Interaction Details
There were no interactions found between Hydroxychloroquine and Red-spur Valerian. 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.
Red-spur Valerian Overview
Red spur valerian (Centranthus ruber) is a perennial plant native to the Mediterranean region. It has pink or red flowers that bloom in the summer and can reach a height of up to 3 feet. It is also known as "Jupiter's beard" and "Devil's beard." In traditional medicine, red spur valerian has been used as a sedative and to promote sleep, as well as to treat digestive issues, and headaches. It should not be confused with a more commonly used herb, valerian (Valeriana officinalis). Red spur valerian and valerian are two different plants. While both are used in traditional medicine, they have different characteristics and uses.
Hydroxychloroquine Overview
-
Hydroxychloroquine is used to prevent and treat acute attacks of malaria in adults and children weighing more than 31 kg (68 lbs). It is also used to treat discoid lupus erythematosus (DLE; a chronic inflammatory condition of the skin) or systemic lupus erythematosus (SLE or lupus; an autoimmune disease in which the immune system attacks healthy parts of the body such as joints, skin, blood vessels, and organs) and rheumatoid arthritis. Hydroxychloroquine is in a class of drugs called antimalarials and is also an antirheumatic drug. It works by killing the organisms that cause malaria. Hydroxychloroquine may work to treat rheumatoid arthritis and systemic lupus erythematosus by decreasing the activity of the immune system.
