Alaspan Oral Solution is used to relieve the symptoms of allergies such as hay fever, conjunctivitis (red, itchy eyes), eczema, hives (urticaria), reactions to insect bites and stings, and some food allergies. It contains Loratadine, which reduces the effects of histamine, a natural chemical that triggers allergy symptoms. It may cause side effects such as drowsiness or sleepiness, headaches, fatigue, and nervousness. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
