The bottom line No known interaction

We found no known interaction between Quince and Dextroamphetamine 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.

Quince and Dextroamphetamine

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 Dextroamphetamine and Quince 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 Quince at all — not against Dextroamphetamine, 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.

Quince safety at a glance

Quince overall Use caution Quince as a food is generally well tolerated, but concentrated supplements are not well studied.
Pregnancy Use caution Quince as food is likely fine, but concentrated extracts or seed products lack safety data, so use caution.
Breastfeeding Use caution There is not enough reliable information on quince supplements during breastfeeding, so caution is advised.

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

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.

  • Serotonin syndrome Worth acting on
  • Severe muscle breakdown Worth acting on
  • A heart attack Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Dextroamphetamine. Read the label on DailyMed › Quince’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Quince side to compare — that is a limit of the record, not a statement that Quince has no side effects.

See Every Supplement That Interacts With Dextroamphetamine

This page covers Quince only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dextroamphetamine page lists 129 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Lithium (major), Peyote (major) and Rauvolfia Vomitoria (major).

By severity: 6 major · 100 moderate · 23 minor.

From our pharmacist’s overview on the Dextroamphetamine page

“Dextroamphetamine (Dexedrine) is a stimulant for ADHD and narcolepsy, and I read this list with genuine wariness. Six of the 129 ingredients rate major, most of them because other stimulants, ephedra being the clearest, pile extra heart rate and blood pressure on top of what the drug already produces.”

About Quince

What is Quince?

  • Digestive upset and diarrhea
  • Acid reflux and heartburn
  • Sore throat and cough
  • Skin soothing and wound care
  • Nausea

Quince is a tart, apple-like fruit traditionally used for digestive complaints, reflux, and soothing the throat and skin. Early research is interesting but limited, so quince should not replace proven treatments. Enjoying cooked quince in food is generally fine, but talk to a pharmacist or doctor before using concentrated supplements.

Cydonia oblonga · Rosaceae · Fruit, seeds, and leaves · Fresh fruit, jam or jelly, syrup, tea, dried seeds, capsules, extracts

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

Quince: dosing

There is no standardized or proven dose for quince supplements. The right amount depends on the product, the part of the plant used, and how it is prepared, which varies a lot between brands.If you choose to use a quince product, follow the directions on the label and do not exceed the suggested amount. Avoid eating raw or crushed seeds.

About Dextroamphetamine

What Is Dextroamphetamine Used For?

Brand name: Dexedrine

Dextroamphetamine treats two conditions: ADHD and narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness). It is available in multiple forms — tablets, extended-release capsules, oral solution, and a skin patch — and the approved age ranges vary by product.

Oral tablets (Zenzedi, generic) and oral solutions (Procentra, generic) are approved for ADHD in children as young as 3 years old and for narcolepsy. Extended-release capsules (Dexedrine, generic) are approved for ADHD in children ages 6 to 16 and for narcolepsy. Xelstrym, the transdermal patch, is approved only for ADHD — in adults and children ages 6 and older — and is not indicated for narcolepsy.
