11086 Non Steroidal Anti Inflammatory Medicines Nsaids

Overview

NSAIDs are a large family of medicines used to ease pain, bring down fever and reduce swelling. The name breaks down like this: 'non-steroidal' means they do not contain steroids, and 'anti-inflammatory' means they calm down swelling and irritation in the body. They work by blocking a natural enzyme (a body chemical) called COX, which the body makes when there is injury or inflammation. Blocking it lowers the chemicals that cause pain and swelling, but it can also affect the stomach lining, kidneys and blood vessels — which is why how you use them matters. Some NSAIDs are sold over the counter in pharmacies and shops, and others are only available on prescription. They come as tablets, capsules, liquids, creams, gels and injections.

Very common. NSAIDs are used by millions of people every day around the world, and most people take them without any problems. They are one of the most frequently prescribed groups of medicines by family doctors, and several are available to buy without a prescription.

Anyone can use NSAIDs, but the risk of side effects is higher in some groups: older adults (roughly over 65), people with a history of stomach or bowel ulcers or bleeding, people with kidney, liver or heart problems, people with high blood pressure, people who take blood-thinning or steroid medicines, people who are dehydrated, and people in the later stages of pregnancy. Children can take some NSAIDs, but only at doses worked out for their weight and age, and with advice from a pharmacist or doctor.

Symptoms

Common symptoms

• Indigestion, heartburn or a sore, burning feeling in the upper tummy
• Nausea or feeling sick, sometimes with mild tummy pain
• Headache or dizziness
• Mild swelling of the ankles or feet from fluid retention
• A rash or itching in some people
• Feeling more tired than usual
• The problem being treated — such as pain or swelling — easing within a few hours of a dose

Symptoms in children

• Some NSAIDs are used for children with fever or pain, but only at doses based on the child's weight — ask a pharmacist or doctor first
• Children who are dehydrated (for example with a vomiting bug) are at higher risk of kidney strain, so these medicines are usually avoided at those times
• Some NSAIDs are not recommended in children with chickenpox or during certain illnesses — check with a pharmacist
• Watch for tummy pain, vomiting, unusual sleepiness, or passing much less urine than usual

Symptoms in older adults

• Higher chance of stomach and bowel irritation or bleeding, sometimes without much warning pain
• Higher chance of kidney strain, especially if you are dehydrated or unwell with another illness
• A greater chance of raised blood pressure or fluid build-up affecting the heart
• More likely to be taking other medicines that interact with NSAIDs, such as blood thinners, blood pressure medicines or steroids
• Confusion or worsening of an existing illness can be a sign of a problem — get medical advice early

Causes

Main causes

• This is a group of medicines, not an illness, so there is no cause as such — but the chance of harm depends on how the medicine is used.
• Taking more than the recommended amount, or taking it more often than advised.
• Taking an NSAID for longer than needed, especially for weeks or months.
• Taking two NSAIDs at the same time — often by accident, when a cold remedy or combined pain product also contains one.
• Taking an NSAID alongside other medicines that irritate the stomach or thin the blood.
• Being dehydrated, or being unwell with another illness that puts strain on the kidneys.

Risk factors

• Being over about 65 years old
• A previous stomach or bowel ulcer, or previous bleeding in the gut
• Kidney, liver or heart problems, including heart failure
• High blood pressure
• Asthma, particularly a type linked with nasal polyps or a history of reaction to these medicines
• Taking blood thinners, steroid tablets, or certain medicines for low mood
• Smoking or drinking a lot of alcohol
• Being in the later stages of pregnancy
• Using NSAID gels or creams on large areas of skin while also taking tablets

When to see a doctor

See a doctor urgently if:

• You have severe tummy pain, vomiting, or any blood in your vomit or stools — seek emergency care if bleeding is heavy
• You develop swelling of the face or throat, or trouble breathing
• You notice you are passing much less urine than usual
• Your ankles or legs swell, or you become breathless more easily
• You have a long-term condition and are unsure whether an NSAID is safe for you
• You are pregnant or breastfeeding and thinking of taking one

Book a routine appointment if:

• You find you need pain relief most days for more than a couple of weeks
• You are taking an NSAID regularly and have not had a medicine review in the last year
• You have new indigestion or heartburn after starting the medicine
• You want to know whether a gel or cream would suit you better than tablets
• You have several health conditions or take several medicines and want a medicines check
• You are planning to buy a cold or flu remedy and want to check it does not contain an NSAID

Diagnosis

There is no test for 'being on an NSAID'. Instead, your doctor or pharmacist assesses whether the medicine is right and safe for you. They will ask what you are taking, how much and how often, how long you have taken it, what other medicines and supplements you use, and whether you have any conditions that raise your risk. If you have side effects or are taking NSAIDs long term, they may arrange simple tests. Diagnosis here really means a careful medicine review.

Tests that may be done

• A blood test to check kidney and liver function
• A full blood count to look for anaemia, which can be a sign of slow bleeding in the gut
• A stool test if bleeding in the bowel is suspected
• A blood pressure check
• A review of all your medicines, including anything bought without a prescription
• A referral to a specialist or an endoscopy (a camera test of the stomach) if a stomach problem is suspected

What to expect at your appointment

A medicine review is usually a short conversation, either at the pharmacy or with your doctor. Bring a list of everything you take, including remedies you buy yourself, vitamins and herbal products, and note how often you actually take them. Your clinician may suggest a different pain relief option, a lower amount, a shorter course, a gel instead of tablets, or an extra medicine to protect your stomach. You should leave knowing exactly what to take, for how long, and what to watch for.

