Psoriatic Arthritis Medications & Treatment
Psoriatic arthritis can affect joints, skin, tendon insertions, whole fingers or toes, and the spine. This is how I explain the treatment options in clinic, and how we decide together which one fits you.
Which part of the disease is loudest, and what we then discuss
This is a map of the conversation, not a prescription. Your own treatment depends on your examination, tests, other health conditions and your preferences.
Treatment targets more than one thing at a time.
When I treat psoriatic arthritis, I am not only looking at swollen joints. I look across the whole condition: the peripheral joints, the skin and nails, the tendon insertions (enthesitis), any sausage-like swelling of a finger or toe (dactylitis), and the spine and sacroiliac joints.
We agree a target together, usually remission or low disease activity, then review you at intervals and adjust if we are not getting there. That is what treat-to-target means in practice. Your function, your fatigue, your work and your own priorities are part of the assessment, not an afterthought.
Every step is a shared decision. I explain the options, what each one asks of you in terms of monitoring and precautions, and we choose together.
Anti-inflammatory medicines help symptoms, but they do not change the disease.
Non-steroidal anti-inflammatory medicines (NSAIDs) can settle pain and stiffness, and they have a genuine place, particularly early on or while we are waiting for a disease-modifying medicine to take effect. Local steroid injections are sometimes used for a single stubborn joint or tendon area.
I treat these as short-term and supportive. They do not stop joint or tendon damage, so they do not replace disease-modifying treatment when that is needed. NSAIDs also need care if you have kidney disease, stomach ulcers, high blood pressure or heart disease, so please do not simply buy them long term without a review.
Tablets that dampen the disease itself.
Conventional disease-modifying anti-rheumatic drugs include methotrexate, leflunomide, sulfasalazine and ciclosporin. They are usually taken by mouth, they act on the immune process rather than only on pain, and they take some weeks to show their benefit.
Methotrexate is commonly preferred when peripheral arthritis and significant skin psoriasis coexist, because it can help both. It is less helpful for spinal disease and less reliable for enthesitis, so the dominant pattern really matters when we choose.
These medicines need regular blood tests, and alcohol, pregnancy plans and other medicines all come into the discussion before we start.
Injected or infused medicines that block a specific pathway.
Biologics target one part of the immune pathway rather than dampening things broadly. In psoriatic arthritis the groups I discuss are:
- TNF pathway medicines, such as adalimumab, etanercept and infliximab.
- IL-17 pathway medicines, such as secukinumab and ixekizumab.
- IL-12/23 and IL-23 pathway medicines, which are particularly relevant when psoriasis of the skin is a major part of the picture.
A biologic is not a last resort. For some patients, especially when spinal disease, enthesitis or dactylitis dominates, it is the more suitable disease-modifying choice from the start. Before starting, we screen for infections including tuberculosis and hepatitis, and plan vaccines.
Tablets that act on specific signalling pathways.
JAK inhibitors, such as tofacitinib, upadacitinib and baricitinib, block intracellular signalling and are taken as tablets. They can help joints, enthesitis and spinal symptoms, and they suit some patients who prefer not to inject.
PDE4 inhibition is another oral approach, generally considered for milder disease and where a gentler immune effect is preferred. It is usually less potent for active, damaging joint disease.
With JAK inhibitors in particular, I go carefully through your age, smoking history, cardiovascular risk, clot risk and cancer history, because those factors influence whether this class is a good fit for you.
Two people with the same diagnosis can need very different treatment.
The things I weigh up with you include:
- Which domain dominates: peripheral joints, spine, enthesitis, dactylitis or skin and nails.
- How active and how widespread your psoriasis is.
- A history of uveitis, which makes some classes more suitable than others.
- Inflammatory bowel disease, which similarly narrows the choice.
- Infection risk, including recurrent infections, tuberculosis exposure and hepatitis.
- Cardiovascular risk, clot risk and any history of cancer.
- Pregnancy plans, breastfeeding, and fertility considerations.
- Other medicines and other conditions, such as kidney or liver disease.
- Your own preference between tablets, self-injections and hospital infusions, and what is practical for your life and budget.
