How many hours should i wait to consume alcohol after take 200 mg of benzonatate?

No need to wait, as for mucinix -- which I think you also asked about. You can safely assume that almost any over-the-counter medication is safe to take with alcohol. So are antibiotics (a common misunderstanding). If in doubt, check with your doctor. And if all this reflects ongoing overuse of alcohol, address that problem with your physician as well. Good luck.
