I got 7 sessions of Cisplatin Chemo (along with 35 radiation sessions) in 2020. Mine lasted on average 5 hours. They first have to order your specific cocktail from the pharmacy on site, then they'll send saline drip intravenously along with a tiny amount of your chemo, then wait for about 40 mins to an hour to make sure your tolerating it. Once that's cleared they push through some nausea med, steroid, and pain if you need it along with starting your prescribed dose bag of chemo, which mine lasted around 3 hrs. If your labs come back showing your low or lacking in vital nutrients, they'll order those to and give along with other meds. When the IV session is complete, they'll remove IV line if you don't have port placed already, and then you're free to go. If you're getting Cisplatin be prepared to loose a lot of hearing ability and you'll also develop severe Tinnitus that does not go away. This chemo does do the job....I was stage 4 and now I'm 3 years NED❤️
