Drug & supplement interaction

Hoodia + Sulfasalazine

Sulfasalazine brand names: SAS, Azulfidine EN-Tabs, Azulfidine.

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 Hoodia and Sulfasalazine 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

Hoodia and Sulfasalazine

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 Sulfasalazine and Hoodia 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.

Hoodia safety at a glance

Hoodia overall Use caution Limited safety data exist, and side effects and product quality concerns have been reported.
Pregnancy Avoid There is not enough safety information, so avoid use during pregnancy.
Breastfeeding Avoid There is not enough safety information, so avoid use 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 Sulfasalazine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sulfasalazine is filed under 3 classifications — including photosensitizing drugs, oral drugs. Hoodia has documented interactions with 4 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and beta-blockers (moderate) — and none of Sulfasalazine’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.

No Interaction Found — But Data Suggests Hoodia and Sulfasalazine 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.

  • Dizziness / Headache Additional detail

    Hoodia

    “Orally, hoodia has been reported to cause minor adverse effects including disturbances of skin sensation, headache, dizziness, giddiness, and nausea. There is also concern that hoodia may increase blood pressure and heart rate.”

Effects for Sulfasalazine come from the ADVERSE REACTIONS section of its FDA label; effects for Hoodia come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 76,994 voluntary FDA FAERS reports for Sulfasalazine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Sulfasalazine

This page covers Hoodia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sulfasalazine page lists 39 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bergamot (moderate).

By severity: 1 major · 28 moderate · 10 minor.

From our pharmacist’s overview on the Sulfasalazine page

“Activated charcoal is the single major-rated risk for sulfasalazine (Azulfidine), because charcoal can bind the drug in the gut and cut how much your body absorbs, weakening a medicine people rely on for rheumatoid arthritis or ulcerative colitis. That entry alone earns this list of 39 supplements and herbs a careful read.”

About Hoodia

What is Hoodia?

Hoodia
  • Appetite suppression
  • Weight loss
  • Reducing food cravings
  • Traditional use for hunger and thirst on long journeys

Hoodia is a succulent plant from southern Africa that is marketed as an appetite suppressant for weight loss, but solid human evidence that it actually works is lacking. The few quality studies done have not shown meaningful weight loss, and some products on the market may not even contain real hoodia. Talk with your pharmacist or doctor before trying it, and avoid it if you are pregnant or breastfeeding.

Hoodia gordonii · Apocynaceae · Stem (aerial parts) · Capsules, tablets, powders, liquid extracts, teas, chews

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

Hoodia: dosing

There is no established, well-studied dose for hoodia. Products vary widely in their strength, purity, and how they are made, and some may not contain genuine hoodia at all.If you choose to try a hoodia supplement, follow the directions on the product label and do not exceed the recommended amount.

About Sulfasalazine

What Is Sulfasalazine Used For?

Brand names: SAS, Azulfidine EN-Tabs, Azulfidine

Sulfasalazine tablets (Azulfidine and generic) treat mild to moderate ulcerative colitis and are used as an add-on therapy in severe ulcerative colitis. They also help keep ulcerative colitis in remission — reducing the frequency of flare-ups.

The delayed-release tablets (Azulfidine EN-tabs and generic delayed-release) have the additional approvals of treating rheumatoid arthritis in adults who haven't responded well enough to NSAIDs or salicylates, and polyarticular-course juvenile rheumatoid arthritis in children who also haven't responded adequately to those drugs.

Taking Hoodia and Sulfasalazine Together: Common Questions

Is it safe to take Hoodia with Sulfasalazine?
We do not list a known interaction between Hoodia and Sulfasalazine. 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 Hoodia and Sulfasalazine have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Hoodia and Sulfasalazine combination checked?
Interactions in our licensed database are recorded against drug classes. Sulfasalazine is filed under 3 classifications, and Hoodia has documented interactions with 4 drug classes — none of Sulfasalazine'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 Hoodia interact with any other medications?
Yes. Hoodia has 262 documented drug interactions in our database — Sulfasalazine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sulfasalazine interact with any supplements?
Yes. Sulfasalazine has documented interactions with 39 supplements in our database — Hoodia is not one of them. The Sulfasalazine interaction page linked on this page lists every one, ranked by severity.
