Like all weight loss injections, Retatrutide and Tirzepatide may cause mild to moderate side effects—most commonly nausea, stomach discomfort, diarrhoea, constipation, and injection site reactions such as swelling or redness. Headaches, dizziness, and rare but serious risks such as pancreatitis may occur.
Most people find that side effects decrease as the body adjusts to the medication. Users should follow the titration schedule, starting at lower doses and gradually increasing, to minimise discomfort. Anyone experiencing severe or lasting symptoms should contact their healthcare professional promptly
