Winter Cherry and Codeine Phosphate

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 Codeine Phosphate 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 Codeine Phosphate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Codeine Phosphate is filed under 6 classifications — including narcotic drugs, cytochrome p450 2d6 (cyp2d6) substrates, cns depressants. 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 Codeine Phosphate’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.

What Codeine Phosphate’s Own FDA Label Lists

This is not an interaction — none of it involves Winter Cherry. These are the most notable effects listed in the ADVERSE REACTIONS section of Codeine Phosphate’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Dependence or withdrawal symptoms Worth acting on
  • Serotonin syndrome Worth acting on
  • Low blood sugar Worth acting on
  • Pancreatitis Worth acting on
  • Fainting Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • Shortness of breath Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on

Showing the 10 most notable of 32 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Codeine Phosphate. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,086 voluntary FDA FAERS reports for Codeine Phosphate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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.

See Every Supplement That Interacts With Codeine Phosphate

This page covers Winter Cherry only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Codeine Phosphate page lists 144 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 7 major · 114 moderate · 23 minor.

From our pharmacist’s overview on the Codeine Phosphate page

“Codeine phosphate is an opioid painkiller and cough suppressant that slows breathing along with brain activity, and the wrong supplement can push that effect into dangerous territory. Seven of the 144 documented ingredients rate major, and nearly all of that serious risk comes from things that deepen sedation.”

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 Codeine

What Is Codeine Used For?

Brand name: Codeine

Codeine Sulfate tablets are used to manage mild to moderate pain in adults when non-opioid pain treatments have not worked or are not tolerated. It is only appropriate when an opioid is truly needed.

Because of the serious risks of addiction, misuse, overdose, and death, codeine is reserved for patients whose pain cannot be managed adequately with other options. It is not a first-choice pain reliever.

Most-Reported Side Effects for Codeine Phosphate

From FAERS, the FDA’s public side-effect reporting system (6,086 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dependence 3,533 reports
Overdose 730 reports
Back pain 471 reports
Back injury 240 reports
Arthralgia 173 reports
