No Known Interaction
The bottom line No known interaction

We found no known interaction between Fireweed and Solriamfetol 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.

Fireweed and Solriamfetol

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 Solriamfetol and Fireweed 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 Fireweed at all — not against Solriamfetol, 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.

What Solriamfetol’s Own FDA Label Lists

This is not an interaction — none of it involves Fireweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Solriamfetol’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Chest pain Worth acting on
  • Shortness of breath Worth acting on
  • Hives Worth acting on
  • An allergic reaction Worth acting on
  • Trouble concentrating
  • Increased thirst
  • Weight loss
  • Mood changes or irritability
  • Anxiety or restlessness mentioned in 8.8% of FDA reports for Solriamfetol
  • Tremor or shakiness

Showing the 10 most notable of 25 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 Solriamfetol. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,694 voluntary FDA FAERS reports for Solriamfetol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Fireweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Fireweed side to compare — that is a limit of the record, not a statement that Fireweed has no side effects.

From our pharmacist’s overview on the Solriamfetol page

“Solriamfetol (Sunosi) promotes wakefulness in people with narcolepsy or sleep apnea by acting, in part, like a stimulant, and that is exactly why this page deserves careful attention rather than a quick skim. The great majority of the 61 interacting ingredients are stimulants themselves, so adding them can push blood pressure and heart…”

About Fireweed

What is Fireweed?

  • Prostate and urinary symptoms
  • Digestive upset and diarrhea
  • Skin irritation (topical)
  • Sore throat and mouth inflammation
  • General anti-inflammatory support

Fireweed is a wild flowering plant used traditionally as a tea and folk remedy, most often for prostate, urinary, digestive, and skin complaints. Human evidence is very limited, so its benefits are not well proven. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Epilobium angustifolium · Onagraceae · Aerial parts (leaves, flowers, and stems); a related species, Epilobium parviflorum, is often used for prostate concerns · Tea, dried herb, tincture, capsules, topical preparations

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

Fireweed: dosing

There is no well-established standardized dose for fireweed. Traditional use often involves a tea made from the dried leaves, while supplements come in capsules or tinctures with varying strengths.Because products differ so much, the safest approach is to follow the directions on the product label and not exceed the recommended amount. A pharmacist can help you review a specific product and decide whether it is appropriate for you.If you do not notice benefit, or you have ongoing symptoms, see a healthcare provider instead of increasing the dose on your own.

About Solriamfetol

What Is Solriamfetol Used For?

Brand name: Sunosi

Sunosi (solriamfetol) is approved to improve wakefulness in adults who experience excessive daytime sleepiness caused by narcolepsy or obstructive sleep apnea (OSA).

Important: Sunosi does not treat the airway obstruction that causes OSA. If you have OSA, you must continue your existing treatment — such as CPAP (a breathing machine worn at night) — throughout your time on Sunosi. Sunosi is not a replacement for those therapies.
