Varivax Drug Interactions
Varivax Drug Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when Varivax is combined with any of the drugs listed above.
Immune Globulins or Blood Products
Immune globulins and blood products (such as blood or plasma transfusions) decrease the effectiveness of live vaccines (like Varivax). Vaccination with Varivax should be postponed for five months after a dose of immune globulin.
Immune globulins should not be given for two months after a dose of Varivax, unless the potential benefits of the immune globulin outweigh the benefit of vaccination.
If you are taking an immunosuppressant, you may not receive the full benefit of Varivax. More importantly, with live vaccines (such as Varivax), people taking immunosuppressants may be at a higher risk of actually developing the infection (usually a mild form) from the vaccine. In many situations, Varivax may not be recommended for people taking immunosuppressants.
People should avoid taking any salicylates (including aspirin) for six weeks after receiving Varivax, due to the potential risk of Reye's syndrome (a potentially fatal condition). This interaction is theoretical, based on cases of Reye's syndrome seen when people with chickenpox took aspirin.
It is possible that not all drug interactions with Varivax were discussed in this article. Therefore, you should talk with your pharmacist or healthcare provider about any specific drug interactions that may apply to you.