Treatment

NSAIDs are one option among many for pain and swelling — not the only one, and not always the best one. The safest approach is the smallest amount that works, for the shortest time that helps, at the lowest strength that controls your symptoms, and only when other measures are not enough. Many people get good relief from non-medicine approaches or from other types of pain relief that your pharmacist or doctor can discuss with you.

Self-care at home

• Take the medicine with or just after food, and with a drink of water, unless your clinician advises otherwise
• Follow the label exactly — do not take extra to get faster relief
• Check the labels of cold, flu and combined pain products so you do not accidentally take two NSAIDs
• Keep a simple diary of what you take, when, and how much it helps; bring it to appointments
• For muscle and joint pain, try rest, ice or warmth, gentle movement and pacing yourself before reaching for tablets
• Stay well hydrated, especially in hot weather or if you have a stomach bug
• Limit alcohol, as it increases the risk of stomach irritation and bleeding
• Stop and get advice if you develop tummy pain, black stools or new swelling

Medical treatments

Your clinician will consider which type of pain relief is safest for you, in what form, and for how long. Options include tablets or capsules, liquids, creams and gels rubbed into the skin (which have less effect on the stomach), and injections for specific situations. For short courses, taking the medicine with food and using the lowest effective strength is usual. For people at higher risk of stomach problems, a doctor may add a medicine that protects the stomach lining, or may recommend a different pain relief approach altogether. Regular reviews are important if you take these medicines long term — for example for arthritis — so the plan can change if your health, medicines or symptoms change. Other approaches, such as physiotherapy, exercise programmes, weight management and pain-management support, are often part of the picture. Never start, stop or change a medicine without advice from your clinician or pharmacist.

Living with this condition

Living well with a medicine like this is mostly about good habits and good information. Know exactly which product you are taking, keep it in its original packaging, and tell every doctor, nurse, dentist and pharmacist that you take it — especially before any procedure. If you use it only now and then, keep track so you can answer 'how often?' at appointments. Ask your pharmacist for a yearly medicines check if you take it regularly. Keep a note of side effects and tell your clinician rather than just putting up with them.

Lifestyle tips

• Stay physically active in ways that suit you — gentle strength, walking and stretching can reduce the need for pain relief over time
• Cut down or stop smoking, which slows healing and adds to heart and stomach risk
• Keep alcohol within low-risk levels and avoid heavy drinking while taking these medicines
• Drink water regularly through the day
• Aim for a healthy weight, which eases load on joints and lowers heart and kidney strain
• Protect your sleep — tiredness makes pain feel worse
• Have a simple home system for your medicines, such as a weekly pill organiser or a phone reminder

Diet and exercise

Eating regular meals and taking your medicine with food reduces stomach upset. A balanced diet with plenty of fibre and fluids keeps your digestion comfortable, particularly if pain relief slows your bowels. Exercise is one of the most effective long-term pain treatments for joint and back pain: start gently, build up slowly, and choose something you enjoy — swimming, walking, cycling or chair-based exercise all count. A physiotherapist or your GP can help you plan something safe for your body.

Mental health and emotional wellbeing

Ongoing pain is tiring and can wear down your mood, sleep and confidence. Needing pain relief often can also cause worry about the medicine itself. Those feelings are common and worth talking about. Tell your clinician if you feel low, anxious or hopeless — support is available, and treating mood and sleep often helps pain feel more manageable. If you ever feel unable to cope, please reach out to a crisis line in your country or your local emergency services straight away.

Prevention

You cannot prevent side effects completely, but you can greatly reduce the risk. Use the smallest amount that works for the shortest time, take it with food, avoid combining two NSAIDs by checking labels carefully, keep alcohol low, stay hydrated, and ask your pharmacist to check for interactions with your other medicines. Tell your clinician if you have had a stomach ulcer, kidney problem or heart problem before starting. Have your medicines reviewed regularly if you take them long term.

Screening programmes

There is no screening programme for NSAID use. Instead, the 'screening' is a medicines review: a blood test to check kidney and liver function and a blood count before or during long-term use, and a blood pressure check. Ask your clinician whether you are due one.

Complications

If left untreated

• Stomach or bowel ulcers, which can bleed — sometimes with little warning
• Kidney strain or kidney injury, particularly if you become dehydrated
• Raised blood pressure and fluid build-up, which can worsen heart failure
• Worsening asthma in some people
• Liver irritation, which is usually reversible when the medicine is stopped
• Interaction with other medicines, for example reducing the effect of some blood pressure treatments or increasing bleeding risk with blood thinners

Long-term outlook

The outlook is good for most people. Used sensibly — the right medicine, at the right amount, for the right length of time, with a review when needed — NSAIDs are a valuable and generally well-tolerated way to control pain and swelling. Serious problems are uncommon and are mostly linked to high amounts, long use, or mixing medicines without checking. If you are worried about anything you notice, contact your pharmacist or doctor; most issues are easier to sort out when raised early.
