Ozempic (Semaglutide) Injection: Uses, Side Effects, Dosage


Erica Prouty, PharmD, is a professional pharmacist assisting patients with medication and pharmacy services in North Adams, Massachusetts.
In non-human animal studies, semaglutide has been shown to cause C-cell thyroid tumors in rodents. However, it is unclear whether this risk extends to humans. However, semaglutide should not be used in people with a personal or family history of medullary thyroid cancer or in people with multiple endocrine neoplasia type 2 syndrome.
Ozempic (semaglutide) is a prescription drug used along with diet and exercise to control blood sugar levels in people with type 2 diabetes. It is also used to reduce the risk of serious cardiovascular events such as stroke or heart attack in adults with type 2 diabetes and heart disease.
Ozone is not insulin. It works by helping the pancreas release insulin when blood sugar levels are high and by preventing the liver from making and releasing too much sugar. Ozone also slows down the movement of food through the stomach, reducing appetite and causing weight loss. Ozempic belongs to a class of drugs called glucagon-like peptide 1 (GLP-1) receptor agonists.
Ozempic does not cure type 1 diabetes. Use in patients with pancreatitis (inflammation of the pancreas) has not been studied.
Before you start taking Ozempic, read the patient information leaflet with your prescription and ask your doctor or pharmacist any questions you may have.
Be sure to take this medicine as directed. People usually start with the lowest dose and increase it gradually as directed by their health care provider. However, you should not change your dose of Ozempic without talking to your healthcare professional.
Ozempic is a subcutaneous injection. This means that it is injected under the skin of the thigh, upper arm, or abdomen. People usually get their weekly dose on the same day of the week. Your healthcare provider will tell you where to inject your dose.
Ozempic’s ingredient, semaglutide, is also available in tablet form under the brand name Rybelsus and in another injectable form under the brand name Wegovy. Do not use different types of semaglutide at the same time.
Ask your health care provider how often you should check your blood sugar. If your blood sugar is too low, you may feel chills, hunger, or dizziness. Your health care provider will tell you how to treat low blood sugar, usually with a small amount of apple juice or fast-acting glucose tablets. Some people also use prescription glucagon by injection or nasal spray to treat severe emergency cases of hypoglycemia.
Store Ozempic in the original packaging in the refrigerator, protected from light. Do not use expired or frozen pens.
You can reuse the pen several times with a new needle for each dose. Never reuse injection needles. After using the pen, remove the needle and place the used needle in a sharps container for proper disposal. Sharps disposal containers are commonly available from pharmacies, medical supply companies, and health care providers. According to the FDA, if a sharps disposal container is not available, you can use a household container that meets the following requirements:
When you’re done using the pen, put the cap back on and place it back in the refrigerator or at room temperature. Keep it away from heat or light. Throw away the pen 56 days after first use or if there are less than 0.25 milligrams (mg) left (as indicated on the dose counter).
Keep Ozempic away from children and pets. Never share an Ozempic pen with other people, even if you are changing the needle.
Health care providers may use Ozempic off-label, meaning in situations not specifically identified by the FDA. Semaglutide is also sometimes used to help people manage their weight through a combination of diet and exercise.
After the first dose, Ozempic takes one to three days to reach maximum levels in the body. However, Ozempic does not lower blood sugar at the initial dose. You may need to have your blood sugar checked after eight weeks of treatment. If your dose is not working at this stage, your healthcare provider may increase your weekly dose again.
