Methotrexate and Botox

Having recently being diagnosed with RA I'm now taking weekly 15mg methotrexate injection so far I'm tolerating it well (so far only had 3 injections). It's early days so not yet feeling any relief to my painful symptoms.

Just wanting to know if it's safe to have Botox injections for brow lines/wrinkles around eyes whilst taking this medication. I've got an appt coming up and my practitioner says it's ok but I'd appreciate some comments from other RA sufferers.
