The short answer
Avoid adding an active belladonna preparation to imipramine without prescriber review. Both can contribute anticholinergic effects, while the actual belladonna formulation determines exposure.
What this answer covers
Atropa belladonna products with active alkaloid exposure; whole plant, concentrated extracts and highly diluted products are not equivalent.
- Supplement or preparation
- Atropa belladonna
- Medication ingredient
- imipramine
Why the medicine warning matters
Imipramine has anticholinergic effects and its label calls for careful supervision with anticholinergic agents. Added effects may involve vision, urination, bowel function or mental clarity.
The plant itself can be toxic
A belladonna berry-ingestion case caused visual changes, dilated pupils, disorientation and agitation. This establishes an active-plant hazard, not the amount of risk from every product with belladonna on its label.
Confirm whether active alkaloids are present
Bring the exact product, dilution, plant part and dose for review. Do not assume raw plant, tincture and highly diluted products have the same exposure.
Recognize symptoms that need prompt care
New confusion, severe blurred vision, inability to urinate or significant abdominal distention needs urgent assessment, particularly after a new active belladonna product. Do not try to correct the problem by changing imipramine yourself.
Evidence and practical considerations
Side effects & toxicity
Conditional anticholinergic precaution is supported by exact imipramine warning and original plant-toxicity evidence; no quantified exact-pair risk.
- Exact scope
- Atropa belladonna products with active alkaloid exposure; whole plant, concentrated extracts and highly diluted products are not equivalent. with Exact oral imipramine hydrochloride tablets. RxNorm IN 5691/PIN 150816 hydrochloride; pamoate capsule is not assumed the same tested formulation. Desipramine metabolite evidence is distinguished from directly prescribed imipramine.
- Medication form and route
- oral
- Timing or duration
- Source-specific single-dose, repeated-dose and observational exposures distinguished.
What remains uncertain
- Plant poisoning report did not involve imipramine; ingredient name alone does not establish alkaloid dose.
Factors that may matter: preparation and plant part; clinical indication; dose; other medicines; baseline alertness.

Source 1: current product label
dailymed.nlm.nih.gov · Source check Sep 10, 2026
Population: People prescribed oral imipramine.
Exact label warns about anticholinergic and sympathomimetic co-use, alcohol-related CNS effects and MAOI combinations. It does not explicitly name tryptophan, St John’s wort or serotonin syndrome.
How this applies: RxNorm IN 5691/PIN 150816 hydrochloride; pamoate capsule is not assumed the same tested formulation. Desipramine metabolite evidence is distinguished from directly prescribed imipramine.
No universal supplement interval, event rate or preparation equivalence established. Original label distinguishes warnings from measured pair-specific results.
Source 2: original case report
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: One adult presenting after accidental berry ingestion.
Visual disturbance, dilated pupils, disorientation, loss of balance, agitation and anxiety were consistent with anticholinergic intoxication.
How this applies: Only the named drug, preparation, route and measured endpoints apply.
No imipramine and no supplement-extract assay; intrinsic plant poisoning does not quantify combination risk.
