Dosage & How to Take It

Semaglutide (Wegovy or Ozempic) is typically self-administered once weekly via subcutaneous injection. Alternatively, Rybelsus is taken as a daily oral tablet. In either case, consistency is essential to maintain stable hormone levels and optimize results.

Typical Dosing Schedule

Initially, treatment begins with a low dose to allow the body to adjust. For example:

• Start: 0.25 mg per week for 4 weeks
• Then, increase to 0.5 mg per week for another 4 weeks
• After that, transition to a maintenance dose ranging from 1.0 mg to 2.4 mg per week, depending on medical guidance

Because this is a gradual escalation, it helps minimize side effects such as nausea. As a result, patients are more likely to stay consistent with treatment.
