1. Contamination and non-sterile injection
The most common serious harm is infection: an abscess at an injection site, cellulitis, or in the worst cases a bloodstream infection. It comes from non-sterile product, non-sterile technique, reused needles or vials handled carelessly. This risk is concentrated almost entirely in unregulated supply, and it is mechanical rather than pharmacological — which means it is preventable.
2. Dosing errors from unit confusion
Reconstitution and measurement in insulin syringe units is where tenfold errors happen. Someone calculating their own dose from a forum post, with a vial of unknown concentration, using a syringe graduated in units rather than millilitres, is the archetype. A prescription that states the concentration and the volume to draw, with someone to check it, removes this category.
3. Missing the condition underneath
Treating fatigue as a hormone problem when it is sleep apnoea, anaemia, thyroid disease, depression or something that needed investigating. The harm here is delay, and it is invisible because nothing dramatic happens — the person simply does not get better, and the real diagnosis arrives later than it should have.
4. Unmonitored therapy
Testosterone therapy that raises haematocrit with nobody checking. A growth hormone secretagogue nudging glucose regulation with nobody looking. These are slow, silent and entirely detectable if someone is measuring. A service that prescribes without a retest schedule has removed the only mechanism that would catch them.
5. Interactions and life events
A new prescription from another doctor, a planned surgery, a pregnancy or an attempt to conceive, a new diagnosis. Each can make a protocol that was appropriate last month inappropriate this month. This is the argument for one physician who holds the whole picture, and for telling them things that feel unrelated.
When to stop and seek care now
Difficulty breathing, swelling of the face, lips or tongue, or a widespread rash — stop and get emergency care. Severe or persistent abdominal pain, particularly radiating to the back with vomiting. Spreading redness, warmth or discharge at an injection site, or fever. Chest pain, sudden severe headache, or one-sided weakness or visual change. None of these are things to message about tomorrow.
Key points
- Infection, unit-confusion dosing errors, missed diagnoses, no monitoring, interactions.
- Four of the five are eliminated by a prescriber, a pharmacy and a retest schedule.
- Breathing trouble, facial swelling or spreading redness is an emergency.
