Drug & supplement interaction

Star Of Bethlehem + tipranavir

tipranavir brand name: Aptivus.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Star Of Bethlehem and tipranavir 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. Additionally, although there is no interaction, the label for tipranavir states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Star Of Bethlehem and tipranavir

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 tipranavir and Star Of Bethlehem 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.

How we checked

Why No Interaction Is Listed for tipranavir

Interactions in our licensed database are recorded against drug classes, not just single drug names. tipranavir is filed under 11 classifications — including protease inhibitors (pis), cytochrome p450 2c19 (cyp2c19) substrates, cytochrome p450 3a4 (cyp3a4) inducers. Star Of Bethlehem has documented interactions with 7 drug classes — the most serious being corticosteroids (moderate), digoxin (lanoxin) (moderate) and diuretic drugs (moderate) — and none of tipranavir’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.

What to actually watch for

No Interaction Found — But Data Suggests Star Of Bethlehem and tipranavir May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

How to take them

Some tipranavir Products Have a Food Rule — Star Of Bethlehem Should Not Break It

At least one FDA label for a product containing tipranavir says to take it with food. If you take Star Of Bethlehem on an empty stomach out of habit, keep them separate — and take tipranavir with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two tipranavir products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.2 ) APTIVUS taken with ritonavir tablets must be taken with meals ( 2.1 ) APTIVUS capsules must be swallowed whole and must not be opened or chewed ( 2.1 ) Children should be assessed for their ability to swallow capsules before prescribing APTIVUS capsules.

From the Dosage and Administration section of the FDA label we read for tipranavir — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Star Of Bethlehem

What is Star Of Bethlehem?

  • Emotional shock and trauma
  • Grief and bereavement
  • Stress relief
  • Calming and comfort

Star of Bethlehem is a small flowering plant best known as one of the ingredients in Bach flower remedies, where it is used for emotional shock and grief. There is no solid scientific evidence that it treats any medical condition, and the raw plant and bulb are considered toxic, so it should not be eaten. If you choose to use a flower-essence product, treat it as a complement to—not a replacement for—proper medical care.

Ornithogalum umbellatum · Asparagaceae · Flowers (used in flower remedies); bulb in some traditional preparations · Flower essence (Bach flower remedy), liquid drops, often part of blends

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

Star Of Bethlehem: dosing

There is no established standard dose for Star of Bethlehem, and no medical dosing has been proven safe or effective. Flower-essence products are typically taken as a few drops by mouth or in water, following the directions on the label.If you choose to use a product, follow the manufacturer's instructions and do not exceed them. Never make your own preparation from the wild plant.

About Tipranavir

What Is Tipranavir Used For?

Brand name: Aptivus

Aptivus (tipranavir) is used to treat HIV-1 infection in adults and in pediatric patients weighing at least 36 kg (about 79 lbs). It is specifically for people who have already tried other HIV treatments and whose virus has become resistant to more than one protease inhibitor. It is always taken together with a low dose of ritonavir and with other HIV medications.

Aptivus is not recommended for people who have never taken HIV treatment before (treatment-naïve patients). Using tipranavir alongside additional active HIV drugs improves the chances of it working well.

Taking Star Of Bethlehem and tipranavir Together: Common Questions

Is it safe to take Star Of Bethlehem with tipranavir?
We do not list a known interaction between Star Of Bethlehem and tipranavir. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Star Of Bethlehem and tipranavir have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Star Of Bethlehem and tipranavir at the same time of day?
At least one FDA label for a product containing tipranavir says to take it with food. If you take Star Of Bethlehem on an empty stomach out of habit, keep them separate and take tipranavir with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two tipranavir products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Star Of Bethlehem and tipranavir combination checked?
Interactions in our licensed database are recorded against drug classes. tipranavir is filed under 11 classifications, and Star Of Bethlehem has documented interactions with 7 drug classes — none of tipranavir's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Star Of Bethlehem interact with any other medications?
Yes. Star Of Bethlehem has 156 documented drug interactions in our database — tipranavir is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does tipranavir interact with any supplements?
Yes. tipranavir has documented interactions with 212 supplements in our database — Star Of Bethlehem is not one of them. The tipranavir interaction page linked on this page lists every one, ranked by severity.
