Drug & supplement interaction

Bittersweet Nightshade + Citalopram

Citalopram brand name: Celexa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Bittersweet Nightshade and Citalopram 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.

Bittersweet Nightshade and Citalopram

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 Citalopram and Bittersweet Nightshade 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 Bittersweet Nightshade at all — not against Citalopram, 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.

No Interaction Found — But Data Suggests Bittersweet Nightshade and Citalopram May Share Several of the Same Side Effects

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. 2 of them are worth acting on rather than waiting out — marked below.

About Bittersweet Nightshade

What is Bittersweet Nightshade?

Bittersweet Nightshade
  • Skin conditions like eczema and warts
  • Inflammation and joint discomfort
  • Muscle spasms
  • Respiratory complaints
  • Mild fluid retention (traditional 'cleansing' use)

Bittersweet nightshade is a traditional herb with toxic compounds, especially in its berries, and there is very little reliable human evidence that it works for any health condition. Because it can cause serious poisoning, it is not recommended for self-treatment, and it should be avoided during pregnancy and breastfeeding.

Solanum dulcamara · Solanaceae · Stems (twigs), leaves, and sometimes berries · Dried stems, teas, tinctures, topical ointments or creams, homeopathic preparations

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

Bittersweet Nightshade: dosing

There is no established safe or standardized dose for bittersweet nightshade. Because the plant is toxic and the amount of active alkaloids can vary widely, it is not possible to give a reliable, safe amount to take by mouth.If you encounter a commercial product (such as a topical cream or a homeopathic remedy), follow the label exactly and do not exceed the recommended use. We do not recommend taking bittersweet nightshade internally for self-treatment.

Brand name: Celexa

Citalopram — available as tablets (including brand Celexa), oral solution, and capsules — is used to treat major depressive disorder (MDD) in adults.

Citalopram capsules are specifically indicated for adults with MDD but are not intended for starting or stopping treatment — another citalopram product must be used for dose titration. All forms are indicated for adults only; citalopram tablets are not approved for use in children.

Do Bittersweet Nightshade and Citalopram have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.
