Drug & supplement interaction

Cannabidiol (cbd) + Aminolaevulinic Acid

Aminolaevulinic Acid brand name: Levulan.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Cannabidiol (cbd) and Aminolaevulinic Acid 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

Cannabidiol (cbd) and Aminolaevulinic Acid

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 Aminolaevulinic Acid and Cannabidiol (cbd) 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.

How we checked

Why No Interaction Is Listed for Aminolaevulinic Acid

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aminolaevulinic Acid is filed under a single classification — topical drugs. Cannabidiol (cbd) has documented interactions with 37 drug classes — the most serious being brivaracetam (briviact) (moderate), caffeine (moderate) and carbamazepine (tegretol) (moderate) — and none of Aminolaevulinic Acid’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.

Keep it in perspective

Cannabidiol (cbd) Does Interact With Other Medications

No Interaction Found — But Data Suggests Cannabidiol (cbd) and Aminolaevulinic Acid 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.

Itching Additional detail
Cannabidiol (cbd)
“Orally, cannabidiol might cause rare skin reactions. In a clinical study in healthy adults, 2 cases of skin reactions, one severe and one mild, were reported. These and 2 additional cases were reported in a follow-up publication specific to cannabidiol-induced skin rash. The rash occurred in 4 female patients after taking oral cannabidiol 300 mg daily for up to 9 days.”

Aminolaevulinic Acid

Listed in the ADVERSE REACTIONS section of the FDA label for Aminolaevulinic Acid. Read the label on DailyMed ›

Reported for Cannabidiol (cbd) but not commonly for Aminolaevulinic Acid: liver problems, low blood pressure, dependence or withdrawal symptoms and reduced appetite.

Effects for Aminolaevulinic Acid come from the ADVERSE REACTIONS section of its FDA label; effects for Cannabidiol (cbd) come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Cannabidiol (cbd) in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

When used orally. The US Food and Drug Administration (FDA) strongly advises against the use of cannabidiol during pregnancy. Cannabidiol products might contain delta-9-tetrahydrocannabinol (THC) or other contaminants such as pesticides, heavy metals, bacteria, and fungus, which can be dangerous to the child. Also, animal research shows that high levels of cannabidiol can damage the reproductive system of male offspring.

Everything else you take

See Every Supplement That Interacts With Aminolaevulinic Acid

This page covers Cannabidiol (cbd) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aminolaevulinic Acid page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

By severity: 2 moderate · 1 minor.

From our pharmacist’s overview on the Aminolaevulinic Acid page

“If a dermatologist applies Levulan (aminolaevulinic acid) to your sun-damaged skin before a light treatment, the supplement picture is unusually narrow, because all three interactions on file involve products applied to the skin rather than anything swallowed. None is rated major.”

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

Anxiety and stress
Sleep problems
Chronic pain
Certain seizure disorders
Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.

Cannabis sativa · Cannabaceae · Flowers, leaves, and stalks of the hemp plant (extracted compound) · Oils and tinctures, capsules, gummies, topical creams, vape liquids, and a prescription solution

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

Cannabidiol (cbd): dosing

There is no single standard dose of CBD for general supplement use. The right amount can depend on the product, the reason for use, and the person. Because of this, it is best to follow the directions on the product label and start with a low amount.The only well-established dosing comes from the prescription CBD medicine used for seizures, which is carefully dosed by a doctor based on body weight. They can help you decide whether it is appropriate for you and review your other medicines for possible problems.

Taking Cannabidiol (cbd) and Aminolaevulinic Acid Together: Common Questions

Is it safe to take Cannabidiol (cbd) with Aminolaevulinic Acid?

We do not list a known interaction between Cannabidiol (cbd) and Aminolaevulinic Acid. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Cannabidiol (cbd) and Aminolaevulinic Acid 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. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

How was the Cannabidiol (cbd) and Aminolaevulinic Acid combination checked?

Interactions in our licensed database are recorded against drug classes. Aminolaevulinic Acid is filed under 1 classification, and Cannabidiol (cbd) has documented interactions with 37 drug classes — none of Aminolaevulinic Acid's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Cannabidiol (cbd) interact with any other medications?

Yes. Cannabidiol (cbd) has 1,051 documented drug interactions in our database — Aminolaevulinic Acid is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
