Azithromycin in Australia: What You Need to Know

Azithromycin is a popular antibiotic that doctors in Australia prescribe for a range of bacterial infections – from chest infections to skin infections and sexually transmitted diseases. It belongs to the macrolide class, which means it works by stopping bacteria from growing, not by killing them instantly. If you’ve been handed a script for azithromycin, you probably have questions about how to take it, what side effects to expect, and how much it will cost. Below we break it all down in plain English.

How to Take Azithromycin – Dosage Basics

In Australia the usual adult dose for most infections is 500 mg once daily for three days, or a single 1 g dose for certain sexually transmitted infections. Kids get a weight‑based dose, typically 10 mg per kilogram of body weight once daily for three days. Always follow the exact schedule on your prescription – missing a dose can let the infection bounce back.

Take the tablet with a glass of water. You don’t have to eat before or after, but if your stomach feels upset, a small snack can help. The medication stays in your system for a while, so you might keep feeling its effects for a few days after the last pill.

Safety, Side Effects & Interactions

Azithromycin is generally well‑tolerated, but a few side effects pop up fairly often: mild stomach upset, diarrhoea, or a temporary change in taste. Less common reactions include rash, headache, or a rapid heartbeat. If you notice severe dizziness, trouble breathing, or a high fever, call your doctor right away – these could signal a rare allergic reaction.

Medication interactions matter. Azithromycin can boost levels of certain heart drugs (like some statins) and may affect blood thinners such as warfarin. Always tell your pharmacist about any other medicines you’re using, including over‑the‑counter supplements.

People with liver disease, certain heart rhythm problems, or a history of allergic reaction to macrolide antibiotics should discuss alternatives with their doctor before starting azithromycin.

Pregnancy and breastfeeding? Azithromycin is considered safe in most cases, but it’s still worth a quick check with your healthcare provider.

How Much Does It Cost and Where to Get It?

The price of azithromycin in Australia varies by pharmacy and whether you have a PBS (Pharmaceutical Benefits Scheme) subsidy. With PBS, a three‑day course can be as low as $5‑$10. Without subsidy, you might pay $20‑$30 for a standard pack. Online pharmacies often advertise cheaper rates, but be cautious – only use sites that are TGA‑registered and require a valid prescription.

If you need a refill, your doctor can send a new script directly to your chosen pharmacy. Some Australian pharmacies also offer a “quick pick‑up” service where you can collect the medication in under an hour.

Remember, buying antibiotics without a prescription is illegal and risky. Unregulated sources may sell counterfeit pills that don’t work or could be dangerous.

In short, azithromycin is an effective tool against many bacterial infections when used correctly. Follow the dosage instructions, watch for side effects, keep your doctor in the loop about other meds, and only obtain it from a reputable pharmacy. Doing so ensures you clear up the infection quickly and stay safe.
