One pen lasts for a month, and you’ll use it once a week. You’ll be prescribed the lowest strength pen first, and then move up to the next Wegovy dose every month until you reach a maintenance amount that works for you.
Weight loss moves at a different speed for everyone. A clinician might decide you only need to move up a dose once or twice before you strike the right balance. There’s no fixed agenda, so the rate you increase your pens will depend on how you respond to Wegovy. It’s flexible in that way. Because your weight loss goals are personal, you can decide when you’ve reached a dose that controls your hunger spikes and helps you reach a healthy weight at a rate you’re comfortable with.
