What is Roxid 150mg?
Roxid 150mg is straight-up roxithromycin – the same antibiotic doctors have been prescribing in Australia for years. It belongs to the macrolide family (think a gentler cousin of erythromycin). Perfect when you’ve got a stubborn chest infection, raging tonsillitis, sinusitis that won’t shift, or a nasty skin infection. Most courses are 5–10 days and it starts working fast.
How does Roxid 150mg actually work?
Roxithromycin jumps in and stops bacteria from making the proteins they need to grow and multiply. No protein = bacteria die off, infection clears. It’s broad-spectrum, so it knocks out heaps of common bugs like Streptococcus, Staphylococcus, Haemophilus and Mycoplasma. Healthdirect has a good plain-English page on antibiotics if you want the official word.

Dosage & how to take it properly
Standard adult dose: one 150mg tablet twice daily (morning and night), about 12 hours apart.
Take on an empty stomach – at least 15 minutes before food or 3 hours after.
Finish the whole course even if you feel better after a couple of days.
Plenty of water, no alcohol while you’re on it.
Side effects – what to expect
Most people sail through with no drama. Possible mild ones:
- Bit of nausea or tummy ache
- Loose stools
- Funny taste in the mouth
Rare but serious: severe rash, bad diarrhoea or yellow skin/eyes – stop and ring your doctor straight away. The TGA keeps a close eye on roxithromycin generics – their info is worth a skim.
