Prescription ocular antihistamines and over-the-counter ocular antihistamines can bring relief to patients whose lid inflammation is caused by allergies.
Upon first commencing treatment, opipramol is rather sedating in nature due to its antihistamine properties, but this effect becomes less prominent with time.
Antihistamines are widely available over the counter at drug stores (without a prescription), in the form of allergy medication and some cough medicines.
