non-specific symptoms lacks evidence and may cause adverse effects.
Antihistamine and montelukast co-prescription for viral URTI is low-value and not clinically indicated. Why: Viral URTIs are self-limiting; antihistamines and leukotriene antagonists provide no benefit and may cause unnecessary sedation or cost.
Prescribing an antihistamine without a documented indication of an allergic or histamine-mediated condition is proposed as low-value care. Why: Antihistamines provide no benefit for non-allergic conditions like a common cold and can cause unnecessary side effects.
