Ozempic side effects overview

Ozempic, which contains the active ingredient semaglutide, is an injectable medication primarily used to manage type 2 diabetes, with the secondary benefit of also aiding weight loss. It works by mimicking the GLP-1 hormone, helping to control insulin secretion, regulate appetite and slow gastric emptying. While Ozempic can be highly effective, it’s important to be aware of its potential side effects, interactions, and management strategies.

Common side effects of Ozempic

  • Nausea. Nausea is one of the most common side effects of Ozempic. It typically occurs when starting the medication and tends to decrease over time. To manage nausea, eat smaller, more frequent meals, avoid rich or fatty foods, and drink clear or ice-cold beverages.  
  • Diarrhoea. Diarrhoea can be managed by staying hydrated and eating bland, easy-to-digest foods like bananas, rice, applesauce, and toast. Over-the-counter anti-diarrheal medications should be discussed with a pharmacist.
  • Constipation. Increase your intake of dietary fibre, drink plenty of water, and engage in regular physical activity to manage constipation. Over-the-counter laxatives or stool softeners can be helpful if needed, for short periods of time.
  • Vomiting. To reduce vomiting, eat smaller meals and avoid lying down immediately after eating. If vomiting persists, speak to your doctor.

Less common side effects of Ozempic

  • Headaches. Staying well-hydrated, getting adequate rest, and using over-the-counter pain relievers like paracetamol or ibuprofen can help manage headaches. If headaches are severe, seek immediate medical attention.
  • Dizziness. Mild and temporary dizziness may occur rarely. This can be managed by rising slowly from sitting or lying positions, staying hydrated, and avoiding sudden movements. If dizziness is constant or severe, seek immediate medical attention.

Rare side effects of Ozempic

  • Allergic reactions. Rarely, some people experience an allergic reaction to Ozempic. Symptoms can include itching, rash, difficulty breathing, and swelling of the face, lips, or tongue. Seek medical attention immediately if you experience these symptoms. Treatment typically involves antihistamines and corticosteroids, and severe cases may require emergency intervention.
  • Pancreatitis.  Symptoms of pancreatitis (inflammation of the pancreas) include severe abdominal and/or back pain, nausea, and vomiting. If you experience these symptoms, stop taking Ozempic and seek immediate medical attention. Treatment may involve hospitalisation and supportive care.
  • Gastroparesis. Where the stomach stops moving food into the bowel symptoms include nausea, vomiting, a feeling of constant fullness and reduced bowel movements, eventually leading to abdominal pain. If you have any of these symptoms, stop taking the medication and discuss with a doctor as soon as possible.
  • Bowel obstruction. Where the bowel is blocked, patients will feel severe, often “griping” abdominal pain and will stop passing stools (poo) and air (wind). This can lead to life-threatening consequences such as bowel perforation, so patients with these symptoms should seek emergency medical attention.

Ozempic side effects with unknown incidence

  • Kidney issues. In some uncommon instances, Ozempic might lead to kidney complications. Signs to watch out for include back pain, altered urination patterns, swelling in the legs or ankles, and persistent tiredness. Should you experience any of these symptoms, it’s crucial to contact your healthcare provider right away. Management of this side effect may involve modifying your medication and regularly checking kidney function.
  • Thyroid tumours. Though infrequent, there is some research suggesting a possible association between GLP-1 receptor agonists and the development of thyroid tumours. Warning signs can include the presence of a lump in the neck, trouble swallowing, and a hoarse voice. If you observe any of these symptoms, it’s important to seek medical advice for a thorough evaluation.

Ozempic long term side effects

Long-term use of Ozempic frequently leads to gastrointestinal side effects. These include nausea, vomiting, diarrhoea, constipation, and abdominal discomfort. Although these symptoms are usually most intense at the beginning of treatment and may lessen over time, they can persist for some individuals. Ongoing gastrointestinal issues can interfere with daily activities and adherence to the medication, making it important to manage these symptoms effectively.

Like other GLP-1 receptor agonists, Ozempic has been associated with an elevated risk of gallbladder disease, including gallstones and cholecystitis. Rapid weight loss, which can occur with Ozempic use, can increase this risk further. It is crucial for long-term users to have regular blood tests of their liver function, and monitor for signs of gallbladder issues, such as severe abdominal pain, nausea, and jaundice.

