    TLDR Most patients on isotretinoin for acne experience mild, dose-related side effects, but the connection to depression or bowel disease is uncertain.
    The study conducted by Małgorzata Drozd and colleagues in 2020 aimed to evaluate the prevalence of adverse effects in patients treated with isotretinoin, a vitamin A-derivative used for acne vulgaris treatment. The study involved a survey of 196 Polish patients who had been treated with isotretinoin. The most common side effects reported were mucocutaneous effects such as dry lip (92.6%), dryness of the mucous membranes (73.5%), xerodermia (66.8%), and dryness of the conjunctiva (66.3%). Other reported side effects included tiredness and back pain (70.4%), myalgia (55.1%), arthralgia (32.1%), stiffness of joints (26.0%), mood change (54.6%), hair loss (50.0%), and gastrointestinal symptoms (15.8% - 10.7%). The study concluded that while these side effects were usually mild and dose-dependent, their prevalence was very high. The link between isotretinoin and depression or suicidality remained unclear, and the risk of inflammatory bowel disease was probably not increased in patients exposed to isotretinoin. However, the authors suggested that more studies were necessary.

      A user is experiencing rapid hair loss and has been diagnosed with telogen effluvium by multiple dermatologists, but doubts the diagnosis due to the severity and speed of the hair loss. They are considering various treatments like spironolactone, estradiol, and possibly finasteride, while also exploring the possibility of hormonal imbalances or autoimmune issues.

      community Tretinoin for some men(not all) can cause non-telogen effluvium hair loss

      in Research/Science  6 upvotes 4 months ago
      Tretinoin can cause non-telogen hair loss in some men by inducing catagen-like changes in hair follicles and through retinoid toxicity, especially when used with minoxidil. Some users report hair loss even when using retinoids on the face, while others experience benefits when combined with treatments like finasteride and minoxidil.

      community What’s the consensus on tretinoin?

      in Treatment  7 upvotes 1 year ago
      Tretinoin may increase minoxidil absorption but could potentially worsen hair loss over time. Users discuss applying 0.5% tretinoin gel to the hairline/scalp with minoxidil.
