Manaca + Tenofovir Disoproxil Fumarate
Tenofovir Disoproxil Fumarate brand name: Viread.
We found no known interaction between Manaca and Tenofovir Disoproxil Fumarate 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.
Manaca and Tenofovir Disoproxil Fumarate
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 Tenofovir Disoproxil Fumarate and Manaca 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 Manaca at all — not against Tenofovir Disoproxil Fumarate, 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.

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Manaca is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Manaca reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified October 4, 2026. The Manaca and Tenofovir Disoproxil Fumarate records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Manaca
What is Manaca?
- Joint pain and arthritis
- Rheumatism
- Skin conditions
- As a diuretic
- Inflammation
Manaca (Brunfelsia uniflora) is a South American shrub traditionally used for arthritis, rheumatism, and skin problems. There is very little reliable human research to support these uses, and the plant belongs to the nightshade family and may be toxic, so caution is strongly advised. Talk to a pharmacist or doctor before using it.
Brunfelsia uniflora · Solanaceae · Roots and bark; sometimes leaves · Tincture, dried root, capsules, tea, homeopathic preparations
An interaction check asks whether these two react with each other — it does not ask whether Manaca is a good idea for someone in your situation. Here is what our Manaca record says about it on its own.
Manaca: dosing
There is no established or standardized dose for manaca. Because the plant may be toxic and has not been tested in proper human studies, safe dosing has not been determined.If you choose to use a product that contains manaca, follow the directions on the label and do not exceed them.

About Tenofovir disoproxil fumarate/Tenofovir alafenamide
What Is Tenofovir disoproxil fumarate/Tenofovir alafenamide Used For?
Brand name: Viread
-
Tenofovir disoproxil fumarate (DF) (Viread) is used along with other medications to treat HIV infection in adults and children 2 years of age and older weighing 22 pounds (10 kilograms) or more. Tenofovir DF is also used to treat chronic (long term) HBV in adults and children 2 years of age and older weighing 22 pounds (10 kilograms) or more. Tenofovir alafenamide (AF) (Vemlidy) is used to treat chronic (long term) HBV in adults and children 12 years of age and older who have stable liver disease. Tenofovir is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). It works by decreasing the amount of HIV and HBV in the blood. Although tenofovir will not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of transmitting the HIV virus to other people. Tenofovir will not cure hepatitis B and may not prevent complications of chronic hepatitis B such as cirrhosis of the liver or liver cancer. Tenofovir may not prevent the spread of hepatitis B to other people.
