Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Temsirolimus may impair the antibody response to inactivated rabies vaccine. This is important for post-exposure treatment, where inadequate immunity could be fatal.

What this interaction means in plain words

Rabies vaccine and Temsirolimus can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

mTOR inhibition suppresses lymphocyte responses and so reduces vaccine immunogenicity.

What to do

Never withhold post-exposure prophylaxis because of temsirolimus; give immune globulin as indicated and check rabies neutralizing antibody titers afterward.

What to ask your pharmacist

  • Should I take them at different times of day?
  • Does the dose of either medicine need to change?
  • Is there anything I should avoid, such as alcohol or certain foods, while on both?
