Atrizin 10mg Tablet — Cetirizine Antihistamine by Beximco

Atrizin 10mg Tablet — Cetirizine | Beximco Pharmaceuticals

Overview

Atrizin 10mg contains Cetirizine, a potent second-generation antihistamine. Unlike first-generation antihistamines (chlorphenamine, promethazine), Cetirizine causes minimal sedation and has no significant anticholinergic effects. It provides 24-hour allergy symptom relief. Diabetic patients with allergic conditions can generally use Cetirizine safely, as it does not significantly affect blood glucose or interact with major antidiabetic agents.

Mechanism of Action

Cetirizine is a selective peripheral H1 histamine receptor antagonist. It competitively blocks histamine at H1 receptors in blood vessels, bronchi, and the gastrointestinal tract, preventing histamine-mediated allergic responses. Its poor CNS penetration (due to its zwitterionic nature) explains the low sedative profile compared to first-generation antihistamines. It also has mild anti-inflammatory properties beyond simple H1 blockade.

Indications

• Allergic rhinitis (seasonal — hay fever; perennial)
• Allergic conjunctivitis
• Urticaria (hives) — acute and chronic idiopathic
• Atopic dermatitis / eczema (adjunct)
• Angioedema (non-hereditary, allergic)
• Insect bite reactions
• Drug hypersensitivity reactions (mild)

Dosage

Take with or without food. Evening dosing may reduce any residual sedation during daytime activities.

Diabetic Patient Information

• Blood glucose: Cetirizine does not significantly affect blood glucose levels — generally safe in diabetics
• Renal dose adjustment: Diabetic nephropathy with eGFR 11–30 ml/min — reduce to 5mg once daily; avoid if eGFR <10 ml/min
• Dry mouth caution: Cetirizine has mild anticholinergic effects — can worsen dry mouth, which is already common in diabetics. Maintain oral hygiene and hydration
• Sedation caution: Although non-sedating at standard doses, some patients may experience mild drowsiness. Avoid driving if affected — especially important for diabetics who may already experience hypoglycaemia-related impairment
• Diabetic skin conditions: Pruritus (itching) is common in diabetes. While antihistamines may provide some relief, persistent or severe skin symptoms in diabetics should be evaluated — itching may indicate poor glycaemic control, kidney disease, or nerve damage

Side Effects

Contraindications

• Known hypersensitivity to cetirizine, hydroxyzine, or excipients
• Severe renal impairment (eGFR <10 ml/min)
• Caution in prostatic hypertrophy or urinary retention

Drug Interactions

Cetirizine has minimal clinically significant drug interactions. Alcohol and CNS depressants may enhance sedation. No significant interactions with antidiabetic drugs, antihypertensives, or common diabetes medications.

Storage

Store below 30°C. Protect from light and moisture. Keep out of reach of children.

Medical Disclaimer: Atrizin 10mg (Cetirizine) is an antihistamine. Diabetic patients with renal impairment require dose reduction. Persistent skin itching in diabetics should be medically evaluated — it may indicate underlying glycaemic or renal issues.
