MMR Drug Interactions

MMR Drug Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when MMR is combined with any of the drugs listed above.
Immune Globulins or Blood Products
Immune globulins or blood products may decrease the effectiveness of live vaccines such as MMR. Vaccination with MMR should be postponed for three months or more after a dose of immune globulin or after receiving a blood product.
If you are taking an immunosuppressant, you may not receive the full benefit of MMR. More importantly, with live vaccines such as MMR, people taking immunosuppressants may be at a higher risk of actually developing the infection (usually a mild form) from the vaccine.
In many situations, MMR may not be recommended for people taking immunosuppressants. Your healthcare provider will evaluate your individual situation before making a recommendation.
Tuberculin Skin Tests
Live vaccines like MMR may interfere with the accuracy of tuberculin skin tests, which are used to screen for tuberculosis. This interaction could increase the risk of false negatives. As a result, you should wait at least four weeks after getting the MMR vaccine before having a tuberculin skin test.

Final Thoughts
