Drug & supplement interaction

Pu-erh Tea + Daptomycin

Daptomycin brand names: Cubicin, Dapzura RT.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Pu-erh Tea and Daptomycin 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Pu-erh Tea and Daptomycin

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 Daptomycin and Pu-erh Tea 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.

How we checked

Why No Interaction Is Listed for Daptomycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Daptomycin is filed under a single classification — antibiotic drugs. Pu-erh Tea has documented interactions with 42 drug classes — the most serious being cimetidine (tagamet) (major), ephedrine (major) and adenosine (adenocard) (moderate) — and none of Daptomycin’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 to actually watch for

No Interaction Found — But Data Suggests Pu-erh Tea and Daptomycin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 3 of them are worth acting on rather than waiting out — marked below.

Reported for Pu-erh Tea but not commonly for Daptomycin: trouble concentrating, dependence or withdrawal symptoms, an irregular heartbeat and ringing in the ears.

Effects for Daptomycin come from the ADVERSE REACTIONS section of its FDA label; effects for Pu-erh Tea come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 9,174 voluntary FDA FAERS reports for Daptomycin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Pu-erh Tea in Pregnancy & Breastfeeding

Pregnancy Possibly Safe

When used orally in moderate amounts. Due to the caffeine content of pu-erh tea, intake should be closely monitored during pregnancy to ensure moderate consumption. Fetal blood concentrations of caffeine approximate maternal concentrations. Use of caffeine in pregnancy is controversial; however, moderate consumption has not been associated with clinically important adverse fetal effects. In some studies, consuming caffeine in amounts over 200 mg daily is associated with a significantly increased risk of miscarriage. This increased risk may be most likely to occur in those with genotypes that confer a slow rate of caffeine metabolism. According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, most healthy pregnant adults can safely consume caffeine doses up to 300 mg daily without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations. Advise keeping caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine found in about 3 cups of tea.

Pregnancy Possibly Unsafe

When used orally in large amounts. Caffeine from pu-erh tea crosses the placenta, producing fetal blood concentrations similar to maternal levels. Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies. Advise keeping caffeine consumption from all sources below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of tea. High intake of caffeine throughout pregnancy has resulted in symptoms of caffeine withdrawal in newborn infants. High doses of caffeine have also been associated with spontaneous abortion, premature delivery, and low birth weight. In a study that included 2 large cohorts of mother/infant pairs, the first cohort with a median maternal plasma caffeine level of 168.5 ng/mL (range 29.5-650.5 ng/mL) during pregnancy, suggests birth weights and lengths were lower in the 4th quartile of caffeine intake compared with the 1st. By age 7, heights and weights were lower by 1.5 cm and 1.1 kg respectively. In the second cohort of mother/infant pairs with higher maternal pregnancy plasma caffeine levels, median 625.5 ng/mL (range 86.2 to 1994.7 ng/mL), heights at age 8 were 2.2 cm lower, but there was no difference in weights.

Lactation Possibly Safe

When used orally in moderate amounts. Due to the caffeine content of pu-erh tea, caffeine intake should be closely monitored. Breast milk concentrations of caffeine are thought to be approximately 50% of maternal serum concentrations and caffeine peaks in milk approximately 1-2 hours after consumption. POSSIBLY UNSAFE...when used orally in large amounts. Consumption of pu-erh tea might cause irritability and increased bowel activity in nursing infants. Large doses or excessive intake of pu-erh tea should be avoided during lactation.

See Every Supplement That Interacts With Daptomycin

This page covers Pu-erh Tea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Daptomycin page lists 27 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Bacillus Coagulans (moderate), Bacillus Subtilis (moderate), Bifidobacterium Animalis Subsp. Lactis (moderate), Bifidobacterium Bifidum (moderate) and Bifidobacterium Breve (moderate).

By severity: 26 moderate · 1 minor.

From our pharmacist’s overview on the Daptomycin page

“Every one of the 27 supplement interactions on file for daptomycin (Cubicin, Dapzura RT) tells the same story. It is a potent IV antibiotic used for serious infections such as MRSA, and like any antibiotic it can kill the live organisms in probiotic supplements and fermented milk products, blunting their benefit rather than the drug's.”

About Pu-erh Tea

What is Pu-erh Tea?

Weight management
Cholesterol and heart health
Digestion after meals
Mental alertness
General antioxidant support

Pu-erh tea is a fermented, aged form of tea made from the same plant as green and black tea. It is enjoyed worldwide as a beverage and is sometimes promoted for weight loss, cholesterol, and digestion, but human evidence for these uses is limited. As a normal drink it is generally well tolerated, though it does contain caffeine.

Camellia sinensis · Theaceae · Leaves (fermented/aged) · Loose-leaf tea, compressed tea cakes, tea bags, capsules, extracts

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

Pu-erh Tea: dosing

There is no official or standardized dose of pu-erh tea for any health condition. Most people simply drink it as a brewed beverage, often one to several cups per day.For supplement capsules or extracts, follow the directions on the product label, since strength varies between products.

About Daptomycin Injection

What Is Daptomycin Injection Used For?

Brand names: Cubicin, Dapzura RT

Daptomycin injection is used to treat complicated skin and skin structure infections (cSSSI) caused by specific gram-positive bacteria — including MRSA (methicillin-resistant Staphylococcus aureus) — in adults and children ages 1 to 17. It is also used to treat Staphylococcus aureus bloodstream infections (bacteremia) in adults and children ages 1 to 17, including adult patients with right-sided infective endocarditis (a serious infection of the heart's inner lining).

Important limits: daptomycin injection is not approved for pneumonia or for left-sided infective endocarditis due to S. aureus. It is also not recommended for infants under 1 year of age due to potential risks to the muscular and nervous systems seen in animal studies.

Daptomycin Is Linked to Lower Levels of 7 Nutrients

Natural Medicines records Daptomycin as a medicine that can lower these. This is not an interaction with Pu-erh Tea — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:

Taking Pu-erh Tea and Daptomycin Together: Common Questions

Is it safe to take Pu-erh Tea with Daptomycin?

We do not list a known interaction between Pu-erh Tea and Daptomycin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Pu-erh Tea and Daptomycin have any of the same side effects?

Yes — our sources link each of them separately to 7 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

How was the Pu-erh Tea and Daptomycin combination checked?

Interactions in our licensed database are recorded against drug classes. Daptomycin is filed under 1 classification, and Pu-erh Tea has documented interactions with 42 drug classes — none of Daptomycin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Pu-erh Tea interact with any other medications?

Yes. Pu-erh Tea has 667 documented drug interactions in our database — Daptomycin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Does Daptomycin interact with any supplements?

Yes. Daptomycin has documented interactions with 27 supplements in our database — Pu-erh Tea is not one of them. The Daptomycin interaction page linked on this page lists every one, ranked by severity.
