Interaction Details
There were no interactions found between Collagenase Clostridium Histolyticum-Aaes and 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.
Pharmacist Analysis
While there is no known interaction between valerian and the drug in question here, it does have potential interactions with other drugs that are important to be aware of.
For example, valerian may enhance the effects of central nervous system depressants, such as alcohol, benzodiazepines, and barbiturates. This means that combining valerian with these drugs can lead to excessive sedation and other side effects, such as dizziness and impaired coordination.
Similarly, if you take a drug that causes you to feel tired (e.g., Benadryl), valerian may enhance that effect.
Valerian may also interact with certain medications metabolized by the liver, such as statins and some antidepressants, as it can affect the liver enzymes that break down these drugs. For example, valerian may affect drugs metabolized via the CYP3A4 enzyme.
This can result in increased levels of these medications in the bloodstream, leading to potential side effects and toxicity.
We have hundreds of interactions listed for valerian that you can find in this interaction tool, but as always, if you are taking any prescription medications, it is important to talk to your healthcare provider before using valerian or any other supplements to ensure they are safe and appropriate for you.

Collagenase Clostridium Histolyticum-Aaes Overview
-
Collagenase Clostridium histolyticum injection (Xiaflex) is used to treat Dupuytren's contracture (a painless thickening and tightening of tissue [cord] beneath the skin in the palm of the hand, which may make it difficult to straighten one or more fingers) when a cord of tissue can be felt upon examination. Collagenase Clostridium histolyticum injection (Xiaflex) is also used to treat Peyronie's disease (a thickening of tissue [plaque] inside the penis that causes the penis to curve). Collagenase Clostridium histolyticum injection (QWO) is also used to treat cellulite (fat deposit beneath the skin) in the buttocks of adult women. Collagenase Clostridium histolyticum injection is in a class of medications called enzymes. In people with Dupuytren's contracture, it works by helping to break down the cord of thickened tissue and allows the finger(s) to be straightened. In people with Peyronie's disease, it works by helping to break down the plaque of thickened tissue and allows the penis to be straightened. In women with cellulite, it works by releasing fibrous bands, redistributing fat cells, and stimulating the growth of new collagen.
