Drug & supplement interaction

Suma + Cefadroxil

Cefadroxil brand names: Duricef, Ultracef, Cef-Tab.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Suma and Cefadroxil 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.

Suma and Cefadroxil

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 Cefadroxil and Suma 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 Suma at all — not against Cefadroxil, 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.

Suma safety at a glance

Suma overall Use caution Generally used in foods and supplements, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.

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

What to actually watch for

What Suma Itself Has Been Linked To

This is not an interaction — nothing below involves Cefadroxil. It is the side-effect record for Suma on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Suma, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “Orally, suma seems to be well tolerated (12). No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted. When inhaled, powdered suma root can cause occupational asthma.”

Everything above comes from the Natural Medicines adverse-effect record for Suma — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Cefadroxil’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Cefadroxil column appears here.

Everything else you take

See Every Supplement That Interacts With Cefadroxil

This page covers Suma only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefadroxil page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefadroxil page

“Cefadroxil, a cephalosporin antibiotic usually taken as a short course for skin, throat, or urinary infections, has a supplement list that deserves genuine care, not a quick skim. Three of the 60 ingredients on file rate major.”

About Suma

What is Suma?

  • General energy and vitality
  • Adaptogen for stress
  • Sexual health and libido
  • Athletic performance
  • Immune support
  • Hormonal balance

Suma is a South American root often marketed as a 'Brazilian ginseng' and used as an adaptogen for energy, stamina, and stress. Human evidence is very limited, and most claims come from traditional use and lab or animal studies. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a hormone-sensitive condition.

Pfaffia paniculata · Amaranthaceae · Root · Capsules, powder, tablets, tincture, tea

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

Suma: dosing

There is no well-established standardized dose for Suma. Studies are too limited to recommend a specific amount, and product strengths vary widely.If you choose to use it, follow the dosing directions on the product label and do not exceed them. A pharmacist can help you review a product and decide whether it is appropriate for you.Start low, watch for any reactions, and stop if you notice side effects.

About Cefadroxil

What Is Cefadroxil Used For?

Brand names: Duricef, Ultracef, Cef-Tab

Cefadroxil treats bacterial infections caused by susceptible (antibiotic-sensitive) germs. It is approved for urinary tract infections, skin and skin structure infections, and pharyngitis or tonsillitis caused by Group A strep (Streptococcus pyogenes).

It should only be used for infections proven or strongly suspected to be caused by bacteria that respond to it. Taking it for viruses (like a cold or flu) will not work and contributes to antibiotic resistance.
