Clear answers about the medicines you already take
Doctors are busy and pharmacy counters are rushed. An online consultation with a pharmacist gives you time to ask every question, in plain language.
“Is this headache from my new tablets?”
Side effects
Which symptoms usually settle, which need a call to your doctor, and what you can do in the meantime.
“Can I take ibuprofen with my blood pressure pills?”
Drug interactions
Prescription medicines, over-the-counter products, vitamins and herbal remedies checked together, not one at a time.
“What does this new diagnosis mean for me?”
Understanding your diagnosis
What your condition means, what each medicine is doing for it, and the questions worth taking to your next appointment.
“What are my options besides HRT?”
Menopause and women’s health
Hot flushes, sleep and mood, questions about hormone therapy, and which researched plant-based options are worth discussing.
“Should I take this with food?”
Lifestyle and plant-based options
Food, timing, exercise and well-researched natural options that can work alongside your treatment, never instead of it.
People who want to understand their medicine, not just take it
- You take several chronic medicines
Blood pressure, cholesterol, diabetes, thyroid or pain medication, and you’re not sure how they all fit together.
- You care for an ageing parent
You want someone to look over their whole list, explain it to the family and flag what to raise with their doctor.
- You’ve just been diagnosed
You left the consulting room with a script and a leaflet, and now you have questions.
- You’re going through menopause
You’d like an unhurried conversation about symptoms, treatments and natural options.
Three steps, all from home
No travel and no waiting room. Just you, your medicines and an experienced pharmacist.

What a consultation is, and what it isn’t
Willem helps you understand and organise your medicines. Your doctor stays in charge of diagnosing and prescribing.
A consultation covers
- What each of your medicines is for and how to take it
- Side effects and interactions, including supplements
- Clear questions to take to your doctor
- Lifestyle, diet and researched natural options
It does not replace
- Your doctor’s diagnosis, prescription or physical examination
- Changing or stopping medicine without your doctor
It does not replace emergency care. In an emergency call 10177 or go to your nearest emergency unit.

Painkillers, flu remedies and herbal products you can buy without a script can interfere with blood pressure, heart and blood-thinning medicines.

Does this replace my doctor?
No. Willem doesn’t diagnose, prescribe or change your medicine. He helps you understand it and prepare clear questions to take to your doctor.
What does it cost?
The 15-minute meet & greet is free. If a full consultation would help, Willem tells you the fee upfront, before you commit to anything.
How do the online meetings work?
By video call or phone, from wherever you are in South Africa. You’ll get a link or a call at the time you agree on.
What should I have ready?
Your medicine boxes or a list of everything you take, including vitamins, supplements and anything bought without a prescription, plus a notebook for your questions.
Is my information kept private?
Yes. Your details are handled under POPIA, used only to prepare for and give your consultation, and never sold or shared for marketing.
Does ABC-Z Virtual sell medicine or supplements?
No. ABC-Z Virtual is an advice service only. Nothing is sold through it.
