Interactions between your drugs
ampicillin typhoid vaccine, live
Applies to: ampicillin and typhoid vaccine, live
ADJUST DOSING INTERVAL: The use of live attenuated typhoid vaccine with antimalarials, sulfonamides, and/or antibiotics may result in a diminished immunologic response to the vaccine. Some antibiotics may be active against the vaccine strain of Salmonella typhi, thereby preventing a sufficient degree of multiplication to occur in order to induce a protective immune response.
MANAGEMENT: Live attenuated typhoid vaccine should not be administered for at least 3 days before or after treatment with antimalarials, sulfonamides, or antibiotics.

ADJUST DOSING INTERVAL: Certain penicillins may exhibit reduced gastrointestinal absorption in the presence of food. The therapeutic effect of the antimicrobial may be reduced.
MANAGEMENT: The interacting penicillin should be administered one hour before or two hours after meals. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.
