Need advice on new medication and its effects

I have recently been put on this new medication after an extended admission - the discharge options were picc line + daily IV fluids or get on this drug. Thankfully I was able to access the medication through a scheme with the Royal Adelaide Hospital (the only place in the state where you can access the drug). I haven't been given too much information as to side effects, how do I know it's working, what it even does 😅😅 (my specialist had finished his rotation by the time I had accessed the medication, the specialist on rotation had no clue) Any other Droxidopa users?
