The bottom line No known interaction

We found no known interaction between Winter Cherry and Allopurinol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Winter Cherry and Allopurinol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Allopurinol and Winter Cherry in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Winter Cherry safety at a glance

Winter Cherry overall Use caution Often well tolerated for short-term use, but quality of products and long-term safety are not well established.
Pregnancy Avoid Traditionally avoided in pregnancy because of possible effects on the uterus; do not use.
Breastfeeding Avoid Not enough safety information is available, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Allopurinol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Allopurinol is filed under 5 classifications — including antigout drugs, nephrotoxic drugs, hepatotoxic drugs. Winter Cherry has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and cytochrome p450 2e1 (cyp2e1) substrates (moderate) — and none of Allopurinol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Bleeding in the gut Worth acting on
  • A slow heartbeat Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Allopurinol. Read the label on DailyMed › Winter Cherry’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Winter Cherry side to compare — that is a limit of the record, not a statement that Winter Cherry has no side effects.

From our pharmacist’s overview on the Allopurinol page

“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

About Winter Cherry

What is Winter Cherry?

  • Stress and anxiety
  • Fatigue and low energy
  • Sleep support
  • General vitality and tonic
  • Athletic performance

Winter Cherry is another name for ashwagandha (Withania somnifera), an herb long used in Ayurvedic medicine, most often for stress, sleep, and energy. Some small studies suggest it may help with stress and anxiety, but the evidence is still limited and not definitive. It is generally well tolerated short-term, but pregnant women should avoid it, and anyone with a health condition should check with a pharmacist or doctor first.

Withania somnifera · Solanaceae · Root, and sometimes leaves and berries · Capsules, tablets, powder (churna), root extract, tea, tinctures

An interaction check asks whether these two react with each other — it does not ask whether Winter Cherry is a good idea for someone in your situation. Here is what our Winter Cherry record says about it on its own.

Winter Cherry: dosing

There is no official standardized dose for Winter Cherry, and products vary widely in strength and how they are made (for example, different root extracts standardized to different amounts of withanolides).Because of this, the best advice is to follow the directions on the product label and not exceed the recommended amount. It is often used for a limited period rather than indefinitely. A pharmacist or doctor can help you choose a reputable product and decide whether it is appropriate for you.

About Allopurinol

What Is Allopurinol Used For?

Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric

Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.

For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.

Most-Reported Side Effects for Allopurinol

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 8,726 reports
Fatigue 8,284 reports
Dyspnea 7,956 reports
Nausea 7,333 reports
