How to use the Wegovy Pen

The starting dose of Wegovy is 0.25 mg once a week for 4 weeks of treatment, then increasing over 16 weeks until you reach the maintenance dose of 2.4 mg per weekly injection. It is important to only change the dose under the advice of your doctor as they will be able to monitor how you are feeling during treatment and make any necessary adjustments depending on your situation. A Wegovy pen usually lasts about a month when taken at the normal dose; however, if your doctor recommends that you increase or decrease the regular amount of medication taken, it may last longer or shorter periods depending on how much you need to adjust for your individual health needs.

To administer, select a suitable injection site from the following body areas: upper arms, upper legs, or stomach (ensure a 5 cm distance from your belly button). You have the option to inject in the same body area each week, but be sure to avoid using the exact spot as in the previous injection. Place the pen in a straight alignment against your body, ensuring the pen’s window is visible to you. Apply gentle pressure as you push the pen firmly against your skin until you hear a distinct click sound. This indicates that the injection has commenced. Keep an eye on the pen’s window, and you’ll notice the yellow bar within it begin to move. If the yellow bar doesn’t move initially, apply a bit more pressure against your skin to initiate the injection process. The injection takes about 5–10 seconds.

Possible common side effects 

It’s important to stick to the dose escalation schedule to reduce any of these side effects; nausea, diarrhoea, vomiting, constipation, stomach pain, headache, fatigue, upset stomach, dizziness, bloating, belching, gas, stomach flu, and heartburn. Should you encounter any side effect that troubles you or persists, don’t hesitate to share it with your healthcare provider.

Is Wegovy the same as Ozempic?

Wegovy and Ozempic are identical medications (the active ingredient is semaglutide) but marketed under distinct brand names. The primary distinction lies in the amount of semaglutide contained in each pen and the purposes for which they have been approved. Initially, semaglutide gained approval as Ozempic in 2017, designated as a treatment for type 2 diabetes. Subsequently, in 2021, the FDA approved the same drug under the brand name Wegovy specifically as a weight loss medication. It is common for doctors to prescribe both Wegovy and Ozempic to aid in weight loss efforts. Wegovy maintenance dose is 2mg whereas Wagovy has a 2.4mg dose.
