Vitamins

    January 1980 in “ Side effects of drugs annual ”

    TLDR Taking too much vitamin A can cause health problems like bone pain and hair loss.
    This chapter provided an overview of the adverse effects of vitamins. It reported hypercalcemia in a patient who ingested high doses of vitamin A for a year. Hair loss was observed in psoriatic patients treated with Ro 10–9359, typically occurring in the 5th to 8th week after a total dose of 1.9 g retinoid, with improvement seen after reducing or stopping treatment. Severe psoriatic patients experienced side effects like cheilitis, palmoplantar scaling, hyperhidrosis, and diffuse hair loss. Vitamin B6 showed both dopamine-enhancing and blocking properties, reversing the therapeutic effect of dopamine in Parkinson's disease at doses of 10–20 mg. Vitamin D intoxication appeared sporadically, especially in patients treated for hypoparathyroidism, renal osteodystrophy, vitamin D-dependent rickets, and osteomalacia.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community Oral minoxidil vs Topical Minoxidil w/ Retinoic acid

      in Minoxidil  6 upvotes 8 months ago
      Topical minoxidil with retinoic acid is effective but causes scalp irritation, leading the user to consider switching to 2.5mg oral minoxidil. Oral minoxidil may cause body hair growth and heart-related side effects, so it's advised to use it under medical guidance.
