Product Description
Cetirizine dihydrochloride is a type of antihistamine medication used to treat allergy symptoms such as sneezing, runny nose, itching, and watery eyes. It works by blocking the effects of histamine, which is a chemical produced by the body in response to allergens such as pollen, dust mites, and animal dander.
Cetirizine dihydrochloride is available over-the-counter (OTC) in many countries and is often sold under the brand names Zyrtec, Reactine, or Cetrizine. It is also available in prescription strength for more severe allergy symptoms or for people who do not respond to the OTC strength.
The medication is usually taken orally, either as a tablet, capsule, or liquid. Common side effects include drowsiness, dry mouth, headache, and nausea. In rare cases, it can cause more serious side effects such as difficulty breathing or an allergic reaction. It is important to talk to a healthcare provider before taking cetirizine dihydrochloride, especially if you are pregnant or have any other health conditions.
