Is increasing dosage necessary?

Currently taking 2.5mg Zepbound, I am doing well with that. Currently have lost roughly 5ish pounds within a month. Male, 230 pounds. I am wanting to get down to 200 pounds, so I'd like to lose another 30 pounds. Do I need to continue increasing my dosage or could I keep taking the 2.5mg to get to my goal? Once I reach 200, what happens with the Zepbound? Do I need to continue taking it or can I stop?
