Lime and Oxytetracycline , Polymyxin B

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Oxytetracycline , Polymyxin B

Oxytetracycline , Polymyxin B falls under PHOTOSENSITIZING DRUGS — the group Lime interacts with.

Theoretically, concomitant use of lime oil with photosensitizing drugs may increase the risk of phototoxicity.
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

Terak is an eye and skin ointment that combines two antibiotics, oxytetracycline and polymyxin B. The tetracycline part has a known quirk: it can make your skin more sensitive to sunlight, so you may sunburn faster or break out in a rash on sun-exposed areas. That is the photosensitizing effect we are talking about here.

Lime oil, especially the concentrated essential oil applied to skin, also carries plant compounds that can react with sunlight. In theory, stacking the two could add up and raise your odds of a sun reaction. This is based only on lab data, so it is a soft concern, not a proven problem. A wedge of lime in your drink is unlikely to matter. If you are using lime oil topically while on Terak, mention it to your pharmacist and just be smart about sun protection.

From our pharmacist’s overview on the Oxytetracycline , Polymyxin B page

“St. John's wort is the entry I'd check first for anyone using Terak (oxytetracycline with polymyxin B), since both the herb and this antibiotic's tetracycline component can make skin react more strongly to sunlight.”

About Lime

What is Lime?

Lime
  • Source of vitamin C
  • Digestive upset
  • Skin care
  • Mood and aromatherapy
  • Flavoring and food preservation

Lime is a common citrus fruit and a good natural source of vitamin C and plant antioxidants. As a food it is generally safe and enjoyed by most people, but evidence that lime treats any specific health condition is limited. Use the essential oil with care, and check with your pharmacist or doctor before using concentrated lime products for health reasons.
