Tai Chi + Promethazine
Promethazine brand name: Phenergan.
We found no known interaction between Tai Chi and Promethazine 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.
Tai Chi and Promethazine
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 Promethazine and Tai Chi in our sources. This does not guarantee that the combination is completely free of risk — research on Tai Chi alongside specific medications may be limited.
Worth understanding: our licensed dataset holds no drug-interaction record for Tai Chi at all — not against Promethazine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
Tai Chi is a practice rather than something you take. Ask your care team whether the type and intensity you plan to practice are appropriate for your health and treatment. 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.

Questions About Tai Chi or Promethazine
These are real questions from readers, answered by the pharmacists at HelloPharmacist — written by a person, not generated from a database. Each one covers Tai Chi or Promethazine, not necessarily both, but if one is close to what you were about to ask it will usually go further than a database entry can:
- Can Trazodone Cause A False-Positive For Amphetamines? ›
- Can You Take Benadryl With A Z-Pak (Azithromycin)? ›
- Taking Promethazine With Codeine With NyQuil ›
Not quite your question? Ask our pharmacists directly — it is free, there is no account required, and answers usually come back within 24 hours.
See Every Supplement That Interacts With Promethazine
This page covers Tai Chi only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Promethazine page lists 83 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Henbane (major), Scopolia (major), Alfalfa (moderate) and Angel's Trumpet (moderate).
By severity: 3 major · 57 moderate · 23 minor.
From our pharmacist’s overview on the Promethazine page
“Promethazine (Phenergan) is a phenothiazine antihistamine used for allergies, nausea, and motion sickness, and it is strongly anticholinergic on its own, causing dry mouth, blurred vision, drowsiness, and constipation. That is why the 83 supplements and herbs on this list deserve real attention, starting with the three rated major.”

Where Tai Chi and Promethazine Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.
#1,248 of 1,452 supplements looked up here in the last 7 days
#1,254 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Tai Chi is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Tai Chi reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Tai Chi and Promethazine records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Tai Chi
What is Tai Chi?
- Balance and fall prevention
- Stress and relaxation
- Joint pain and arthritis
- Heart and lung health
- Better sleep
- General fitness and flexibility
Tai Chi is a gentle, low-impact mind-body exercise that combines slow flowing movements, breathing, and focused attention. Research suggests it can improve balance, reduce falls, ease some chronic pain, and lower stress, and it is safe for most people. It is a practice, not a pill, so there are no doses or supplement risks to worry about.
Not applicable (mind-body movement practice) · Group classes, one-on-one instruction, video-guided sessions
An interaction check asks whether these two react with each other — it does not ask whether Tai Chi is a good idea for someone in your situation. Here is what our Tai Chi record says about it on its own.
Tai Chi: dosing
There is no "dose" for Tai Chi the way there is for a supplement. Many beginner programs involve sessions of about 30 to 60 minutes, done a few times a week, and benefits tend to grow with regular practice over weeks to months.The best approach is to follow your class or instructor's guidance and build up gradually at a pace that feels comfortable.

About Promethazine
What Is Promethazine Used For?
Brand name: Phenergan
Promethazine is used for a wide range of conditions. Tablets, oral solution, and rectal suppositories (brands including Phenergan, Promethegan, and Phenadoz) are approved for seasonal and perennial allergic rhinitis, vasomotor rhinitis, allergic conjunctivitis, hives (urticaria), angioedema, dermographism, and allergic reactions to blood or plasma. They are also used for motion sickness (both prevention and active treatment), nausea and vomiting related to anesthesia and surgery, sedation, and as a helper medication alongside pain relievers after surgery.
Promethazine hydrochloride injection (brands including Phenergan and Promethazine HCl injection) is used for many of the same purposes but is reserved for situations where oral treatment is not possible — including allergic emergencies as an adjunct to epinephrine, sedation during labor, and as an aid during certain surgical procedures such as bronchoscopy and eye surgery.
Most-Reported Side Effects for Promethazine
From FAERS, the FDA’s public side-effect reporting system (22,614 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
