A member asked:

Started singulair (montelukast) yesterday. also got an injection of 10 mg of decadron due to sinus issues. today i'm having intermittent palpitations. is this more likely to be from steroid injection or singulair (montelukast)!

A doctor has provided 1 answer

Steroids: This is a side effect of steroid injections. Also may include things like flushing, nausea, etc. To be very fair, singulair (montelukast) can also cause difficulty breathing and heart palpitations. But, these are listed as severe, rare side effects, while the palpitations from steroid injections are much more common. Good luck!
