Hi, Hot flashes are a known side effect of Paxil CR (paroxetine), which is a type of antidepressant medication called a selective serotonin reuptake inhibitor (SSRI). Hot flashes are more commonly associated with menopause in women, but they can also occur in men and be caused by medications like Paxil CR. If you are experiencing hot flashes as a side effect of Paxil CR, it is important to speak with your healthcare provider before making any changes to your medication regimen. Stopping Paxil CR abruptly can lead to withdrawal symptoms, so it is important to taper off the medication under medical supervision. Your healthcare provider may be able to adjust your dosage or switch you to a different medication to help alleviate your hot flashes while still managing your anxiety and PTSD symptoms. It is also possible that other factors could be contributing to your symptoms, so it is important to have a thorough evaluation with your healthcare provider to determine the underlying cause and the best course of treatment. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
