Understanding Common Pain Medicines

Not all pain medicines work the same way, and that is worth understanding when you are the one taking them.

Which medicine suits you depends on the cause of your pain, your overall health, your other conditions and your personal goals. It is common to take more than one, because different medicines target different things: one might ease inflammation, another calm nerve pain, another help sleep. Knowing why you have been prescribed a particular medicine helps you use it well and have clearer conversations with your team.

Paracetamol

Paracetamol is one of the most widely used pain medicines. It is often recommended for mild pain and may help with some musculoskeletal conditions, meaning pain from muscles, joints and bones. It is generally well tolerated at the recommended dose and is sometimes used alongside other medicines.

That said, on its own it is unlikely to provide much relief for persistent pain.

Anti-inflammatory medicines (NSAIDs)

NSAIDs, non-steroidal anti-inflammatory drugs such as ibuprofen, naproxen and celecoxib, reduce inflammation and can ease pain linked to inflammatory conditions or acute injuries. Where inflammation is contributing to persistent pain, they may improve comfort and function for some people.

They are not right for everyone, though. Long-term use can raise the risk of stomach ulcers, kidney problems and cardiovascular complications, and they can interact with other medicines. Your healthcare team will help work out whether they suit you.

Opioids

Opioids include medicines such as oxycodone, morphine, tapentadol and buprenorphine. They can be very effective for acute pain, pain after surgery, and cancer-related pain.

For persistent non-cancer pain, the benefits are often more limited, especially over long periods. Some people gain meaningful improvements in function; others develop tolerance, meaning the same dose works less well over time, or experience side effects that outweigh the benefit. If opioids are prescribed, they should be reviewed regularly to make sure they keep doing more good than harm.

Adjuvant medicines

Some medicines were first developed for other conditions but turn out to help certain kinds of persistent pain. These are called adjuvant medicines, and they include some antidepressants, some anti-seizure medicines, and other medicines that influence nerve signalling.

When prescribed for pain, these are not treating depression or epilepsy. Instead, they change how the nervous system processes pain signals, which can be especially helpful for neuropathic (nerve-related) pain.

Choosing the right medicine

There is no single best pain medicine. The right one depends on your circumstances: the type of pain you have, your other conditions, the other medicines you take, how you have responded to treatments before, and your goals and priorities.

Your healthcare team weighs all of this when recommending treatment, and finding the right combination sometimes takes some adjustment over time. The next article looks at how to use these medicines safely and how to recognise when a review is needed.

KEY TAKEAWAY

Different pain medicines work in different ways, and many people use more than one because each targets a different part of the problem. There is no single best medicine; the right choice depends on your pain type and circumstances, and every medicine needs regular review of its benefits against its risks.
