Interaction Details
There were no interactions found between Famciclovir 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.

Famciclovir Overview
-
Famciclovir is used to treat herpes zoster (shingles; a rash that can occur in people who have had chickenpox in the past). It is also used to treat repeat outbreaks of herpes virus cold sores or fever blisters in people with a normal immune system. Famciclovir is used to treat repeat outbreaks and to prevent further outbreaks of genital herpes (a herpes virus infection that causes sores to form around the genitals and rectum from time to time) in people with a normal immune system. Famciclovir is also used to treat returning herpes simplex infections of the skin and mucus membranes (mouth, anus) in people with human immunodeficiency virus (HIV) infection. Famciclovir is in a class of medications called antivirals. It works by stopping the spread of the herpes virus in the body. Famciclovir does not cure herpes infections and may not stop the spread of herpes virus to other people. However, it may decrease the symptoms of pain, burning, tingling, tenderness, and itching; help sores to heal; and prevent new sores from forming.
