Very bad disgusting service

My helper went to the clinic just for a headache. Test were done. She is given pain medication together with prep hetemict 200 mg. She is told tjis is to help you prevent getting HIV. No conversation these are tablets where one has to make a decision after a conversation because they have to take them forever. So why just lightly decided as a health provider to give a person these and not even explain to the patient. No my sister is sick with suffer effects of these that she doesn't even what it's for. Princess stuff is really unprofessional. All she knows is everyone that tested nagative takes these! What nonsense is this. Patient goes in for a mere headache, they don't know if this person yet you just give her meds that is going to change her life. Why are the nurses there so Flippin judgemental,
