PHOTOSENSITIZING DRUGS

Why this applies to Dexbrompheniramine, Pseudoephedrine

Dexbrompheniramine, Pseudoephedrine falls under PHOTOSENSITIZING DRUGS — the group Wild Carrot interacts with.

Theoretically, concomitant use might result in increased photosensitivity. Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Wild Carrot and your Drixoral (dexbrompheniramine plus pseudoephedrine). Some compounds in wild carrot may make your skin more sensitive to sunlight, and certain medicines can do the same thing. The thinking is that combining the two could, in theory, leave you a bit more prone to sunburn or a rash after time outdoors.

I want to be honest, though: this is a theoretical concern based on the plant's chemistry, not on real human studies, so I wouldn't lose sleep over it. This combo doesn't change how the medicine works in your body. Just be sensible with sun protection (sunscreen, a hat, shade), and check with your pharmacist or doctor before starting wild carrot.

From our pharmacist’s overview on the Dexbrompheniramine, Pseudoephedrine page

“Ephedra is the supplement I would rule out first for anyone taking dexbrompheniramine and pseudoephedrine (Drixoral, Disophrol), an antihistamine and decongestant combination for colds and allergies.

About Wild Carrot

What is Wild Carrot?

Wild Carrot
  • Urinary and bladder complaints
  • Digestive upset and gas
  • Menstrual support
  • Supporting milk production
  • Mild diuretic (water pill) effect

Wild carrot is a traditional herb (the wild ancestor of the garden carrot) used mostly for urinary, digestive, and menstrual complaints. High-quality human studies are lacking, so its benefits are unproven, and it should be avoided in pregnancy because of traditional use to affect the uterus. Talk with your pharmacist or doctor before using it.
