Interaction Details
There were no interactions found between Sulfamethoxazole, Trimethoprim and Elderberry. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
Clinical studies involving elderberry suggest that the risk of significant drug interactions between it and other drugs is relatively low.
Elderberry has not been shown to affect any liver CYP enzymes to a clinically significant degree. This suggests that the potential for elderberry to interact with medications that are metabolized by these enzymes (e.g., CYP3A4, CYP2D6, etc...) is generally not a concern.
However, elderberry is purported to have immunostimulant activity and has been shown to increase the production of cytokines such as interleukin and tumor necrosis factor. These cytokines play a critical role in the immune response and can potentially counteract the effects of immunosuppressant drugs, which are used to treat autoimmune disorders and prevent rejection in transplant patients.
Additionally, drugs that affect some of these substances (e.g, Humira) could theoretically interact with elderberry, but this has not been seen in any human trials.
Bactrim, a combination of sulfamethoxazole and trimethoprim, is not known to be affected by elderberry and is generally considered safe to take with it.
