CPM vs Cetirizine – Difference and Comparison

What is CPM?

Chlorpheniramine (CPM) is an antihistamine medication used to treat symptoms of allergies, such as hay fever, hives, and allergic rhinitis. It works by blocking the action of histamine, a chemical released by the body in response to an allergic trigger. This helps to reduce symptoms such as sneezing, itching, and runny nose. Chlorpheniramine (CPM) is available in both prescription and over-the-counter forms.

It is taken orally in the form of a tablet or liquid. The recommended dosage and frequency of use will depend on the specific condition being treated and the individual patient’s age and medical history. It is essential to follow the instructions provided by a healthcare provider or pharmacist when taking Chlorpheniramine (CPM).

Like other antihistamines, Chlorpheniramine (CPM) may cause side effects such as drowsiness, dry mouth, and dizziness. It may also interact with certain medications and should not be taken by people allergic to it or other antihistamines. Discussing all medications and allergies with a healthcare provider before taking Chlorpheniramine (CPM) is important.

What is Cetirizine? 

Cetirizine is a medication that people take for allergies, like hay fever, or for skin conditions like hives. It works by blocking histamine, a chemical that the body makes when you have an allergic reaction. This can help with symptoms like sneezing, itching, and a runny nose. You can get cetirizine as a pill or cream, and it’s taken once a day.

The dose depends on what you’re using it for and your age and weight. Make sure to follow the instructions on the label, and don’t take more than recommended. Like most meds, cetirizine can have side effects, but they’re pretty mild. They might include drowsiness, dry mouth, or dizziness. If you have any side effects or other health conditions, let your doctor know before taking cetirizine.

Some common side effects of Cetirizine may include drowsiness, dry mouth, and dizziness. It is important to let a healthcare provider know if these or any other side effects are experienced while taking Cetirizine.
