Mounjaro Kwikpen

Some people experience side effects while using Mounjaro. Very common side effects can include nausea, diarrhoea, vomiting, stomach pain and constipation.

Common side effects can include indigestion, bloating, burping, wind, reflux, heartburn, dizziness, low blood pressure, tiredness, injection site reactions, allergic-type skin reactions, fast pulse, gallstones, hair loss, increased pancreatic enzymes, altered taste and changes in skin sensation.

Stomach-related side effects are more common when starting treatment or increasing the dose. They may improve over time, but persistent, severe or worsening symptoms should be reviewed.

Mounjaro can cause nausea, vomiting or diarrhoea, which may lead to dehydration. This is particularly important if you have kidney problems. Drink enough fluids and seek clinical advice if you cannot keep fluids down or feel dehydrated.

Stop using Mounjaro and seek urgent medical advice if you develop severe, persistent stomach pain, with or without nausea and vomiting. This may be a sign of acute pancreatitis, which can be serious.

Seek urgent medical help if you develop signs of a serious allergic reaction, such as swelling of the face, lips, tongue or throat, difficulty swallowing, breathing difficulty, wheezing, fast heartbeat, severe rash, dizziness, fainting or collapse.

If you have diabetes and use insulin or a sulfonylurea, Mounjaro may increase the risk of low blood sugar. Your diabetes medicines may need review. Symptoms of low blood sugar can include sweating, shaking, hunger, headache, drowsiness, weakness, dizziness, confusion, irritability and fast heartbeat.

Mounjaro may not be suitable if you have a history of pancreatitis, severe digestive problems, severe gastroparesis, diabetic eye disease, macular oedema, significant kidney problems, gallbladder disease, eating disorder history, or if you are due to have surgery under anaesthesia.

Do not use Mounjaro if you are pregnant. If you are pregnant, think you may be pregnant or are planning a pregnancy, seek clinical advice before using this medicine.

Women using oral contraceptives may need additional barrier contraception or a non-oral contraceptive method for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase, because Mounjaro may affect how oral contraceptives are absorbed.

If you are breastfeeding or planning to breastfeed, speak to a clinician before using or continuing Mounjaro.

Tell your clinician about all medicines you take, including prescription medicines, over-the-counter medicines, supplements and herbal products. This is especially important if you take diabetes medicines, anticoagulants, oral contraceptives or medicines affected by delayed stomach emptying.

Mounjaro is not suitable for weight management in children or adolescents under 18 years.

Store Mounjaro in a refrigerator between 2°C and 8°C before use. Do not freeze. After first use, the pen can be stored unrefrigerated below 30°C for up to 30 days, then it must be discarded.
