Drug & supplement interaction

Honeysuckle + Caffeine (prescription drug)

Caffeine (prescription drug) brand names: Dextrophin, Caffeine.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Honeysuckle and Caffeine (prescription drug) 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 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.

Interaction report

Honeysuckle and Caffeine (prescription drug)

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 Caffeine (prescription drug) and Honeysuckle 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.

Honeysuckle safety at a glance

Honeysuckle overall Use caution Often used as a tea with few reported problems, but high-quality safety data in humans is limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Caffeine (prescription drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Caffeine (prescription drug) is filed under 7 classifications — including methylxanthines, stimulant drugs, cytochrome p450 1a2 (cyp1a2) substrates. Honeysuckle has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Caffeine (prescription drug)’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.

No Interaction Found — But Data Suggests Honeysuckle and Caffeine (prescription drug) May Share a Side Effect

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.

  • A skin rash Additional detail

    Honeysuckle

    “Topically, applying honeysuckle to the skin has been associated with contact dermatitis in a case report. Orally, a case of biopsy-confirmed allergic drug eruption is reported in a young adult male after taking honeysuckle granules 30 grams over a 24-hour period. Symptoms resolved with discontinuation of honeysuckle and 2-weeks of antihistamine and glucocorticoid therapy.”

About Honeysuckle

What is Honeysuckle?

  • Colds and sore throat
  • Fever
  • Inflammation
  • Skin rashes and sores
  • Digestive upset

Honeysuckle, especially Japanese honeysuckle flower (Lonicera japonica), is a staple of traditional Chinese medicine used mainly for colds, sore throat, and inflammation. Modern human evidence for these uses is limited, so it should be seen as a traditional remedy rather than a proven treatment. It is generally well tolerated as a tea, but talk to your pharmacist or doctor before using it, especially if you are pregnant, nursing, or taking other medicines.

Lonicera japonica · Caprifoliaceae · Flowers (flower buds), and sometimes stems and leaves · Tea, dried flower buds, capsules, tinctures, topical preparations, and combination herbal formulas

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

Honeysuckle: dosing

There is no standard, well-established dose for honeysuckle. The right amount depends on the form (tea, capsule, tincture) and the specific product.The safest approach is to follow the directions on the product label and not take more than recommended.

About Caffeine

What Is Caffeine Used For?

Brand names: Dextrophin, Caffeine

Caffeine citrate injection and oral solution are used for the short-term treatment of apnea of prematurity. This means pauses in breathing in premature infants. The label lists the age range as infants between 28 weeks and a later gestational age, and that range is cut off in the text provided.

Over-the-counter caffeine tablets, such as Diurex and the Stay Awake products, are taken by mouth by adults and older children. Their labels point to fatigue and drowsiness. Diurex directions also mention taking it while symptoms persist.