Although uncommon, there is a potential risk of developing pancreatitis (inflammation of the pancreas) with Ozempic use. Symptoms of pancreatitis include intense abdominal and/or back pain, nausea, and vomiting. If pancreatitis is suspected, Ozempic should be discontinued and medical attention should be sought as an emergency. Patients with a history of pancreatitis should discuss this risk with their healthcare provider before starting the medication.

Animal studies have suggested a possible risk of thyroid C-cell tumours with prolonged use of GLP-1 receptor agonists like Ozempic. While this risk has not been confirmed in humans, individuals with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 are typically advised against using Ozempic. Regular monitoring of thyroid function is recommended for those on long-term therapy.

Ozempic can increase the risk of hypoglycemia, especially when used with other diabetes medications such as insulin or sulfonylureas. Symptoms of hypoglycemia include dizziness, sweating, confusion, and palpitations. It is essential to monitor blood glucose levels closely and adjust concurrent diabetes medications appropriately to prevent hypoglycemia. It is important to be under medical supervision, and monitor glucose levels, if glucose-lowering medication has been stopped, or replaced by, Ozempic.

Adverse effects on kidney function have been reported with GLP-1 receptor agonists, particularly in patients with pre-existing kidney conditions. Symptoms such as changes in urine output, swelling in the legs or feet, and fatigue should prompt immediate medical evaluation. Regular monitoring of kidney function is advisable for long-term users of Ozempic.

The psychological effects of long-term Ozempic use should not be ignored. Significant weight loss can change self-perception and social interactions, possibly requiring psychological support. Additionally, the need for ongoing injections can cause anxiety or stress for some individuals.

Long-term use of Ozempic can interfere with the absorption of certain nutrients, potentially leading to deficiencies. Patients should ensure they maintain a balanced diet and consider supplementation if necessary, under the guidance of a healthcare provider.

Ozempic drug interactions

Ozempic may interact with other drugs, potentially altering their effectiveness or increasing the likelihood of side effects.

  1. Insulin and oral diabetes medications. Combining Ozempic with insulin or other diabetes treatments can raise the risk of hypoglycemia (low blood sugar). Your healthcare provider may need to adjust the dosages of your diabetes medications accordingly.
  2. Blood pressure medications. Ozempic can also interact with medications prescribed for high blood pressure. This interaction might necessitate careful monitoring and possible dosage changes.
  3. Anticoagulants. There is a possible interaction between Ozempic and blood thinners such as warfarin. It might be necessary to perform more regular blood tests to monitor your blood clotting closely.

Ozempic food interactions

Certain foods and supplements can also interact with Ozempic.

  • High-fat meals. Although Ozempic is generally less influenced by food, eating meals high in fat can worsen gastrointestinal symptoms. To help prevent this, it’s best to follow a balanced diet with a low fat content.
  • Vitamins. Ozempic doesn’t significantly interfere with vitamin absorption, but it’s still essential to maintain a balanced diet that includes sufficient vitamins and minerals to support overall health.

Other medical conditions

Certain medical conditions might affect how well Ozempic works or increase the risk of side effects.

  • Gastroparesis. Individuals with delayed gastric emptying should approach Ozempic with caution, as it may worsen this condition.
  • History of pancreatitis. If you have previously experienced pancreatitis, it’s important to talk to your doctor before beginning Ozempic, as it might elevate the risk of a recurrence.
  • History of thyroid cancer. People with a personal or family history of thyroid carcinoma are advised against using Ozempic due to the potential risk of developing thyroid tumours.

Ozempic safety precautions

Taking Ozempic requires some precautions to ensure safety and effectiveness.

  • Regular monitoring. Regular check-ups with your doctor can help monitor your progress and adjust your treatment as needed. Blood tests and other assessments can track your health and response to the medication.
  • Hydration. Stay well-hydrated to help manage side effects like dizziness, nausea and constipation. Aim for at least 8 glasses of water a day.
  • Dietary guidelines. Follow a balanced diet to support overall health and minimise gastrointestinal side effects.

Ozempic overdose

Exceeding the recommended dose of Ozempic won’t enhance its effectiveness and can cause serious side effects. If you think you’ve taken too much, get medical help right away. Symptoms of an overdose may include intense nausea, vomiting, and low blood sugar (hypoglycemia). Treatment will focus on alleviating these symptoms and may require supportive care and monitoring.
