What is Ozempic Pill and Injection?

Ozempic (semaglutide) pill and injection are prescription medications used for type 2 diabetes to improve blood glucose levels and reduce the risk of heart attack, stroke, and the injection can also be used to slow kidney disease progression in certain type 2 diabetes patients.

Semaglutide, the active ingredient of Ozempic, is also used for weight loss and weight management under the brand name Wegovy.

Ozempic pills are taken once daily in the morning with water at least 30 minutes before eating food, drinking beverages or taking other oral medications.

Ozempic injection is self-administered once weekly as a subcutaneous injection (under the skin) using an Ozempic pen.

Ozempic tablets and injections are FDA-approved for type 2 diabetes in adults to:

  • improve blood sugar control
  • reduce the risk of a major cardiovascular event (MACE), such as a heart attack, stroke, or death, in type 2 diabetic patients who are at high risk for these events

Ozempic injection is also FDA approved in adults for:

  • reducing the risk of kidney function decline, kidney failure, and cardiovascular death in patients with type 2 diabetes and chronic kidney disease (CKD)

Ozempic pills and injections should be used with a reduced-calorie diet and increased physical activity.

Ozempic is a GLP-1 receptor agonist that mimics GLP-1, a hormone your body releases after you eat.

Ozempic works by:

  • Increasing insulin levels when blood sugar is high.
  • Reducing glucagon to reduce sugar release from the liver.
  • Slow stomach emptying so food leaves the stomach more gradually
  • Reduce appetite and enhance fullness, helping people eat less.

These effects help improve blood sugar levels, reduce risk of major cardiovascular events, kidney function decline, and help with weight loss.

How Should I Use This Medicine?

Ozempic Injection Instructions

You should read the Instructions for Use carefully and ask your pharmacist or doctor to explain any part you do not understand. It is important to use this medicine exactly as directed. Do not take more or less of it or more often than your doctor prescribes.

Ozempic injection is a pre-filled pen injected under the skin (subcutaneously).

  • Ozempic is usually given 1 time a week
  • It can be given with or without meals at any time of the day
  • It may be injected under the skin of the thigh, abdomen, or upper arm.
  • You should rotate the injection site for each dose.
  • If using Ozempic with insulin, you may give insulin in the same area, but they should not be given right next to each other. Do not mix insulin and Ozempic in the same injection.

The day of weekly administration can be changed if necessary, as long as the time between two doses is at least 2 days (>48 hours).

Ozempic Pill Instructions

  • Take Ozempic tablets once a day.
  • Take the tablet when you first wake up and at least 30 minutes before you eat or drink anything.
  • Take the tablet with a small amount of water (no more than 4 ounces, or 120ml). Do not take the tablets with any other liquids besides water.
  • Swallow the tablet whole and do not crush, chew, or break it.
  • After 30 minutes of taking the tablet, you may eat, drink, or take other oral medicines.

Take tablets exactly as prescribed by your doctor by following all directions on your prescription label and reading all medication guides or instruction sheets.

This medicine is usually started at a low dose that is gradually increased every 4 weeks to 30 days. Follow your doctor's dosing instructions very carefully.

Warnings

Ozempic has a boxed warning for the risk of thyroid C-cell tumors. Ozempic and medicines that work in a similar way caused thyroid tumors, including thyroid cancer, in trials with rodents. It is not known if Ozempic will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.

  • If you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath, tell your healthcare provider, as these may be symptoms of thyroid cancer.
  • If you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC), or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), you should not use this medicine.

Severe gastrointestinal adverse reactions, including stomach paralysis. Postmarketing data have shown an association between semaglutide and ileus (stomach paralysis). Because these reports are voluntary, it is not possible to estimate the frequency of these effects. Talk to a healthcare provider if you develop symptoms such as bloating, stomach cramps or pain, nausea or vomiting, constipation or diarrhea, or loss of appetite. Ozempic is not recommended for patients with severe gastroparesis.

Acute pancreatitis has been observed in patients being treated with medicines like semaglutide. If you have signs and symptoms of pancreatitis, including persistent severe abdominal pain, sometimes radiating to the back, and which may or may not be accompanied by vomiting, seek medical advice immediately.

Serious hypersensitivity reactions may occur, including anaphylaxis and angioedema. Discontinue Ozempic if hypersensitivity reactions are suspected and promptly seek medical advice.

Acute kidney injury due to volume depletion has been reported in postmarketing reports occurring in patients who experienced nausea, vomiting, or diarrhea, leading to dehydration. If you have persistent or extended nausea, vomiting, and diarrhea, you need to drink fluids to help reduce your chance of dehydration and see your healthcare provider immediately.

Diabetic retinopathy complications have been reported in a clinical trial; therefore, patients with a history of diabetic retinopathy should be monitored.

Low blood glucose levels (hypoglycemia), including severe hypoglycemia, may occur if this medicine is used with an insulin secretagogue or insulin. It may be necessary to reduce the dose of the insulin secretagogue or insulin.

