What Is Cetirizine 10 mg?
CET10 is a common term for medications containing cetirizine hydrochloride 10 mg, an active ingredient widely available over-the-counter. It is the same active compound found in the brand-name medication, Zyrtec®. Cetirizine is a second-generation antihistamine, offering 24-hour allergy symptom relief with a reduced risk of drowsiness compared to older antihistamines. Its accessibility makes it a popular choice for managing allergies.
Mechanism of Action: How Cet10 Works
Allergic reactions occur when the body releases histamine in response to allergens like pollen or pet dander. Histamine causes common allergy symptoms such as sneezing, runny nose, itchy eyes, and hives. Cetirizine is a selective antagonist of the histamine H1-receptor, meaning it blocks histamine from binding to these receptors and causing allergic effects. This action effectively alleviates a broad range of allergy symptoms.
Common Uses and Indications
Cet10 is primarily used to treat symptoms of allergic conditions in adults and children over 6 years old. Its main uses include:
- Seasonal allergic rhinitis (hay fever): Relieves symptoms from outdoor allergens.
- Perennial allergic rhinitis: Manages symptoms from indoor allergens.
- Chronic idiopathic urticaria (hives): Treats itching and swelling of unexplained hives.
- Other allergic reactions: Helps with minor skin reactions.
Administration
Cetirizine 10 mg tablets can be taken with or without food and should be swallowed with water. Adhering to prescribed or package instructions is important. Consult a healthcare professional regarding administration instructions, especially for children or individuals with specific health conditions like kidney problems.
Side Effects and Precautions
While generally safe, cet10 can cause side effects, often mild and temporary.
Common Side Effects
- Drowsiness
- Fatigue
- Dry mouth
- Headache
- Dizziness
Less Common and Serious Side Effects
Though uncommon, serious side effects require immediate medical attention. These include:
- Signs of allergic reaction (swelling, difficulty breathing)
- Fast heartbeat
- Vision problems
Important Precautions
- Avoid alcohol, as it enhances drowsiness.
- Do not drive or operate machinery if experiencing sleepiness.
- Consult a doctor if pregnant, planning pregnancy, or breastfeeding.
- Be aware of a rare risk of severe itching upon discontinuing long-term use.
Comparison of Cetirizine (Cet10) and First-Generation Antihistamines
Cetirizine offers advantages over older antihistamines like diphenhydramine (Benadryl), primarily due to a better safety profile and convenience. Key differences are shown in the table below:
| Feature | Cetirizine (Cet10) | Diphenhydramine (Benadryl) |
|---|---|---|
| Generation | Second-generation | First-generation |
| Common Side Effect | Less drowsy | Significantly more sedating |

It provides 24-hour relief from conditions like hay fever and hives with less drowsiness than older antihistamines.
