This review highlights methotrexate safety for rheumatologists, detailing benefits like subcutaneous administration and folic acid use. It addresses concerns regarding infection and pulmonary fibrosis, aiming to demystify this essential treatment.
Area of Science:
- Rheumatology
- Pharmacology
Background:
- Methotrexate is a cornerstone treatment in rheumatology.
- Non-specialists often have concerns regarding its safety profile.
Purpose of the Study:
- To review key safety aspects of methotrexate for non-specialist clinicians.
- To highlight practical strategies for optimizing methotrexate therapy and patient safety.
Main Methods:
- Review of existing literature and clinical guidelines on methotrexate use.
- Discussion of specific administration routes, adjunct therapies, and safety considerations.
Main Results:
- Methotrexate can be used safely with minimal risk of major infection or pulmonary fibrosis when managed appropriately.
- Subcutaneous administration offers benefits, and low-dose folic acid supplementation is recommended.
- Strategies like co-administration with hydroxychloroquine and temporary cessation for flu vaccination can enhance safety.
Conclusions:
- Methotrexate is a safe and effective treatment when practical management strategies are employed.
- Understanding these elements can demystify methotrexate use for a broader range of healthcare providers.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
