Long-Term Opioid Adverse Drug Reaction Management in Cancer Patients

Italian researchers have reviewed the impact of various drugs on hair disorders, identifying that a significant number of medications can disrupt the hair cycle, leading to conditions such as alopecia, hirsutism, or hypertrichosis. Anagen effluvium, characterized by a rapid cessation of cell division in hair matrix cells, is a common side effect of cancer treatments, with nearly 100% of patients experiencing substantial hair loss shortly after drug administration. Telogen effluvium, another form of drug-induced hair loss, occurs when hair follicles enter the resting phase too early, typically becoming noticeable 2-4 months after starting treatment with drugs like anticoagulants, retinoids, interferons, and antihyperlipidemics, or 2-3 months following the cessation of oral contraceptives. Drug-induced alopecia is generally reversible once the medication is stopped. The likelihood and severity of hair loss depend on both the drug and the individual's susceptibility. Regarding drug-induced hair growth, hirsutism can be caused by drugs such as testosterone and corticosteroids, while hypertrichosis is often a side effect of medications like cyclosporin and minoxidil, with the extent of hair growth typically dose-dependent and reversible upon discontinuation of the drug.
