Interaction Details
There were no interactions found between Efavirenz, Lamivudine, Tenofovir Disoproxil Fumarate and Alder Buckthorn. 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.
Alder Buckthorn Overview
Alder buckthorn (Rhamnus frangula) is an invasive shrub native to Europe and North America. Its bark has been traditionally used in medicine due to its cathartic effects in the large intestine, attributed to its anthraglycoside content. It is generally used to help alleviate constipation. However, chronic use of alder buckthorn has been linked to gastrointestinal epithelial cell damage, pigmentation of the colonic mucosa (pseudomelanosis coli), and a potential risk of colorectal cancer. If used as a dietary supplement, the duration of use for alder buckthorn should be limited to no more than a few days altogether, due to its potential adverse effects on gastrointestinal health with prolonged use. In 1993, the FDA removed its Generally Recognized As Safe (GRAS) status due to insufficient safety data, particularly regarding prolonged use of its anthraquinone laxatives, reinforcing the need for caution in its medicinal use.
Efavirenz, Lamivudine, Tenofovir Disoproxil Fumarate Overview
-
The combination of efavirenz, lamivudine, and tenofovir is used to treat HIV in adults and children. Efavirenz is in a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Lamivudine and tenofovir are in a class of medications called nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs). They work by decreasing the amount of HIV in the body. Although efavirenz, lamivudine and tenofovir will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of getting or transmitting the HIV virus to other people.
