Yes. You can switch between the two, especially if you’re experiencing adverse side effects on one drug or the other. However, if you’ve been taking Ozempic, you will need to wait a full week from your last dose before beginning your first dose of Victoza.  If you’re currently on Victoza, you will need to wait 24 hours before taking your first dose of Ozempic.  Only switch medications under the guidance of your doctor, as the dosing is completely different between the two medications and it does not translate between them.  Even if you’re on the highest dose of Victoza, your doctor will probably start you on a small dose of Ozempic (and vice versa) until your body gets used to the new active ingredient.
