Stop guessing your meds: a clinician's guide to safe self-care

You wake up with a sore throat. Your colleague swears by amoxicillin. The pharmacy down the road sells it without a prescription. Two days later you feel better, you stop the course — and three weeks later, the same infection comes back, harder to treat.

This sequence is so common in West Africa that the WHO has flagged it as one of the leading drivers of antibiotic resistance on the continent. The fix isn't to never self-care — it's to know the line.

What 'self-medication' actually means

Reaching for paracetamol when you have a tension headache is self-care, and it's fine. Buying a five-day course of antibiotics because someone said it worked for them is self-medication, and it's the problem. The difference comes down to whether the medicine has a clear, verifiable indication for what you're feeling.

“If a medicine needs a diagnosis to work, it needs a clinician to prescribe.”

When over-the-counter is fine

Pharmacists are trained, accessible clinicians and the corner pharmacy is often the right first stop. For mild, short-lasting symptoms with no warning signs, OTC analgesics, antihistamines, antacids and oral rehydration salts are all reasonable choices.

Five red flags that need a clinician

These aren't subtle. If any apply, don't try to manage the situation from your medicine cabinet:

1. 1
   Fever above 39 °C lasting more than 48 hours

   Especially in children under 5, the elderly, or anyone with a chronic illness.
2. 2
   Pain that wakes you up at night

   Pain bad enough to break sleep often points to inflammation or infection that needs assessment.
3. 3
   Symptoms after a new medicine

   Rash, swelling, breathlessness or sudden mood change after starting any drug — stop and call a clinician.
4. 4
   Bleeding that isn't expected

   Blood in stool, vomit or urine, or a nosebleed lasting more than 20 minutes is never something to wait out.
5. 5
   Same symptom returning a third time

   If a problem keeps coming back after 'feeling better', the underlying cause hasn't been treated.

How antibiotics get misused

Three patterns account for nearly every case of misuse we see at our clinics: stopping early because symptoms improve, sharing leftovers with family members, and buying antibiotics for viral illness — colds, most sore throats, and uncomplicated diarrhoea, which antibiotics cannot treat.

What to ask your pharmacist

Bring this list to the counter — pharmacists are trained for it and welcome the questions: what is this for, how should I take it, what does it interact with, and what should make me stop and call back?

When to talk to a doctor instead

If you're managing a chronic condition (hypertension, diabetes, asthma), starting any medicine that requires monitoring (steroids, blood thinners), pregnant or breastfeeding, or if a symptom has lasted more than five days, the right first step is a doctor — not a pharmacy shelf.
