Arrach and Ciprofloxacin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Ciprofloxacin

Ciprofloxacin falls under PHOTOSENSITIZING DRUGS — the group Arrach interacts with.

Theoretically, concomitant use of arrach can increase risk of adverse effects, as unspecified Chenopodium species are associated with photosensitivity.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Cipro and arrach: ciprofloxacin can already make your skin more sensitive to sunlight, so you may sunburn faster than usual. Some goosefoot-family plants like arrach have been linked to that same kind of light sensitivity. Put the two together and, at least in theory, you could be a little more prone to a quick or stronger sunburn while on the antibiotic.

To be honest, this is a theoretical concern based on the plant's chemistry, not strong human studies, so I wouldn't lose sleep over it. Still, while you're on Cipro it's smart to use sunscreen, wear a hat, and limit long sun exposure. Cipro is not a prodrug here, so this doesn't change how well it fights your infection. Run any herbal use past your pharmacist first.

From our pharmacist’s overview on the Ciprofloxacin page

“A glass of apple or grapefruit juice can sharply cut how much ciprofloxacin (Cipro) your body absorbs, because these juices block a transporter the antibiotic needs to reach the bloodstream. That is one of eight major-rated risks among the 163 supplement and herbal ingredients on file, and I treat this list as a genuine warning rather…”

About Arrach

What is Arrach?

Arrach
  • Painful menstruation
  • Nervous complaints
  • Digestive upset
  • Wound care
  • Insect repellent

Arrach (Chenopodium vulvaria) is a strong-smelling European herb that has been used in traditional folk medicine, mainly for menstrual and nervous complaints. There is very little modern scientific evidence to show that it works or is safe, so it is not recommended, especially during pregnancy or breastfeeding. Talk to your pharmacist or doctor before using any herbal product.

About Ciprofloxacin

What Is Ciprofloxacin Used For?

Brand names: Cipro, Ciprobay, Cipro XR, Ciloxan, Cipro IV, Otiprio

Ciprofloxacin belongs to a class of antibiotics called fluoroquinolones. It's prescribed to treat bacterial infections in many parts of the body — including the urinary tract, skin, lungs, bones, joints, and digestive system. It's also used to protect against or treat anthrax and plague after exposure.

Because ciprofloxacin carries real risks, it's reserved for milder conditions like sinus infections, simple bladder infections, and flare-ups of chronic bronchitis only when there are no safer alternatives available.
