Fexofenadine Australia: where to buy, how to use, and what to watch for

Need relief from hay fever or itchy hives? Fexofenadine is a go-to non-drowsy antihistamine many Australians use. Below you'll find clear advice on common doses, side effects, drug interactions, and how to buy it safely in Australia.

How to use fexofenadine

Fexofenadine treats allergic rhinitis (hay fever) and chronic urticaria (hives). Adults commonly take 60 mg twice a day or 180 mg once daily. Always follow the product label or a pharmacist's instructions — some brands offer different strengths. Take it with water. Don’t take it with fruit juice (orange, grapefruit, apple) because juices can reduce how much of the drug your body absorbs.

If symptoms don't improve in a few days or they get worse, check in with a pharmacist or GP. For children, doses depend on age and weight — use the pediatric product or ask a health professional for the right amount.

Side effects, interactions, and cautions

Most people tolerate fexofenadine well. The most common complaints are headache, mild nausea, and feeling tired, though drowsiness is less likely than with older antihistamines. Serious reactions are rare, but stop the medicine and seek help if you get a rash, swelling, or trouble breathing.

Key interaction to remember: avoid drinking fruit juice around the time you take your tablet. Also tell your pharmacist if you take other meds — while fexofenadine has few major interactions, it's smart to check if you're on strong antibiotics, antifungals, or other prescriptions. If pregnant, breastfeeding, or managing kidney problems, talk to your doctor before use.

Buying fexofenadine in Australia — practical tips

You can usually buy fexofenadine at community pharmacies and some supermarkets. Strengths and whether a prescription is needed can vary, so ask the pharmacist if you're unsure. If buying online, prefer Australian-registered pharmacies that show a real street address, a pharmacy registration number, and secure payment options.

Watch out for: extremely low prices, no contact details, or sites that pressure you to skip a doctor check. Real pharmacies let you consult a pharmacist and provide clear labels and expiry dates. If an online store ships from overseas, delivery times and returns can be tricky and product standards may differ.

Short tip: keep the pack insert. It lists dosage, side effects, and storage. If you ever mix up meds, call your local pharmacist — they're a quick, free resource and can save you time and worry.
