The bottom line No known interaction

We found no known interaction between Tolu Balsam and Amantadine 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.

Tolu Balsam and Amantadine

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 Amantadine and Tolu Balsam 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 Tolu Balsam at all — not against Amantadine, 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.

Tolu Balsam safety at a glance

Tolu Balsam overall Use caution Generally used in small amounts in foods and cough products, but it can cause allergic reactions and lacks strong safety data.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety during breastfeeding is unknown, so avoid medicinal use.

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

What Amantadine’s Own FDA Label Lists

This is not an interaction — none of it involves Tolu Balsam. These are the most notable effects listed in the ADVERSE REACTIONS section of Amantadine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on mentioned in 5.9% of FDA reports for Amantadine
  • Hallucinations Worth acting on mentioned in 7.7% of FDA reports for Amantadine
  • Trouble swallowing Worth acting on
  • Fainting Worth acting on
  • Confusion Worth acting on
  • Low mood Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • Dry eyes
  • Vivid dreams or nightmares

Showing the 10 most notable of 26 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Amantadine. Read the label on DailyMed › Where a percentage is shown, it is the share of 20,186 voluntary FDA FAERS reports for Amantadine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Tolu Balsam’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Tolu Balsam side to compare — that is a limit of the record, not a statement that Tolu Balsam has no side effects.

About Tolu Balsam

What is Tolu Balsam?

  • Cough and sore throat
  • Chest congestion
  • Wound and skin care (topical)
  • Flavoring and fragrance
  • Mild expectorant

Tolu balsam is a fragrant resin from a South American tree that has long been used as a flavoring and as an ingredient in cough syrups and throat lozenges. Good-quality human studies are lacking, so its real effectiveness is uncertain, and it can cause allergic skin reactions in some people. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have allergies.

Myroxylon balsamum · Fabaceae · Resinous balsam (oleoresin) collected from the tree trunk · Syrups, cough lozenges, throat preparations, tinctures, and as a flavoring or fragrance ingredient

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

Tolu Balsam: dosing

There is no well-established standardized dose for tolu balsam. It is most often found as a minor ingredient in cough syrups, lozenges, and tinctures rather than taken on its own.If you use a product that contains tolu balsam, follow the directions on the label and do not exceed the recommended amount.

About Amantadine

What Is Amantadine Used For?

Brand names: Symmetrel, Gocovri, Osmolex ER

Gocovri (an extended-release amantadine capsule) has two specific approved uses: treating dyskinesia (uncontrolled, involuntary movements) in people with Parkinson's disease who are taking levodopa-based therapy, and as an add-on treatment to levodopa/carbidopa for people experiencing "off" episodes (periods when Parkinson's symptoms return or worsen).

Most-Reported Side Effects for Amantadine
