The bottom line No known interaction

We found no known interaction between Acai and Cyclobenzaprine 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.

Acai and Cyclobenzaprine

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 Cyclobenzaprine and Acai 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.

Acai safety at a glance

Acai overall Use caution Acai is generally well tolerated as a food, but supplement quality and high-dose effects are not well studied.
Pregnancy Use caution Acai as a food is likely fine, but concentrated supplements have not been studied in pregnancy, so it is best to use caution.
Breastfeeding Use caution There is not enough safety information on acai supplements during breastfeeding, so caution is advised.

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

How we checked

Why No Interaction Is Listed for Cyclobenzaprine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cyclobenzaprine is filed under 8 classifications — including skeletal muscle relaxants, serotonergic drugs, serotonergic drugs. Acai has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Cyclobenzaprine’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.

About Acai

What is Acai?

Acai
  • Antioxidant support
  • Weight loss
  • Energy and vitality
  • Heart health
  • General wellness ('superfood')

Acai is a nutritious Amazonian berry rich in antioxidants and healthy fats, and it is fine to enjoy as a food. However, strong human evidence is lacking for the bold health claims often attached to acai supplements, including weight loss and disease prevention.

Euterpe oleracea · Arecaceae · Fruit (berry) and its pulp · Juice, frozen pulp, smoothie packs, powder, capsules, tablets

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

Acai: dosing

There is no officially established or standardized dose for acai. Amounts used in studies and products vary widely depending on the form (juice, pulp, powder, or capsule).The best approach is to follow the directions on the product label and not exceed the recommended amount.

From our Acai monograph — the full record covers uses, side effects and every documented interaction.

About Cyclobenzaprine

What Is Cyclobenzaprine Used For?

Brand names: Cyclobenzaprine, Flexeril, Cycloprine

Cyclobenzaprine tablets and extended-release capsules are used alongside rest and physical therapy to relieve muscle spasm caused by acute, painful musculoskeletal conditions — easing pain, tenderness, and limited movement. This use is intended for short-term treatment only (up to 2–3 weeks).

Tonmya, the sublingual (under-the-tongue) form of cyclobenzaprine, is separately indicated for the treatment of fibromyalgia in adults. It is not the same as the oral tablet or capsule formulations.