Acute gallbladder disease may occur, including gallstones within the gallbladder (cholelithiasis) or inflammation of the gallbladder(cholecystitis). Gallbladder studies are indicated if these are suspected.

Pulmonary aspiration during general anesthesia or deep sedation has been reported in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures. Instruct patients to inform healthcare providers of any planned surgeries or procedures.

Before taking this medicine

You should not use this medicine if you are allergic to semaglutide or any other ingredients in this medicine, or if you have:

  • multiple endocrine neoplasia type 2 (tumors in your glands); or
  • a personal or family history of medullary thyroid carcinoma (a type of thyroid cancer).

To make sure this medicine is safe for you, tell your doctor if you:

  • have a stomach or intestinal disorder
  • have severe problems with your stomach, such as slowed emptying of your stomach (gastroparesis) or problems with digesting food
  • have or have had pancreas problems (pancreatitis)
  • are planning surgery or other procedure that requires anesthesia or deep sedation
  • have kidney disease
  • have eye problems caused by diabetes (retinopathy)
  • are pregnant or intending to become pregnant
  • are breastfeeding or intending to breastfeed.

This medicine caused thyroid tumors or thyroid cancer in animal studies. It is not known whether these effects would occur in people. Ask your doctor about your risk.

Also, talk to your healthcare provider about what side effects Ozempic may cause before you start taking it.

Pregnancy

It is not known if Ozempic will harm an unborn baby. Talk to your healthcare provider before you become pregnant because it is recommended you stop using this medicine at least 2 months before you get pregnant. If you do become pregnant while taking semaglutide, tell your healthcare provider right away.

Semaglutide may indirectly improve fertility by promoting weight loss and better blood sugar control (see Ozempic babies: Does Ozempic increase fertility?).

Talk to your healthcare provider about the best way to control your blood sugar if you plan to become pregnant or while you are pregnant.

Breastfeeding

It is not known if Ozempic passes into your breast milk. You should talk with your healthcare provider about the best way to feed your baby while using the injection. Breastfeeding is not recommended during treatment with Ozempic tablets.

Ozempic Side Effects

Common Ozempic side effects

Common Ozempic side effects include nausea, vomiting, decreased appetite, diarrhea, abdominal pain, and constipation, which occurred in 5% or more of patients.

Serious Ozempic side effects

Ozempic has a boxed warning for the risk of thyroid C-cell tumors. A boxed warning is the strongest safety-related warning issued by the FDA.

Ozempic can cause serious side effects, such as inflammation of the pancreas, vision changes, low blood sugar levels, kidney problems, and serious allergic reactions, and it can also increase the risk of food or liquid getting into your lungs during surgery or a medical procedure. See the warning section for more details on these serious side effects and the risk of thyroid C-cell tumors.

Get emergency medical help if you have signs of an allergic reaction, such as hives, itching, dizziness, fast heartbeats, difficulty breathing, or swelling of your face, lips, tongue, or throat.

This medicine can cause other serious side effects. Call your healthcare provider at once if you have:

  • vision changes;
  • pounding heartbeats or fluttering in your chest;
  • a light-headed feeling, like you might pass out;
  • signs of a thyroid tumor - swelling or a lump in your neck, trouble swallowing, a hoarse voice, feeling short of breath;
  • symptoms of pancreatitis - severe pain in your upper stomach spreading to your back, nausea with or without vomiting, fast heart rate;
  • gallbladder problems - upper stomach pain, fever, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • low blood sugar - headache, hunger, weakness, sweating, confusion, irritability, dizziness, fast heart rate, or feeling jittery;
  • kidney problems - swelling, urinating less, blood in urine, feeling tired or short of breath
  • stomach flu symptoms - stomach cramps, vomiting, loss of appetite, diarrhea (may be watery or bloody)
  • symptoms of stomach paralysis (ileus) - bloating, stomach cramps or pain, nausea or vomiting, constipation or diarrhea, loss of appetite.
  • Food or liquid getting into the lungs during surgery or other procedures that require anesthesia or deep sedation. Ozempic may increase the chance of food getting into your lungs during surgery or other procedures. Tell all your healthcare providers that you are taking this medicine before you are scheduled to have surgery or other procedures.

Also see “What are the long-term side effects of Ozempic?”

This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Following these tips may help you manage stomach side effects:

  • eat more slowly
  • consume smaller meals
  • select more bland, low-fat foods (like crackers, toast, and rice)
  • avoid greasy, fried foods or sugar treats
  • eat foods that contain water (like soup or gelatin)
  • don’t lie down right after eating
  • drink clear or ice-cold liquids
  • if possible, go outside for fresh air if you feel sick to your stomach.

Ozempic and type 2 diabetes

In the SUSTAIN 1 trial (NCT02054897), 73% of people with type 2 diabetes taking Ozempic 0.5 mg injection reached an A1C of 7% or less within 30 weeks.

Ozempic for CKD and heart disease

The FLOW phase 3b clinical trial (NCT03819153) demonstrated that when Ozempic 1 mg injection was used in adults with type 2 diabetes and CKD, Ozempic demonstrated:

  • 24% reduced the risk of kidney disease progression, kidney failure, and cardiovascular death at 3 years when compared to placebo.

