You have to be consistent in taking the PN Pills. For your next appt do inform them that you require extra to last the weeks ahead because the last time given it wasn't enough.
You can get alternative at external pharmacy if u do nt want to wait. It's OK to pause awhile too, I was sick n stop them for a week as I was on medication.
You can write in and ask for a topup then delivery/self collect your medication at KKH
