Taking Meds Together

So I had a NASTY migraine earlier. I get them frequently so I already had Imitrex on hand. My Dr. had also given me a sample of Relpax today. I took the Relpax, nothing. Took a 100mg Imitrex 4 hours later.

All I wanted was to take the edge off. Now I read that I shouldn't have taken them together, and am having a panic attack. Am I gonna be ok??
