What side effect is commonly associated with medications used for rheumatoid arthritis?

The side effect of rashes and photosensitivity is commonly associated with medications used for rheumatoid arthritis, particularly those in the class of disease-modifying antirheumatic drugs (DMARDs) and biologics. These medications can affect the skin and its response to sunlight, leading to conditions like rashes, which may appear as red, inflamed skin or lesions, and increased sensitivity to sunlight, resulting in easier sunburns or skin reactions when exposed to UV light.

These side effects are significant for patients, as they can impact quality of life and necessitate precautions when spending time outdoors or using certain skincare products that may exacerbate skin reactions. Recognizing these side effects is essential for both patients and healthcare providers to manage and mitigate risks associated with treatment.

In contrast, while aching joints is a symptom of rheumatoid arthritis itself, it is not a direct side effect of the medications used to treat the condition. Weight gain can occur due to various reasons, including lifestyle factors or medication side effects, but is less commonly directly associated with rheumatoid arthritis treatments. Excessive thirst is usually not a typical side effect of these medications.
