Methotrexate is a commonly prescribed
disease-modifying anti-rheumatic drug (DMARD) used to treat
arthritis, psoriasis, and certain autoimmune conditions. It works as an
immunosuppressant, reducing the activity of the immune system to
control inflammation and prevent joint damage.Recently, the
NHS issued a warning emphasizing that patients on methotrexate should
not ignore certain symptoms, as they may indicate serious side effects requiring urgent medical attention.
How Methotrexate Works· Methotrexate
slows down the overactive immune system, which is responsible for joint inflammation in conditions like
rheumatoid arthritis.· By suppressing immune activity, it
reduces pain, swelling, and progression of joint damage.
Potential Side Effects and RisksWhile methotrexate is effective, it can also
cause side effects, some of which can be serious:1.
Gastrointestinal Symptomso Nausea, vomiting, or mouth ulcers may occur.o Severe or persistent vomiting requires medical evaluation.2.
Liver Toxicityo Methotrexate can affect
liver function, leading to elevated liver enzymes.o Symptoms like
yellowing of the skin/eyes, dark urine, or abdominal pain should be reported immediately.3.
Blood Disorderso Can reduce
white blood cells, red blood cells, or platelets, increasing infection risk and causing fatigue or unusual bruising.o Symptoms such as
persistent fever, unusual bleeding, or severe tiredness require urgent attention.4.
Lung Issueso Rarely, methotrexate can cause
lung inflammation, resulting in
shortness of breath, persistent cough, or chest pain.5.
Infectionso As an immunosuppressant, methotrexate
increases susceptibility to infections.o Patients should seek medical care if they develop
high fever, chills, or unusual infections.
NHS Advice: When to Seek Urgent Help· Call
999 or go to A&E if you experience:o Severe shortness of breath or chest paino High fever or signs of infectiono Unusual bleeding or bruisingo Yellowing of skin or eyes· Routine monitoring is essential:o
Blood tests for liver function, blood counts, and kidney functiono
Regular consultations with your doctor to adjust dosage if necessary
