Question 1

Can a patient on warfarin have a joint injection?

Accepted Answer

Usually yes, for a low-bleeding-risk peripheral injection, provided the international normalised ratio is recent and within the therapeutic range and local policy allows it. Stopping warfarin for such a procedure exposes the patient to thrombotic risk without meaningful benefit. A value above the range is a reason to defer and have it corrected rather than to proceed.

Question 2

How do direct oral anticoagulants differ in this decision?

Accepted Answer

There is no routine test equivalent to the international normalised ratio. Instead, check that the dose is right for the indication and renal function, adherence and the time of the last dose, interacting medicines, and any sign of overdose or active bleeding. The indication for anticoagulation remains the key context.

Question 3

Which procedures carry higher bleeding risk?

Accepted Answer

Risk depends on depth and compressibility rather than the name of the joint. Superficial compressible targets such as a subacromial injection, a small hand joint or a superficial bursa are low risk, and peripheral arthrocentesis is generally regarded as low risk too. Deep gluteal, iliopsoas and deep hip procedures carry more risk, and spinal or neuraxial procedures the most, following specialist protocols.

Question 4

Should aspirin or clopidogrel be stopped before an injection?

Accepted Answer

Generally no, for a peripheral joint or soft tissue injection: stopping them adds cardiovascular risk without meaningful benefit. Dual antiplatelet therapy, or treatment after a recent coronary stent, is never stopped without specialist advice. Technique reduces the risk further: the smallest suitable needle, few passes, a route avoiding visible vessels and firm direct pressure afterwards.
