Effectiveness

How Loratadine Affects PatientsDesloratadine is a type of medicine that helps reduce allergy symptoms. It works by blocking one type of receptor (the H1 receptor) that histamine, a chemical released during an allergic reaction, attaches to. This prevents histamine from activating cells and producing the symptoms associated with allergies. Unlike other antihistamines, desloratadine does not enter the brain and does not cause drowsiness.
How Loratadine works in the bodyDesloratadine helps to reduce allergy symptoms by blocking the effects of histamine. It does this by competing with histamine for binding to receptors in the body, keeping histamine from activating these receptors and causing symptoms. This provides temporary relief from symptoms like nasal congestion and watery eyes.

Loratadine for Itching
Silarx Loratadine Oral Solution unfortunately does not work as well as Claritin for my daughter's allergies. We'll be switching back to the latter medication.

Loratadine for Sneezing
After taking loratadine for two weeks, I started shedding hair at an alarming rate. The FDA doesn't require manufacturers to list this side effect on the packaging. Do your research before taking this drug.

Loratadine for Inflammation of the Nose due to an Allergy
The recommended dosage of this medication is 10 mg once a day. However, I find that without taking at least 20 mg, I spend the whole struggling not to sneeze and my eyes are always red and itchy. Is it safe to take more than the recommended dose?

Loratadine for Allergic Conjunctivitis
I was told to take this medicine instead of Benadryl because I also take other medications. Unfortunately, this medication caused me a lot of problems: EXTREME itchiness and welts as well as a burning sensation all over my body. I only took it for 2 days before discontinuing use; thankfully, today I am fine.

Loratadine for Allergic Conjunctivitis
My son was taking this medication for years before we realized it was the loratadine that was making him sick. He would constantly have stomach aches, anxiety, and vomiting episodes. While it did help his allergies somewhat, it definitely wasn't worth the amount of suffering he endured.

No real problems here, though it did take a little bit of time for the sneezing and runny nose to go away. In the end, my nose was left less irritated.
