“People deserve more than just instructions on a prescription label. They deserve to understand what’s happening inside their body — and why.”
Donna Brettler is a seasoned Australian pharmacologist and medical writer with over 20 years of experience in pharmacy and public health. Educated at the University of Sydney and Monash University, she’s known for making medical information crystal clear, compassionate, and trustworthy. As one of the leading authors at AntiinfectiveMeds.com, Donna helps thousands of readers better understand the medicines they take and the conditions they face — with confidence, not confusion.
Born and raised in the vibrant coastal city of Newcastle, Australia, Donna Brettler grew up watching her grandfather struggle with chronic infections, always confused by the stack of medicines on his nightstand. Nobody explained anything to him. And Donna — sharp, curious, and full of questions — noticed.
That confusion sparked a lifelong mission: to bridge the gap between the medical world and the people it’s meant to serve.
Donna holds a Bachelor of Pharmacy from the University of Sydney, one of Australia’s leading institutions. Later, driven by a desire to create a broader health impact, she earned her Master of Public Health (MPH) from Monash University.
Donna has worked in both public hospitals and private clinics. From advising GPs on complex drug regimens to helping parents understand antibiotics for their children, she has seen it all — and she brings that layered perspective to every word she writes.
You won’t find cold, robotic jargon in Donna’s articles. Her readers often say it feels like a good friend who happens to be a medical expert is explaining things to them. That’s because she writes the way she speaks — with clarity, empathy, and zero judgment.
Her passion? Making complex health topics feel simple, human, and actionable.
Whether it’s about antibiotic resistance, choosing the right medication for an infection, or understanding side effects — Donna knows what readers really want to know. And she answers the questions that no one else thinks to ask.
Today, Donna is one of the driving forces behind AntiinfectiveMeds.com — a fast-growing, reader-friendly blog dedicated to helping people make smart, safe decisions about medications.
She doesn’t just contribute articles. She helps shape the direction of the blog, digging into the real concerns that everyday people have about treatments, diseases, and pharmaceutical safety.
“Our readers aren’t looking for another academic paper. They want truth, clarity, and confidence in the choices they make for themselves and their families. That’s what we give them.”
Away from her desk, Donna is a mother of three, a fierce advocate for antibiotic awareness, and an unapologetic tea lover. She’s the kind of person who’ll stop mid-conversation at a dinner party to explain what “broad-spectrum” really means if someone looks confused. Because, to her, sharing knowledge is a form of care.
When Donna writes, it’s never just content — it’s a conversation that could change someone’s health journey.
If you’ve ever felt overwhelmed by medical terms or unsure about what’s going into your body, Donna’s articles will feel like a breath of fresh air.
