Cetirizine Fattening? What It Serves For, Dosage And Side Effects

Cetirizine Fattening? What It Serves For, Dosage And Side Effects.Cetirizine in tablet form, also called Cetirizine Dihydrochloride, is an oral, adult and pediatric medicine from 12 years of age.The medicine is found in packs containing 12 tablets of 10 mg, according to information from its package leaflet provided by the National Health Surveillance Agency (Anvisa).

What is Cetirizine for?

Also according to information from its label, Cetirizine Dihydrochloride is indicated to alleviate the nasal and ocular symptoms of seasonal (temporary) and perennial (lasting) allergic rhinitis and to relieve the symptoms of urticaria – allergic reaction characterized by red lesions and swollen skin that appear on the skin, according to the Brazilian Society of Dermatology (SBD).Its marketing is allowed only medically presentation of the prescription.

Does cetirizine put on weight?

For those concerned about losing weight or keeping fit without gaining extra pounds and having been prescribed the drug, it is important to know that Cetirizine is fattening in some cases, although it is quite rare.

Cetirizine dihydrochloride leaflet itself presents weight gain as one of the possible adverse drug reactions. However, as this side effect appears in the rare reaction category (≥1 / 10,000 and <1 / 1,000 users), we cannot beat the hammer and determine that Cetirizine is fattening in many cases. This seems to be an unlikely side effect for the vast majority of people, but possible.

Another adverse reaction associated with weight gain that is presented by the package leaflet is increased appetite. However, the frequency with which this effect can be observed is not known.

That is, when taking the medicine, there are some chances that the patient will experience weight gain, but it is not possible to determine that Ceritizine puts on weight for all users.

To protect yourself from this, you can try to take better care of your diet by eating healthy, controlled, balanced and nutritious food without overeating, and exercise regularly to help increase calorie expenditure.And if you are experiencing weight gain while using Cetirizine, talk to your treating physician to find out if the problem was actually caused by the medicine and check with him how to get around it.
