Loratadine 10 mg is used to relieve symptoms of seasonal allergic rhinitis and chronic idiopathic urticaria [1]. It is an antihistamine that works by blocking the effects of histamine, a substance the body produces during an allergic reaction [2]. Histamine is responsible for symptoms such as itching, sneezing, runny nose, itchy or watery eyes, and hives [2].
What symptoms does loratadine 10 mg treat?
Loratadine 10 mg is effective in alleviating a range of allergy symptoms. These include sneezing, runny nose, and itchy nose or throat, which are common with seasonal allergies like hay fever [1]. For hives, loratadine 10 mg helps to reduce itching and the size and number of hives [1].
How does loratadine work?
Loratadine is a second-generation antihistamine. It selectively antagonizes peripheral H1-receptor sites [3]. Unlike some older antihistamines, it has a low tendency to cross the blood-brain barrier, which means it is less likely to cause drowsiness [3]. It provides temporary relief from allergy symptoms by preventing histamine from binding to histamine receptors [2].
When should I take loratadine 10 mg?
Loratadine 10 mg is typically taken once a day [1]. It can be taken with or without food [1]. For the best results, it should be taken at around the same time each day [1].
What is the difference between loratadine and other allergy medications?
Loratadine is a non-drowsy antihistamine, distinguishing it from first-generation antihistamines like diphenhydramine, which can cause significant sleepiness [3]. Compared to other second-generation antihistamines like cetirizine, loratadine may have a lower incidence of sedation, although individual responses can vary [4]. It is also available over-the-counter, making it easily accessible [1].
How long does loratadine take to start working?
