Vomiting and medicine question - urgent

Hello,
After feeling awful since this afternoon, I just threw up 40-45 minutes after taking my evening dose of mino and Lyrica. I saw really jumbo, fluffy-looking pill forms in my vomit. I haven't taken my evening dose of omnicef or septra ds yet.
Should I still take the omnicef and septra? Do you think the Lyrica and mino were absorbed? This is the 2nd Wednesday out of 2 weeks of MWF pulsing treatment that I've thrown up. And I'm scheduled to take Flagyl tmw and Fri...
Thanks

Thank you so much, Heathersdad. I can't tell you how much I appreciate your guidance.

Opugirl, I really appreciate your help. I am looking up the packaging insert information and may even call the pharmacy about these specific drugs.

It is good to know that for you the vomiting issue was short-lived after introducing a new medicine. I really hope that the same will be true for me as well. I just ate dinner -- you know you're starving when you throw up twice and still want to eat -- and will take the omnicef and septra. Fingers crossed.

Thank you again.

Thanks, scooterscooter. I will definitely call them tmw. Will let you know what they say.
