White Dead Nettle Flower and Posaconazole

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 Posaconazole and White Dead Nettle Flower 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 White Dead Nettle Flower at all — not against Posaconazole, 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.

From the ADVERSE REACTIONS section of the FDA label for Posaconazole. Read the label on DailyMed › Where a percentage is shown, it is the share of 15,719 voluntary FDA FAERS reports for Posaconazole that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. White Dead Nettle Flower’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no White Dead Nettle Flower side to compare — that is a limit of the record, not a statement that White Dead Nettle Flower has no side effects.

About White Dead Nettle Flower

What is White Dead Nettle Flower?

  • Menstrual complaints
  • Mild digestive upset
  • Sore throat and coughs
  • Mild urinary or vaginal discomfort
  • Minor skin irritation (topical)

White dead nettle flower is a traditional European herbal remedy used for menstrual, digestive, and minor throat or skin complaints. High-quality human studies are largely lacking, so its benefits are not well proven. It is generally considered mild, but should be avoided in pregnancy and breastfeeding due to limited safety data, and you should check with a pharmacist before use.

Lamium album · Lamiaceae · Flowers (and sometimes the flowering tops) · Tea, tincture, dried herb, capsules, topical preparations

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

White Dead Nettle Flower: dosing

There is no officially established or standardized dose for white dead nettle flower. Traditional use typically involves a tea made from the dried flowers, but the amount varies between sources and products.Because a reliable, well-studied dose has not been set, the safest approach is to follow the directions on the product label.

About Posaconazole

What Is Posaconazole Used For?

Brand name: Noxafil

Posaconazole is used to treat invasive aspergillosis (a serious mold infection that can spread through the body) in adults and certain pediatric patients, depending on the formulation and weight. It is also used to treat oropharyngeal candidiasis (OPC) — a yeast infection of the mouth and throat, including cases that have not responded to itraconazole and/or fluconazole — and this use is specific to the oral suspension in patients aged 13 and older.

Posaconazole is also used for prophylaxis (prevention) of invasive Aspergillus and Candida infections in people at high risk because their immune systems are severely compromised — such as stem cell transplant recipients with graft-versus-host disease (GVHD) or people with blood cancers who have low white blood cell counts from chemotherapy. The specific formulation approved for prevention varies by age and weight.
