Uzara and Nebivolol Hydrochloride, Valsartan

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 Nebivolol Hydrochloride, Valsartan and Uzara 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 Nebivolol Hydrochloride, Valsartan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nebivolol Hydrochloride, Valsartan is filed under 7 classifications — including angiotensin receptor blockers (arbs), beta-blockers, cytochrome p450 2c9 (cyp2c9) substrates. Uzara has documented interactions with 6 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and macrolide antibiotics (moderate) — and none of Nebivolol Hydrochloride, Valsartan’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 Uzara Itself Has Been Linked To

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

From our pharmacist’s overview on the Nebivolol Hydrochloride, Valsartan page

“Nebivolol with valsartan (Byvalson) packs two blood pressure medicines into one pill, and I would treat this list with genuine care, especially its handful of serious entries.

About Uzara

What is Uzara?

  • Diarrhea
  • Stomach cramps
  • Menstrual cramps (dysmenorrhea)
  • Headaches
  • Digestive upset

Uzara is a traditional African root remedy used mainly for diarrhea and stomach cramps. Because it contains cardiac glycosides that can affect the heart, it should be used cautiously and for short periods only. Talk to a pharmacist or doctor before using it, especially if you have heart problems, are pregnant, or take heart medications.

Xysmalobium undulatum · Apocynaceae · Dried root · Liquid extract, tincture, tablets, drops

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

Uzara: dosing

There is no well-established standard dose for Uzara, and products vary in strength. The right amount depends on the specific preparation, such as drops, tincture, or tablets.The safest approach is to follow the directions on the product label and use it only for short periods. Do not exceed the recommended amount, since higher doses raise the risk of heart-related side effects.
