Hi,
There is no phototoxic or photo-sensitive known effect of Synthroid. Also, there are very few reported cases of
Wellbutrin causing
photosensitivity in medical literature. Also, there is no known interaction between Wellbutrin and Synthroid, if being used together. Otherwise, also this do not seem a case of photo-sensitivity, as there is no swelling, burning or blisters / vesicle like rash, which are usually present in Sun-sensitivity cases.
Hence, by all means, it seems a case of
atopic allergy to atmospheric allergens (As present in open parts of body than covered parts). Hence, use of anti-allergic like
Cetirizine or Loratadine etc. orally may be needed for this. Use of local steroid cream like
Hydrocortisone may relieve the patient of symptoms of itching, redness etc.
Take care. Hope I have answered your question. Let me know if I can assist you further.
