Light Therapy and Ibuprofen lysine

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Ibuprofen lysine

Ibuprofen lysine falls under PHOTOSENSITIZING DRUGS — the group Light Therapy interacts with.

Light therapy may increase the risk for photosensitization.
Concomitant use of photosensitizing drugs with light therapy may increase the risk for phototoxicity and should be avoided.
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 idea behind this pairing. Some medicines, including NSAIDs like ibuprofen, can make your skin and eyes a little more sensitive to bright light. Light therapy is, of course, all about exposing yourself to strong light. So in theory, combining the two could raise the odds of a light-related reaction, like skin redness, irritation, or feeling like you burn more easily.

I want to be honest with you though: this concern is theoretical, based on how these drugs behave rather than on solid real-world reports. For most people taking ibuprofen short term, it's unlikely to be a big deal. Ibuprofen isn't activated by light, so this isn't about it working better or worse. If you use light therapy regularly or notice skin changes, just mention it to your pharmacist or doctor.

About Light Therapy

What is Light Therapy?

  • Seasonal affective disorder (SAD)
  • Non-seasonal depression
  • Sleep and circadian rhythm problems
  • Jet lag and shift-work sleep issues
  • Certain skin conditions

Light therapy uses controlled exposure to bright artificial light and is best supported for seasonal affective disorder, where it is a recognized treatment option. It is generally safe for most people when used as directed, but you should talk to a doctor or pharmacist first, especially if you have eye conditions, bipolar disorder, or take medicines that increase light sensitivity.

About Ibuprofen

What Is Ibuprofen Used For?

Brand name: NeoProfen

Oral ibuprofen products (tablets, coated tablets, and liquid-filled capsules) are used to temporarily relieve minor aches and pains from headache, backache, toothache, muscular aches, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever. The oral prescription tablet (Ibu) is also indicated for the signs and symptoms of rheumatoid arthritis and osteoarthritis, mild to moderate pain, and primary dysmenorrhea (painful periods).

Caldolor, an intravenous (IV) form, is approved for adults and children 3 months and older to manage mild to moderate pain, to manage moderate to severe pain alongside opioid pain medicines, and to reduce fever. A separate intravenous solution, Ibuprofen Lysine, is used specifically in premature infants to close a patent ductus arteriosus (PDA) — an abnormal blood vessel connection near the heart — when standard medical management has not worked.
