Frequently Asked Questions

For hay fever and hayfever symptoms, including sneezing, runny nose, and itchy eyes, the most widely used non-drowsy antihistamines in Australia are Zyrtec (cetirizine), Claratyne (loratadine), and Telfast (fexofenadine). All three are available over the counter at Giant Chemist Harbour Town in tablets and liquid capsule formats.

Zyrtec is fast-acting and available in tablets and liquid capsules. Claratyne is non-drowsy and suitable for both adults and children. Telfast is available in 120mg and 180mg formulations. For nasal congestion alongside hayfever, Rhinocort or Nasonex nasal spray may be more effective. Our pharmacists in-store can help you choose the right option for your symptoms.

For children aged 2 and over, Claratyne Children's antihistamine is widely regarded as the best antihistamine for children in Australia. It is available as a non-drowsy syrup (peach and grape flavour) and as bubblegum or grape-flavoured chewable tablets for children 2+. Both provide 24-hour relief from hayfever, year-round allergies, and hives (urticaria). Always check the age and weight dosage guidelines on the packaging, and consult your pharmacist if you are unsure which formulation is right for your child.

Yes, antihistamines are commonly used to help relieve itching associated with skin rashes, hives (urticaria), eczema, and dermatitis. Telfast Skin Rash & Hayfever Tablets (fexofenadine 180mg) are specifically indicated for chronic hives and skin rash relief in adults. Claratyne and Zyrtec tablets are also used for itch relief associated with hives and allergic skin conditions. Antihistamines address the itch and histamine response but are not a treatment for the underlying skin condition. If symptoms are ongoing or severe, consult a pharmacist or doctor.

For mild to moderate allergic reactions to bee stings or insect bites, such as localised swelling, redness, and itching, an oral antihistamine tablet such as Zyrtec, Claratyne, or Telfast can help reduce symptoms quickly. For immediate relief of a bee sting reaction, a fast-acting option such as Zyrtec liquid capsules may be preferred. Note: Antihistamines are suitable for mild localised reactions only. If someone experiences signs of a severe allergic reaction (anaphylaxis) such as difficulty breathing, throat swelling, or loss of consciousness, call 000 immediately.

Yes, Zyrtec Levocabastine Eye Drops are available over the counter at Giant Chemist Harbour Town without a prescription. They provide targeted, rapid relief from itchy, watery eyes caused by hayfever and allergies. Antihistamine eye drops are particularly useful when eye symptoms are the primary complaint, and can be used alongside an oral antihistamine if other allergy symptoms are also present. Our pharmacists can advise on the most appropriate combination for your symptoms.
