Interactions between your drugs


typhoid vaccine, live proguanil

Applies to: Vivotif Berna Vaccine (typhoid vaccine, live) and Malarone (atovaquone / proguanil)

Ask your doctor before using typhoid vaccine, live together with proguanil. Proguanil can decrease the effectiveness of typhoid vaccine, live. Medications containing proguanil should not be administered until at least 10 days after the last dose of typhoid vaccine, live. This vaccine works by exposing you to a small dose of the virus or a protein from the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body. It is important that you tell your healthcare provider about all other medications that you are using including vitamins and herbs. Do not stop using your medications without talking to your doctor first.
