Final answer:
The information provided does not specify a particular drug required to be given with a booster medication, but it does reference the MMR vaccine for prevention, which may imply a need for booster doses.
Step-by-step explanation:
The drug that must be given with a booster medication is not specified in the reference provided. However, booster medications are often discussed in the context of vaccinations, where a booster dose of a vaccine is given after the initial series to 'boost' the immune response. In the provided reference, the MMR vaccine is mentioned for the prevention of certain viral infections, which implies that vaccines like MMR may require booster doses. Additionally, the reference includes information on antibiotics such as doxycycline, macrolides, beta-lactams, and antiviral medications like acyclovir, famcyclovir, valacyclovir, indicating that these may sometimes be used in a combination to manage infectious diseases. The dosage and route of administration are critical considerations in medical treatments to ensure therapeutic effectiveness while minimizing the risk of side effects.