Approvals and availability differ by medicine, by disease feature and by country. Not every medicine is approved for every feature of psoriatic arthritis, and what is available in Malaysia may differ from what you read online. I will tell you where your options stand.
The plan around the medicine matters as much as the medicine.
- Before starting: baseline bloods, and screening for tuberculosis and hepatitis for most biologics and targeted oral medicines.
- Vaccines: best planned before we start where possible. Live vaccines generally need to be avoided once you are on these medicines, so please check with me first, including before travel vaccines.
- Ongoing bloods: at intervals to check blood counts, liver and kidney function, with a schedule I will set out for your particular medicine.
- Infection precautions: tell me about fever, a persistent cough, shingles, or any infection needing antibiotics. Some medicines are paused during a significant infection or around surgery.
- Skin checks and sun care: worth keeping up, and I am happy to work alongside your dermatologist.
Please do not start, stop, swap or change the dose of any of these medicines without your treating clinician. Sudden changes can lead to a flare, and some medicines need specific timing around infections, surgery and pregnancy.

Treatment questions my patients ask me
Do I need a disease-modifying medicine, or can I just take painkillers?
Anti-inflammatory painkillers can settle symptoms for a while, and for very mild disease that may be enough for a short period. When there is ongoing joint inflammation, tendon inflammation, dactylitis or spinal involvement, painkillers alone do not change the course of the disease. In that situation I discuss a disease-modifying option with you, because the aim is to protect the joints and tendons over the long term.
What is treat-to-target?
It means we agree on a target together, usually remission or at least low disease activity, then review you at intervals and adjust treatment if we are not getting there. It is a shared decision each time, taking in how you feel, what I find on examination, your blood tests and your own priorities.
Why did you choose a different medicine for me than for someone else with psoriatic arthritis?
Psoriatic arthritis behaves differently in different people. The dominant pattern matters, whether that is peripheral joints, spine, enthesitis, dactylitis or skin and nails. Other things also shape the choice: uveitis, inflammatory bowel disease, infection risk, cardiovascular, clot and cancer history, pregnancy plans, other medicines, and your own preference between tablets and injections.
Is methotrexate still used in psoriatic arthritis?
Yes, it remains a common first disease-modifying choice for many patients, particularly when peripheral joint arthritis and significant skin psoriasis coexist, because it can help both. It is not the right first choice for everyone, and it is less useful for spinal disease.
Are biologics a last resort?
No. A biologic is sometimes the more suitable first disease-modifying medicine, for example when spinal disease or enthesitis dominates, or when conventional DMARDs are unsuitable. It is a considered choice, not a punishment for failing tablets.
Do these medicines lower my immunity?
Most disease-modifying medicines for psoriatic arthritis do dampen the immune response to some degree, so infection precautions and vaccine planning matter. I go through what to watch for, when to pause a medicine, and which vaccines to arrange before we start.
What monitoring will I need?
That depends on the medicine. Many require baseline screening, for example tuberculosis and hepatitis screening before biologics or targeted oral medicines, and blood tests at intervals to check blood counts, liver and kidney function. I set out the schedule for your particular medicine when we start.
Can I stop my medicine once I feel well?
Please do not stop, start or swap any of these medicines on your own. Feeling well often means the medicine is doing its job. If you want to reduce treatment, we can plan a careful, monitored step-down together rather than a sudden stop.
Are all of these medicines approved for every feature of psoriatic arthritis?
No, and this is important. Approvals and availability differ by medicine, by disease feature and by country. Some are licensed for skin psoriasis but not every joint or spinal indication. I will tell you where a particular option stands for your situation in Malaysia.
I am planning a pregnancy. Does that change things?
Yes, quite significantly. Some of these medicines are not suitable before or during pregnancy, and some need to be stopped well in advance. Please tell me early so we can plan a treatment that keeps your disease controlled and is appropriate for pregnancy.
Not sure which treatment fits you?
If you have psoriatic arthritis and want to talk through your options, or you are already on treatment and it does not feel like enough, message my clinic and we can review it together.
