Interaction Details
There were no interactions found between hydrocortisone, clioquinol, pramoxine and Passion Flower. 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
Passionflower is not known to have many clinically significant drug interactions.
Nevertheless, it has been shown to have sedative effects, which can be additive when used in conjunction with sedative medications (e.g., Benadryl, benzodiazepines, opioids, etc...).
Therefore, we do list interactions between Passionflower and CNS (central nervous system) depressants or other drugs with strong sedative effects.
Additionally, certain constituents of Passionflower (such as apigenin and vitexin) may inhibit certain drug transports, specifically OATP2B1 and OATP1A2.
These are responsible for the uptake of certain drugs and other compounds into the body.
As Passionflower can inhibit these transports, it is possible that it might reduce the bioavailability of drugs that are substrates for these transporters but studies are far from conclusive on the matter.
There is no known drug interaction between Passionflower and the drug in question here, however.
As always, be sure to speak with your doctor before making any changes to your medication regimen.
- Dr. Brian Staiger, PharmDPassion Flower Overview
Passionflower (Passiflora incarnata) is a climbing vine with fragrant white and purple flowers that is native to the Americas.
It is purported to have a number of potential health benefits, including reducing anxiety and improving sleep. It is thought to work by increasing the levels of GABA (gamma-aminobutyric acid), a neurotransmitter in the brain that helps regulate mood and anxiety. Passionflower may also have mild sedative and muscle-relaxing effects and may be helpful in the treatment of muscle spasms and other muscle disorders.
Dietary supplements containing passionflower are generally standardized to contain no less than 1.5% of the flavanoid vitexin.
