Drug & supplement interaction

Chia + Chlorzoxazone

Chlorzoxazone brand names: Parafon Forte DSC, Paraflex.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Chia and Chlorzoxazone 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.

Chia and Chlorzoxazone

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 Chlorzoxazone and Chia 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Chia at all — not against Chlorzoxazone, 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.

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.

Chia safety at a glance

Chia overall Generally safe Chia is widely eaten as food and is generally well tolerated in normal amounts.
Pregnancy Use caution Likely fine as a food, but there is little research on concentrated supplement amounts, so stick to food portions and ask your doctor.
Breastfeeding Use caution Food amounts are likely fine, but high supplement doses have not been well studied, so use caution.

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

No Interaction Found — But Data Suggests Chia and Chlorzoxazone May Share a Side Effect

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.

  • Dizziness reported in 7.3% of FDA reports for Chlorzoxazone Additional detail

    Chia

    “Orally, chia might cause anaphylaxis in sensitive individuals. A single case of IgE-mediated anaphylactic reaction has been reported for a patient who consumed chia seeds. Symptoms, including pruritus in the mouth, urticaria, facial angioedema, shortness of breath, and dizziness, developed a few days after consuming chia seeds. The reaction was attributed to sensitivity to proteins in chia seeds.”

    Chlorzoxazone

    Listed in the ADVERSE REACTIONS section of the FDA label for Chlorzoxazone, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Chia but not commonly for Chlorzoxazone: a severe allergic reaction, shortness of breath, diarrhea and bloating or gas.

Effects for Chlorzoxazone come from the ADVERSE REACTIONS section of its FDA label; effects for Chia come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,295 voluntary FDA FAERS reports for Chlorzoxazone 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.

About Chia

What is Chia?

  • Source of fiber and omega-3 fats
  • Digestive health and regularity
  • Heart health and cholesterol
  • Blood sugar support
  • Weight management

Chia seeds are a nutritious whole food rich in fiber, plant-based omega-3 fats (ALA), and protein. They are generally safe as part of a healthy diet, and may modestly help with regularity and fullness, but strong proof for treating specific health conditions is limited. Drink plenty of water with them and start with small amounts.

Salvia hispanica · Lamiaceae · Seeds · Whole seeds, ground seeds, chia gel, oil, capsules, flour, fortified foods

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

Chia: dosing

There is no official, standardized medicinal dose for chia. It is usually eaten as a food, often a tablespoon or two per day added to meals, but amounts vary from person to person.If you use a chia product or supplement, follow the directions on the label and increase your intake gradually. Always take chia with a generous amount of water or other liquid.

About Chlorzoxazone

What Is Chlorzoxazone Used For?

Brand names: Parafon Forte DSC, Paraflex

Chlorzoxazone tablets are used to relieve discomfort caused by acute, painful musculoskeletal conditions — things like muscle spasms and the pain that comes with them. It is meant to be used alongside rest, physical therapy, and other treatments, not as a stand-alone cure.

It is not intended for long-term muscle problems; it's most useful during a short-term flare of muscle pain and stiffness.

Most-Reported Side Effects for Chlorzoxazone

From FAERS, the FDA’s public side-effect reporting system (1,295 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 98 reports
Dizziness 95 reports
Fatigue 93 reports
Headache 76 reports
Anxiety 66 reports

Taking Chia and Chlorzoxazone Together: Common Questions

Is it safe to take Chia with Chlorzoxazone?
We do not list a known interaction between Chia and Chlorzoxazone. 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 Chia and Chlorzoxazone have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Does Chlorzoxazone interact with any supplements?
Yes. Chlorzoxazone has documented interactions with 26 supplements in our database — Chia is not one of them. The Chlorzoxazone interaction page linked on this page lists every one, ranked by severity.
