What is the difference between loratadine and desloratadine?

Both belong to the group of antihistamines, that is, they act precisely on histamine, which is the substance that our body releases during allergic conditions. For this reason, these drugs are responsible for blocking H1 receptors directly related to allergic dermatitis, rhinitis and urticaria.

In this sense, one of its main differences is that loratadine has drowsiness as a side effect while desloratadine does not. Another difference is that loratadine is a second generation antiallergic that is generally sold without a prescription and the other antihistamine is third generation derived from the previous one and is required from the medical formula.

In the case of desloratadine it can be administered in patients with asthma, in the case of perennial allergic rhinitis and in fact it can be used in combination with other medications, loratadine is not recommended in these cases.

Who can take desloratadine?

Its use is recommended for both adults and children from 6 months of age, as long as the doctor indicates it. This antiallergic can be administered in patients who experience various types of allergies, such as allergic rhinitis, water and chronic urticaria or any other allergic condition or skin reactions.

Does Desloratadine make you sleepy?

Because it is part of the group of second-generation antihistamines, it is mainly characterized by not causing drowsiness. This is because it does not cross the blood-brain barrier and therefore does not cause impairment in cognitive motor performance.

When taking medications this is one of the questions that arise in patients because there are some antiallergic drugs that tend to gain weight. In this case, there is no such concern because this particular antihistamine belongs to the third generation of the same and its effect on the central nervous system is more specific and less invasive, and therefore does not cause that feeling of hunger and tendency to rise of weight that if they cause the first generation.

Can you drive while taking desloratadine?

This is another doubt that assails patients when they are prescribed an antihistamine because it is commonly known that one of its effects is drowsiness. But this medicine does not produce it, so you can carry out normal activities, even driving, without worry. Only in the extreme case that it causes drowsiness when ingested, should you inform your doctor immediately.
