Wild Cherry and Alfuzosin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Alfuzosin

Alfuzosin falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Wild Cherry interacts with.

In vitro research suggests that wild cherry can inhibit cytochrome P450 3A4 (CYP3A4) enzymes. Theoretically, wild cherry might increase levels of drugs metabolized by CYP3A4. However, so far, this interaction has not been reported in humans.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for alfuzosin (Uroxatral): your liver uses an enzyme called CYP3A4 to clear it out of your system. Lab studies hint that wild cherry might slow that enzyme down a bit. If it did, alfuzosin could build up a little more than usual, which might nudge its effects up too.

With alfuzosin, the side effects to watch for are dizziness, lightheadedness, or feeling faint, especially when you stand up quickly, since it relaxes blood vessels along with the bladder muscles. That said, this is only seen in a test tube so far, never in real people, so I wouldn't lose sleep over an occasional cough lozenge. If you plan to use wild cherry regularly or in concentrated form, just run it by your pharmacist first.

From our pharmacist’s overview on the Alfuzosin page

“Alfuzosin (Uroxatral) relaxes muscle around the prostate to ease urine flow, and the body clears it almost entirely through one liver enzyme, CYP3A4. That dependence is why this list deserves genuine care rather than a quick skim.”

About Wild Cherry

What is Wild Cherry?

Wild Cherry
  • Cough
  • Bronchitis and respiratory irritation
  • Sore throat
  • Digestive upset and diarrhea
  • Flavoring agent

Wild cherry bark is a traditional cough remedy found in many old-fashioned cough syrups and lozenges, but there is little modern scientific evidence proving it works. The bark, leaves, and seeds naturally contain cyanide-producing compounds, so it should be used only in properly prepared products and avoided in large amounts. Talk with a pharmacist or doctor before using it, especially during pregnancy or for children.

About Alfuzosin

What Is Alfuzosin Used For?

Brand name: Uroxatral

Alfuzosin is used to treat the signs and symptoms of benign prostatic hyperplasia (BPH) — a non-cancerous enlargement of the prostate gland that can make urination difficult. It helps relax the muscles in the prostate and bladder neck so urine can flow more easily.

It is not approved to treat high blood pressure, and it is not for use in children or women.
