HelloPharmacist Scorecard of Shiitake Alcohol Free by Hawaii Pharm
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: shiitake mushroom extract in dry form. Shiitake is a culinary mushroom used traditionally in Asian cuisine and has been studied for various potential health roles.
The liquid is made with glycerin and water as inactive ingredients that serve as the carrier base for the extract.
Does it work?
Couldn't assess
The evidence for shiitake mushroom's effectiveness is mixed and incomplete. For dental plaque, it's rated possibly ineffective.
For several conditions—including chemotherapy-induced anemia, atherosclerosis, breast cancer, and cancer in general—there isn't enough reliable evidence to say whether it works or doesn't. If you're considering this product for a specific health goal, talk with your doctor about what the current research actually supports.
How safe is it?
Well-documented data
Shiitake is generally well tolerated when you eat it cooked as food. The most common side effects from oral use are mild stomach upset: abdominal discomfort, bloating, diarrhea, nausea, and vomiting.
Rare but serious concerns include shiitake dermatitis (a skin rash with whiplash-like marks) from eating raw mushroom, and intestinal blockage from large unchewed pieces. People who handle fresh shiitake extensively can develop allergic reactions—contact dermatitis, asthma, and rarely, a lung condition from spore inhalation.
There isn't enough safety data on supplement doses to say whether concentrated shiitake supplements carry different or greater risks than food amounts.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use an immunosuppressant medication—shiitake may weaken its effect. Also double-check any drug metabolized by the liver enzyme CYP2D6, which includes certain antidepressants, blood pressure drugs, pain relievers, and heart rhythm medications; shiitake might lower their levels.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Shiitake mushroom extract may be worth considering if you're interested in traditional culinary mushroom nutrition, but the evidence for specific health claims is weak or absent. The main caution is if you take an immunosuppressant or a CYP2D6-metabolized medication—check with your doctor or pharmacist first.
And if you're pregnant, breastfeeding, or have a history of mushroom allergies or contact sensitivity, talk it over with your healthcare provider before starting.

Shiitake Alcohol Free by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Hawaii Pharm's Shiitake Alcohol Free contains shiitake mushroom extract, which does interact with medications in two important ways.
The most serious concern is with immunosuppressants—drugs that deliberately weaken your immune system after organ transplant or for certain autoimmune conditions. Shiitake may reduce how well these drugs work, which could be risky if your immune system becomes too active.
Read the full breakdown — every affected drug type, severity by severity
The second interaction involves a large group of common medications broken down by your liver enzyme called CYP2D6. In lab studies, shiitake extract appears to speed up this enzyme, potentially lowering blood levels of drugs it processes.
This hasn't been confirmed in humans yet, but it's a theoretical risk worth checking. Altogether, these interactions span 312 individual medications.
If you take an immunosuppressant or any drug metabolized by CYP2D6—including certain antidepressants, some blood pressure medications, pain relievers, and antiarrhythmics—run your exact medications through the interaction checker on this page before starting shiitake. Your doctor or pharmacist can tell you whether the risk applies to your specific regimen.
