I took 30mg of cyclo, can I take a 5-500 hydrocodone with it? What would happen if I did?

Dicyclomine? If you mean taking Dicyclomine in combination with 5/500 hydrocodone, the common side effect is constipation and would watch out for it if these medications are in use for some time together. Both have the ability to slow down bowel function and this can lead to constipation.
