See General under Precautions, regarding the administration of immune globulins, salicylates, and transfusions.
Drug Interactions, Use with Other Vaccines: Results from clinical studies indicate that refrigerator-stable VARIVAX can be administered concomitantly with M-M-R II, diphtheria and tetanus toxoids and pertussis vaccine adsorbed and Haemophilus influenzae type b conjugate combined vaccine, or Haemophilus influenzae type b Conjugate (Meningococcal Protein Conjugate) and Hepatitis B (Recombinant) combined vaccine (see Pharmacology: Studies with Other Vaccines under Actions).
Limited data from an experimental product containing varicella vaccine suggest that refrigerator-stable VARIVAX can be administered concomitantly with DTaP and PedvaxHIB using separate sites and syringes (see Pharmacology: Studies with Other Vaccines under Actions). However, there are no data relating to simultaneous administration of refrigerator-stable VARIVAX with DTP or OPV.
