Do side effects taper off after getting used to a dosage?

So recently with my doctors approval I’ve increased from 100mg to 150mg about 3 days ago to try and take care of small pimples I keep getting. So far I’ve been experiencing more side effects, like dryness of my skin, thirst, and feeling dizzy. Do these side effects ever taper off after getting used to a dosage or should I expect this the entire time I’m taking 150mg.
