Uzara and Doxycycline Hyclate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

TETRACYCLINE ANTIBIOTICS

Why this applies to Doxycycline Hyclate

Doxycycline Hyclate falls under TETRACYCLINE ANTIBIOTICS — the group Uzara interacts with.

Theoretically, concomitant use may increase risk of cardiac glycoside toxicity.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the idea behind this one. Uzara root naturally contains cardiac glycosides, the same general kind of heart-acting compounds found in certain heart drugs. The theory is that pairing it with a tetracycline antibiotic like doxycycline could nudge up the level or effect of those glycosides in your body, raising the risk of glycoside-related heart toxicity.

I want to be honest about the strength of this, though. It's theoretical, based on pharmacology rather than real cases, so for most people taking a short doxycycline course for an infection or acne it's unlikely to cause trouble. Doxycycline's own common effects are things like nausea, sun sensitivity, and stomach upset, not heart problems. Still, if you have a heart condition or take heart medicine, please run the Uzara plan past your pharmacist or doctor first.

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.

About Doxycycline

What Is Doxycycline Used For?

Brand names: Acticlate, Acticlate Cap, Lymepak

Doxycycline belongs to the tetracycline family of antibiotics. It's prescribed for many types of bacterial infections, including respiratory tract infections, sexually transmitted infections (STIs), tick-borne illnesses like Rocky Mountain spotted fever, and eye infections. It's also used to help prevent malaria and, in some cases, as a helper treatment for severe acne.

In situations where penicillin-type antibiotics can't be used — due to allergy, for example — doxycycline can step in as an alternative. It should only be used for infections that are proven or strongly suspected to be caused by bacteria.
