About the Mounjaro 2.5mg Dose

The 2.5mg dose is the starting dose for all Mounjaro patients. You will typically remain on this dose for the first 4 weeks as your body adjusts to the medication. This introductory period helps minimise side effects such as nausea and digestive discomfort. Your prescriber will then increase your dose to 5mg. Because this is a universal starting point, it is available from the widest range of pharmacies and often attracts the most competitive pricing, especially from online providers looking to win new customers with introductory offers.
