The Self-Medication Balance
Over-the-counter medicines exist for a reason: most common ailments — a cold, mild fever, minor headache — are self-limiting and resolve on their own with a little help. Treating every sneeze with a doctor's appointment would overwhelm the healthcare system and your wallet.
But self-medication has limits. Delay in getting the right diagnosis can turn a treatable condition into a serious one.
When OTC Medicines Are Appropriate
You can safely self-medicate for:
| Condition | Recommended OTC |
| Mild fever (below 38.5°C) | Paracetamol |
| Common cold (runny nose, sore throat) | Antihistamine, saline nasal spray |
| Mild headache | Paracetamol or ibuprofen |
| Acidity or heartburn | Antacid |
| Minor cuts and scrapes | Antiseptic cream, bandage |
| Mild diarrhoea (in adults) | ORS, loperamide |
| Mild allergic reaction (sneezing, itching) | Antihistamine |
| Muscle strain | Ibuprofen, cold/warm compress |
Rule of thumb: If the symptom is mild, familiar, and improving — OTC treatment is reasonable.
Red Flags: See a Doctor Immediately
Go to a doctor or emergency room if you experience:
Fever
- Above 39.5°C in adults
- Any fever in a baby under 3 months
- Fever lasting more than 3 days
- Fever with stiff neck, rash, or confusion
Chest & Breathing

- Coughing up blood
Head & Neurological

Skin
- Spreading redness or warmth around a wound (infection)

- Rash with difficulty breathing (anaphylaxis — emergency)
Special Groups Who Should Be More Cautious
Some groups should consult a doctor before self-medicating:
- Pregnant women — many OTC medicines are unsafe in pregnancy
- Children under 2 — dosing is critical and many adult medicines are not safe
- Elderly adults — higher risk of drug interactions and side effects
- People with chronic conditions — diabetes, kidney or liver disease, heart conditions
- People on multiple medications — risk of drug interactions
The 48-Hour Rule
A practical guideline: if your symptoms are not improving after 48 hours of appropriate OTC treatment, or if they are getting worse at any point, see a doctor.
A Note on Antibiotics
Never self-medicate with antibiotics. Antibiotics:
- Do not treat viral infections (the common cold, flu, most sore throats)
- Require a prescription for good reason — misuse causes antibiotic resistance
- Can cause serious side effects if taken unnecessarily
If you have leftover antibiotics from a previous prescription — do not take them for a new illness without medical advice.