Ozempic for weight loss

Ozempic’s active ingredient, semaglutide, is used for weight loss and weight management, under the brand name Wegovy.

Semaglutide, the active ingredient in Ozempic injection, was shown to be effective for weight loss in a 30-week semaglutide SUSTAIN 1 clinical trial (NCT02054897). Semaglutide patients had:

  • 7.7 lbs (3.5 kg) more weight loss than placebo (with a 1 mg injection dose)
  • 5.7 lbs (2.6 kg) more weight loss than placebo (with a 0.5 mg injection dose)

Ozempic injection helped with weight loss and weight loss maintenance when used with diet and exercise in clinical trials, however, it is not FDA-approved for weight loss. Wegovy is the brand of semaglutide approved for weight loss. See Wegovy vs Ozempic: Which is right for you? Or Ozempic for weight loss, for more information.

What other drugs will affect Ozempic?

This medicine can slow your digestion, and it may take longer for your body to absorb any medicines you take by mouth.

Tell your doctor about all your other prescription and over-the-counter medicines, especially insulin or other diabetes medicines, such as dulaglutide, exenatide, liraglutide, Byetta, Trulicity, Victoza, and others. There is an increased risk of hypoglycemia (low blood sugar) when Ozempic is used in combination with insulin or other diabetes medications such as glyburide, glipizide, glimepiride, or gliclazide. The dosage of these other agents may need to be reduced to lower the risk of low blood sugar levels.

Drinking alcohol while taking this medicine may be risky, see Can I drink alcohol on Ozempic?.

Other drugs, including prescription and over-the-counter medicines, vitamins, and herbal products, may affect this medicine. Tell your healthcare provider about all the other medicines you take.

Common questions about Ozempic

Mounjaro vs Ozempic: Which is right for you?
Mounjaro and Ozempic are both once-weekly shots approved to treat type 2 diabetes in adults. Mounjaro (tirzepatide) copies two gut hormones, GIP and GLP-1. Ozempic (semaglutide) copies just one. In head-to-head studies, Mounjaro lowered blood sugar and body weight more. Both now also lower heart risk, but neither is approved for weight loss on its own. Continue reading
Which GLP-1 drug is best for weight loss?
The most effective GLP-1 drug for weight loss currently (as of early 2026) is tirzepatide, marketed under the names Zepbound (for weight loss) and Mounjaro (for diabetes). Clinical trials and recent meta-analyses consistently show tirzepatide delivers the most substantial weight reduction among GLP-1 medications, with average losses of up to 22.5% of body weight. Continue reading
What are the long-term side effects of Ozempic?
Ozempic has the potential to cause certain long-term problems that may last months or years after stopping it. Some examples of long-term side effects you may experience from Ozempic include pancreatitis, vision problems, acute kidney injury, and acute gallbladder disease. Continue reading
How many doses are in an Ozempic pen?
Ozempic pens come in 3 sizes. Each pen holds 4 maintenance doses of either 0.5 mg, 1 mg, or 2 mg of medicine given once weekly and will last for one month. This pen is a device that is pre-filled with medication and makes it easier for you to give yourself the weekly injections. Continue reading
Wegovy vs Ozempic: Which is Right for You?
Both Wegovy and Ozempic contain the GLP-1 agonist semaglutide, but Wegovy is prescribed for long-term weight management and certain forms of liver disease, while Ozempic is used to control blood sugar in type 2 diabetes and help protect the heart and kidneys. They both lower the risk for heart-related complications, but differ in other approved uses and populations, side effects, dosage forms and costs. Continue reading
How long does it take for Ozempic to work?
Your blood glucose (sugar) levels should start to decline within the first days to a week after you start using Ozempic (semaglutide). You will start with lower doses for the first 4 weeks of treatment to help reduce initial stomach side effects, but this is not an effective dose to lower blood sugar over the long-term. The full effect can take 12 weeks or longer, depending upon how well you tolerate the medicine. Continue reading
Can you switch between Ozempic and Mounjaro?
Yes, you can switch between Ozempic and Mounjaro under the supervision of a healthcare professional. There is no one way to switch that is recommended for everyone. Your healthcare provider will consider the reason you are stopping, how long you have been taking your current medication, and the date of your last dose when deciding the best way to switch between these medications. Continue reading
How does Ozempic work for weight loss?
Ozempic (semaglutide) can help you lose weight by reducing hunger, increasing feelings of fullness, and helping you eat fewer calories. It works like the natural GLP-1 hormone to regulate appetite and food intake. Ozempic also slows stomach emptying, but this does not fully explain its effects on long-term weight loss. Continue reading
Do Ozempic, Wegovy, Mounjaro & Zepbound cause hair loss?
There’s no evidence that hair loss is a direct side effect of Ozempic, Wegovy, Mounjaro or Zepbound. Hair loss is more likely due to the stress of rapid weight loss on your body, which can lead to temporary shedding of hair over several months, a condition known as telogen effluvium. Continue reading
