Drug & supplement interaction

Cannabinol (cbn) + Omadacycline (Oral)

Omadacycline (Oral) brand name: Nuzyra.

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 Cannabinol (cbn) and Omadacycline (Oral) 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.

Interaction report

Cannabinol (cbn) and Omadacycline (Oral)

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 Omadacycline (Oral) and Cannabinol (cbn) 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.

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.

Cannabinol (cbn) safety at a glance

Cannabinol (cbn) overall Use caution CBN is generally considered mild, but human safety data are limited and product quality varies.
Pregnancy Avoid Cannabis-derived compounds are not considered safe in pregnancy, so avoid CBN.
Breastfeeding Avoid Cannabinoids can pass into breast milk, so avoid CBN while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Omadacycline (Oral)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Omadacycline (Oral) is filed under 2 classifications — tetracycline antibiotics, oral drugs. Cannabinol (cbn) has documented interactions with 5 drug classes — the most serious being cytochrome p450 2b6 (cyp2b6) substrates (moderate), cytochrome p450 2c9 (cyp2c9) inhibitors (moderate) and cytochrome p450 2c9 (cyp2c9) substrates (moderate) — and none of Omadacycline (Oral)’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Cannabinol (cbn) and Omadacycline (Oral) May Share a Side Effect

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.

About Cannabinol (cbn)

What is Cannabinol (cbn)?

  • Sleep support
  • Relaxation
  • Pain or discomfort
  • Appetite-related concerns

Cannabinol (CBN) is a minor cannabinoid found in the cannabis plant, often marketed as a 'sleep' aid, but solid human research is very limited. Because it comes from cannabis and product quality varies widely, talk with your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

Cannabaceae · Aged cannabis flower and resin (where THC degrades into CBN) · Oils and tinctures, gummies, capsules, vape products, topicals

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

Cannabinol (cbn): dosing

There is no established, standardized dose for CBN. Research is too limited to recommend a specific milligram amount, and products vary widely in strength and quality.If you choose to try a CBN product, follow the directions on the label and start with the lowest amount.

About Omadacycline Injection

What Is Omadacycline Injection Used For?

Brand name: Nuzyra

Nuzyra (omadacycline) injection is used in adults to treat two types of serious bacterial infections: community-acquired bacterial pneumonia (CABP) — a lung infection picked up outside of a hospital — and acute bacterial skin and skin structure infections (ABSSSI), which include serious skin infections such as those caused by MRSA (methicillin-resistant Staphylococcus aureus).

Nuzyra works only against bacterial infections. It is not effective against viral illnesses like the flu or common cold. Your doctor will prescribe it only when a bacterial infection is confirmed or strongly suspected, to help prevent the growth of antibiotic-resistant bacteria.

Is it safe to take Cannabinol (cbn) with Omadacycline (Oral)?

Do Cannabinol (cbn) and Omadacycline (Oral) have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.

Interactions in our licensed database are recorded against drug classes. Omadacycline (Oral) is filed under 2 classifications, and Cannabinol (cbn) has documented interactions with 5 drug classes — none of Omadacycline (Oral)'s classifications are among them.

Does Cannabinol (cbn) interact with any other medications?
