Recognising Side Effects and When to Act

Side Effects Aren’t Always Obvious
It’s easy to assume that new symptoms are just part of ageing. But many signs — from drowsiness to confusion — may actually be side effects of your medication. Recognising and reporting them early is one of the most important ways to stay safe and independent.
Common Side Effects in Older Adults
- Drowsiness or dizziness – increases fall risk
- Confusion or memory lapses – sometimes mistaken for early dementia
- Dry mouth or constipation – often caused by painkillers or antidepressants
- Loss of appetite or weight changes
- Sleep changes – especially with blood pressure or mental health medicines
These side effects can develop slowly and may not appear immediately after starting a medicine.
What’s the Difference Between a Side Effect and a Serious Reaction?
Side effects are known, expected outcomes listed on your medicine leaflet. They’re often manageable but should still be reported if they’re new or worsening.
Serious or allergic reactions need urgent help. These include:
- Rash, swelling, or difficulty breathing
- Severe dizziness or fainting
- Unusual bleeding or bruising
- Chest pain or heart palpitations
📞 If you suspect a serious reaction, call 111 or speak to your GP immediately.
How to Track Your Side Effects
- Keep a small diary or notebook nearby.
- Note the time, date, and how you felt before and after taking each medicine.
- Share this log with your pharmacist or GP — it helps spot patterns and avoid unnecessary worry.
Don’t Suffer in Silence
Many older adults hesitate to mention side effects because they don’t want to “bother” anyone. But your health team wants you to speak up — no symptom is too small to ask about. You may need an adjustment, an alternative, or extra support.
