It depends...: ...on how soon you vomit after each dose. Within 30 minutes, treatment may not work. After a half hour, usually enough antibiotic is retained or has been absorbed to still be effective. If both doxycycline and metronidazole, don't take them together and take both with food. Avoid alcohol. Also, azithromycin 1 dose can replace doxycycline. Discuss all this with the doctor or clinic treating you.
