Cetrizine syrup is formulated for use in children and humans, and there is no established safety or dosage information for giving it to a parrot.

⚠️ Potential Risks and Precautions

• Birds have very different metabolisms and sensitivities compared to humans, so medicines safe for humans can be harmful or toxic to them.
• Even a small dose such as one drop could cause unexpected side effects or toxicity in your parrot.
• Antihistamines like cetirizine are not typically recommended for birds without specific veterinary guidance.

🩺 Recommendation

Please consult an avian veterinarian before giving any human medication, including cetirizine syrup, to your parrot. They can advise on safe treatments for allergies or other conditions in birds.
