Methotrexate is commonly prescribed as the first-line treatment for rheumatoid arthritis, a chronic condition that affects millions across the UK. This autoimmune disease leads to painful inflammation of the joints, significantly impacting daily life. While effective, Methotrexate carries potential side effects that users should monitor closely.
Understanding Common Side Effects
According to the NHS, Methotrexate can lead to various side effects. Common symptoms include nausea, loss of appetite, mouth sores, diarrhea, headaches, and hair loss. Moreover, the medication can affect blood cells and liver function, necessitating regular blood tests for monitoring. Patients may also experience increased sensitivity to sunlight, requiring the use of high-factor sunscreen with an SPF of 30 or above during treatment.
While serious side effects are infrequent, occurring in fewer than 1 in 10,000 patients, it is crucial to recognize when to seek immediate medical attention. The NHS advises contacting a healthcare provider or calling 111 if you experience any of the following symptoms:
– Yellowing of the skin or eyes, indicating possible liver issues.
– Persistent cough, chest pain, or difficulty breathing, which may suggest lung inflammation.
– Swelling in the hands, ankles, or feet, changes in urination, or an inability to urinate, potentially indicating kidney problems.
– Fever, muscle aches, or a sore throat, which could signal an infection.
– Symptoms like bleeding gums, blood in urine, vomiting blood, or unexplained bruising that may suggest a blood disorder.
Identifying Serious Reactions
In rare instances, patients may experience severe allergic reactions to Methotrexate. In such cases, the NHS recommends dialing 999 if any of the following symptoms occur:
– Sudden swelling of the lips, mouth, throat, or tongue.
– Difficulty breathing or rapid breathing.
– A sensation of tightness in the throat or difficulty swallowing.
– Changes in skin color, such as blue, grey, or pale lips, tongue, or skin.
– Severe confusion, dizziness, or drowsiness.
– Unresponsiveness in a child or someone who has fainted.
Patients may also develop a rash that is swollen, raised, itchy, blistered, or peeling, indicating a potentially serious allergic reaction requiring immediate hospital treatment.
Precautions and Interactions
Methotrexate is not suitable for everyone. The NHS emphasizes the importance of informing your doctor if you have a history of allergic reactions to Methotrexate or other medications. Additionally, those who are pregnant, nursing, or have severe liver or kidney disease should avoid this treatment. Other conditions like infections, mouth ulcers, or a history of stomach or duodenal ulcers also warrant caution.
It is equally essential to disclose any other medications being taken, as various drugs can affect Methotrexate’s efficacy. This includes non-steroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, diuretics, and medications for epilepsy or asthma, among others.
