It is quite common to experience sexual side effects with your current medications. Both amitriptyline and propranolol are well-known contributors to sexual dysfunction, and clonazepam can also play a minor role. Please do not stop taking these medications abruptly, as doing so can cause withdrawal symptoms. Instead, consult your doctor. They can safely manage this by either adjusting your dosages or switching you to alternatives. For example, amitriptyline can often be replaced with an antidepressant like bupropion, which carries a much lower risk of sexual side effects. Rest assured, this is a very common, reversible issue that your doctor can easily help you resolve.
