Almost everyone reaches for a painkiller now and then. A stiff back after a day in the garden, a headache that will not shift, a flare of arthritis in the knees. In Ireland, paracetamol and ibuprofen live in most kitchen presses, and because they are so easy to buy we treat them as harmless. After 50 that assumption deserves a second look. The medicines have not changed, but our bodies have, and a tablet that was unremarkable at 35 can behave quite differently at 65.
This is not an argument for putting up with pain, which wrecks sleep and pushes people away from the exercise and social contact that keep them well. The goal is the right medicine, at the right dose, for the right length of time.
TL;DR
- Ageing kidneys, a thinner stomach lining and a longer medication list all change how painkillers behave after 50, even at unchanged doses.
- Paracetamol is the sensible first step for most everyday pain, but check cold and flu remedies so you are not doubling up.
- Anti-inflammatories (ibuprofen, naproxen, diclofenac) carry the biggest age-related risks: stomach bleeding, kidney injury, raised blood pressure and worsening heart failure.
- The “triple whammy” of an NSAID plus an ACE inhibitor or ARB plus a water tablet is a recognised cause of sudden kidney damage.
- Topical gels, a free pharmacist medicines review and the HSE Chronic Disease Management Programme are the practical places to start in Ireland.
Why the same tablet hits differently after 50
Kidney function declines from midlife onwards, so medicines cleared by the kidneys hang around longer. The protective mucus layer in the stomach thins, which matters enormously for anti-inflammatories. And the average person over 65 in Ireland takes several regular medicines, so every new painkiller lands in a busier system.
Irish research has led the field here. The STOPP/START criteria, developed at University College Cork, are used internationally to flag medicines that are potentially inappropriate for older adults. Several pain medicines appear on that list, not because they are bad drugs, but because the risk-to-benefit balance tips as we age.
Paracetamol: the quiet workhorse
For most everyday aches, paracetamol is still the sensible starting point. It does not irritate the stomach, it does not affect the kidneys the way anti-inflammatories do, and it plays well with most other medicines including blood thinners.
The usual adult maximum is 4 grams a day, eight 500mg tablets, with at least four hours between doses. Lower doses are advised for people under 50kg, with liver problems, or who drink regularly. The gap between a safe dose and a harmful one is narrower than most people assume.
The commonest mistake is accidental doubling up. Paracetamol hides inside cold and flu sachets, night-time remedies and co-codamol, so you can exceed the daily limit without ever opening the paracetamol box.
Anti-inflammatories: where the real risk sits
Ibuprofen, naproxen and diclofenac are excellent at reducing inflammation, which is why they help with arthritis, gout and injuries. They also carry the clearest age-related risks of any common painkiller.
Regular NSAID use raises the risk of stomach ulcers and gastrointestinal bleeding, and that risk climbs steeply with age. NSAIDs reduce kidney blood flow, raise blood pressure, cause fluid retention, and can tip someone with borderline heart failure into a hospital admission. Combined with warfarin, a direct oral anticoagulant or an SSRI antidepressant, they increase bleeding risk considerably.
The combination worth knowing by name is the “triple whammy”: an NSAID alongside an ACE inhibitor or ARB (medicines like ramipril or losartan) and a diuretic. That trio is a well-documented cause of acute kidney injury, and it is easy to stumble into if you buy ibuprofen yourself.
None of this puts NSAIDs off limits. It means the lowest effective dose for the shortest time, and a conversation first. If you need them regularly, your GP may prescribe a stomach-protecting medicine alongside.
Try topical before oral
For localised joint pain, particularly knees and hands, anti-inflammatory gels are genuinely underused. Far less of the drug reaches the bloodstream, so stomach and kidney risks drop substantially while the local benefit holds up. For osteoarthritis in one or two joints, a gel plus paracetamol often does the job.
Codeine and stronger opioids
Codeine products sit behind the pharmacy counter in Ireland for good reason. Under Pharmaceutical Society of Ireland guidance they are supplied only after a conversation with the pharmacist, and are intended for short-term use of no more than three days.
Codeine must be converted by the liver into morphine, and people vary enormously in how efficiently they do this. The side effects, though, are dependable: constipation, drowsiness, and unsteadiness that raises falls risk. Taken frequently for headaches, it can also cause medication-overuse headache, where the treatment quietly becomes the cause.
Stronger opioids such as tramadol, morphine and oxycodone have a clear role in cancer pain and short-term severe pain after surgery or fracture. For long-term non-cancer pain the evidence for benefit is much weaker than most people expect, while the risks of falls, confusion and dependence are real. If you have been on one for months and it no longer seems to help, raise it with your GP, but never stop abruptly: opioids need a planned taper.
Nerve pain is a different animal
Burning, shooting or electric-shock pain from sciatica, shingles or diabetic neuropathy responds poorly to ordinary painkillers. Gabapentin, pregabalin, amitriptyline and duloxetine are used instead. They take weeks rather than hours to work, and all can cause drowsiness and dizziness, so falls prevention matters when starting a dose.
Practical steps you can take in Ireland
- Book a medicines review. Bring everything you take, including over-the-counter products, supplements and herbal remedies, to your community pharmacist in one bag. It is free and regularly catches duplications and interactions.
- Use the Chronic Disease Management Programme. With a medical card or GP visit card and a qualifying condition, structured reviews with your GP are covered.
- Know your entitlements. The Drug Payment Scheme caps monthly household spending on prescribed medicines, and medical card holders pay a small per-item charge subject to a monthly cap. Details on citizensinformation.ie.
- Report side effects. Anyone can report a suspected reaction to the Health Products Regulatory Authority at hpra.ie.
- Return what you do not need. Any Irish pharmacy will take back unused or out-of-date medicines for safe disposal.
When to stop self-treating
Get medical advice promptly for black or tarry stools, vomiting that looks like coffee grounds, pain that wakes you every night, unexplained weight loss, sudden leg swelling, new breathlessness, or passing noticeably less urine. See your GP too if you are reaching for painkillers on more days than not.
Pain lasting beyond three months deserves a broader plan than medication alone. Physiotherapy, graded activity and the self-management approaches offered through HSE pain services, Chronic Pain Ireland and Arthritis Ireland consistently outperform tablets on their own.
At Críonna Health we come back to the same principle: ageing well is the accumulation of small, informed decisions. Knowing what is in the box before you swallow it is one of them.
