Common side effects of semaglutide include swelling, redness, itching at the injection site, tiredness, nausea, vomiting, diarrhoea, or constipation. Nausea tends to improve with continued use of semaglutide. If any of these side effects persist or worsen, it is important to inform your healthcare provider promptly. If you experience any severe side effects, such as changes in urine output or vision problems like decreased or blurred vision, persistent nausea or vomiting, or severe stomach or abdominal pain, seek immediate medical assistance as this could indicate pancreas or gallbladder issues.

While semaglutide doesn’t cause low blood sugar levels, it may occur if you are also taking other diabetes medications. It is advisable to discuss with your healthcare provider whether the dosage of your other diabetes medications needs to be adjusted. Low blood sugar levels can also result from excessive alcohol consumption, inadequate calorie intake, or strenuous exercise. Symptoms of low blood sugar may include sudden sweating, shaking, rapid heartbeat, hunger, blurred vision, dizziness, headache, or tingling in the hands or feet. If you experience symptoms of high blood sugar (hyperglycaemia), it is important to notify your doctor immediately, as a dosage adjustment may be necessary.


Before taking Semaglutide, it’s best to discuss with your healthcare provider any allergies you have. This product may contain inactive ingredients, which can cause allergic reactions or other problems. You should also mention the medical history of you and your family, especially of: a certain eye problem (diabetic retinopathy), a disease of the pancreas (pancreatitis), gallbladder disease, kidney problems, and stomach/intestinal disorders, or medullary thyroid carcinoma (a type of thyroid cancer), also discuss the products you use including prescription/nonprescription drugs and herbal products.

It’s recommended to stop taking Ozempic 2 months before a planned pregnancy. If you are planning pregnancy, become pregnant, or think you may be pregnant, discuss with your healthcare provider immediately. It is unknown if this medication passes into breast milk, but consult your healthcare professional before breastfeeding. 

How to reduce side effects 

Most side effects can be managed and usually go away on their own after a few days or weeks. The best way to minimise the chances of experiencing nausea and vomiting from Ozempic is to start with a lower dose and increase it slowly over time. Doing so will allow your body to become accustomed to the medicine at its lowest dose, reducing the risk of experiencing those unpleasant side effects. Additionally, what you eat can reduce any unpleasantries, eating large or fatty meals while taking the drug can worsen nausea and vomiting, so it’s advised that patients avoid them as much as possible. Taking precautions when taking any prescription medicine is essential for minimising unwanted side effects and ensuring effective treatment. With that in mind, following the instructions related to starting with low doses and slowly increasing them has been reported by patients as helpful in reducing their chances of short-term negative reactions. 


Please adhere strictly to the prescribed dosage advised by your healthcare professional. Taking more than the recommended doses can lead to hypoglycaemia, a prolonged and significant decrease in blood sugar levels. It is crucial to regularly monitor your blood sugar levels to ensure they remain stable. If you require a higher dose, it is important to consult your healthcare provider. They may consider replacing your current pen with a higher-strength option, containing 8 mg/3 mL per pen.
