Myrcia + Voxelotor
Voxelotor brand name: Oxbryta.
We found no known interaction between Myrcia and Voxelotor 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.
Myrcia and Voxelotor
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 Voxelotor and Myrcia 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.
Myrcia safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Voxelotor
Interactions in our licensed database are recorded against drug classes, not just single drug names. Voxelotor is filed under 3 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Myrcia has documented interactions with 1 drug class — the most serious being levothyroxine (synthroid, others) (moderate) — and none of Voxelotor’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.

From our pharmacist’s overview on the Voxelotor page
“Anyone taking voxelotor (Oxbryta) for sickle cell disease should treat this list with real care, because the pattern behind it is unusually consistent. Almost every entry works through CYP3A4, the same liver enzyme that clears voxelotor, so these ingredients can push the drug's blood level higher or pull it lower, either adding side ef…”

About Myrcia
What is Myrcia?
- Blood sugar support
- Digestive upset and diarrhea
- Mild urinary complaints
- Astringent for the gut
- Traditional 'pedra-hume-caa' folk remedy
Myrcia is a group of tropical shrubs and trees in the myrtle family, used in South American folk medicine—often as a tea—mainly for blood sugar and digestive complaints. Human evidence is very limited, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you have diabetes or take other medicines.
Myrtaceae · Leaves (and sometimes bark) · Tea, dried leaf, capsules, liquid extracts
An interaction check asks whether these two react with each other — it does not ask whether Myrcia is a good idea for someone in your situation. Here is what our Myrcia record says about it on its own.
Myrcia: dosing
There is no established standardized dose for Myrcia. Traditional use is usually as a tea made from the dried leaves, but amounts vary widely and are not backed by clinical research.If you choose to try a commercial product, follow the directions on the label and do not exceed them.

About Voxelotor
What Is Voxelotor Used For?
Brand name: Oxbryta
Oxbryta (voxelotor) is approved to treat sickle cell disease (SCD) in adults and in children as young as 4 years old. It works by targeting the underlying problem in sickle cell disease — the abnormal hemoglobin that causes red blood cells to take on a rigid, sickle shape.
This approval was granted under the FDA's accelerated approval pathway, based on the drug's ability to raise hemoglobin levels. Continued approval may depend on results from confirmatory clinical trials showing broader clinical benefit.
Most-Reported Side Effects for Voxelotor
From FAERS, the FDA’s public side-effect reporting system (22,300 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
