Important information about Claritin Nasal Spray

How does Claritin work?

The active ingredient in Claritin is loratadine. When we encounter allergens, our immune system releases histamines, which trigger allergy symptoms. Claritin selectively blocks H1 receptors, preventing histamines from binding to them. By inhibiting the effects of histamines, Claritin helps to alleviate common allergy symptoms.

How do you use Claritin?

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Claritin. However, the following is a synopsis of the general guidelines for the use of Claritin:

  • Take Claritin at the same time each day: Establishing a routine will help ensure consistent and continuous relief from your allergy symptoms.
  • Avoid taking Claritin with grapefruit juice: Grapefruit juice can interfere with the absorption of Claritin, potentially reducing its effectiveness. It is best to avoid consuming grapefruit juice while using Claritin.
  • Store Claritin properly: Keep Claritin in a cool, dry place away from direct sunlight. Follow the storage instructions provided on the packaging to maintain its potency.
  • Stay hydrated: Ensuring an adequate intake of water can help minimize the occurrence of dry mouth, a common side effect of Claritin.
