Interaction report

Savin Tops and Technetium (99m Tc) Fanolesomab

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 Technetium (99m Tc) Fanolesomab and Savin Tops 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 Savin Tops at all — not against Technetium (99m Tc) Fanolesomab, 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.

About Savin Tops

What is Savin Tops?

  • Inducing menstruation
  • Attempting abortion (historical)
  • Skin warts and growths
  • Intestinal worms
  • Joint and muscle aches (topical)

Savin Tops comes from the savin juniper, a shrub whose oil is highly toxic and was historically misused to bring on menstruation or end pregnancy. It is considered dangerous and is not recommended for any use; serious poisonings and deaths have been reported. Do not take it internally.

Juniperus sabina · Cupressaceae · Young leafy branch tips (tops) and essential oil · Dried herb, essential oil, tinctures, and topical preparations (all rarely used today)

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

Savin Tops: dosing

There is no established or safe dose of Savin Tops. Because the plant is highly toxic and the harmful dose is very close to any traditionally used amount, no responsible dosing recommendation can be given.This herb is not recommended for self-treatment in any form.
