Is it safe to use a SAD light therapy box while taking methotrexate?

While methotrexate can increase sun sensitivity for some people, especially those who've had past sunburns, SAD light therapy boxes typically emit different wavelengths than direct sunlight. However, it's important to take precautions.

Here are some things to consider:

* Methotrexate may cause skin irritation with light exposure in some people
* Limiting sun exposure and using sunscreen are generally recommended while on methotrexate
* SAD light boxes use specific light wavelengths that differ from UV rays

Since you've just started methotrexate, it's best to check with your rheumatologist before continuing with your light therapy box. They can advise you based on your specific situation and help you understand any potential risks.

In the meantime, you might want to start with shorter sessions and monitor how your skin responds. If you notice any unusual reactions, stop using it and contact your doctor right away.
