ozempic in Singapore


Ozempic has been hitting the headlines as a revolutionary weight loss drug for good reason! But before taking this medication, you first need to consult with a registered weight loss doctor who is knowledgeable in the safe use of Ozempic in Singapore. Ozempic and Wegovy are the brand names for the medication, the drug name is semaglutide. This once-weekly injection is incredibly effective at helping people lose weight. In this guide, I will provide an overview of how it is used and what you can expect when you start using it.

What is Ozempic (Semaglutide) and how does it work? 

Ozempic (Semaglutide) is an injectable medication that is given once weekly and belongs to the class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists.  Rybelsus is the daily oral formulation of Semaglutide. GLP-1 is a naturally occurring hormone that is secreted by your intestines after a meal. It has multiple actions:

  • Stimulates insulin secretion depending on your blood sugar levels
  • Delays emptying of your stomach
  • Reduces appetite
  • Reduce glucose production by the liver
  • Slow glucose absorption by the intestine

However, naturally occurring GLP-1 only hangs about 15 minutes before it is broken down by the body. This is where drug companies stepped in and made longer-acting versions of GLP-1.  You might have heard of Saxenda (liraglutide), this was a GLP-1 that lasted over 24 hours, used to treat weight loss with daily injections. Ozempic (semaglutide) lasts even longer so only requires an injection once every week. The oral formulation of Semaglutide is called Rybelsus. The weight loss preparation which is not available in Singapore is called Wegovy.


GLP-1 agonists were initially developed as diabetic treatments, and for this, they are very effective. However, it was noted how effective they were for weight loss so they were also studied specifically for weight loss in patients without diabetes. But in order to achieve the best results, be sure to consult with a healthcare professional who has expertise in weight loss and is knowledgeable in the safe use and administration of semaglutide in Singapore.


Rybelsus Vs Ozempic

Rybelsus and Ozempic have emerged as key actors in diabetes control and weight loss. Although both drugs include the active component Semaglutide, their administration routes and specific purposes differ significantly. This section, written from a cardiologist’s perspective, seeks to clarify the differences and similarities between Rybelsus and Ozempic, thereby increasing the general public’s comprehension of these alternatives within Singapore’s medical context.


Semaglutide: The Main Denominator


The active ingredient in Rybelsus and Ozempic is semaglutide, which is a GLP-1 receptor agonist. This class of medicines stimulates insulin secretion in response to high blood sugar levels, assisting in the efficient treatment of Type 2 Diabetes Mellitus. Furthermore, Semaglutide’s role in weight regulation, which includes appetite suppression and delayed stomach emptying, has cleared the road for its usage in obesity treatment.


Rybelsus: The Oral Pioneer

Rybelsus is the first orally given GLP-1 receptor agonist. It is intended for people who prefer the convenience of pills versus injections. Rybelsus should be started gradually to reduce the risk of gastrointestinal adverse effects, which are prevalent with GLP-1 receptor agonists. This incremental adjustment improves patient compliance and tolerance to the medicine.


Rybelsus has the following key features:

  • Administration: Oral, usually taken once daily on an empty stomach.
  • Indications: Primarily used to control Type 2 Diabetes, with a secondary focus on weight loss in diabetic patients.
  • Dosage adjustments: Use a step-up technique to lessen the risk of stomach discomfort.

Ozempic: The Injectable Contender

Ozempic, on the other hand, is injected subcutaneously, making it an appropriate option for people who do not respond well to oral treatments or require a higher dose of Semaglutide. The injectable form provides for a slower, more regulated release of the medicine, which may contribute to increased efficacy in decreasing blood sugar levels and aiding in weight loss.


The key features of Ozempic are:

  • Administration: Subcutaneous injection, usually once per week.
  • Indications: Used to control Type 2 Diabetes, with considerable benefits for cardiovascular risk reduction and weight management.
  • Dosage Flexibility: Provides a larger range of dosing alternatives to address patient-specific demands and reactions.

Rybelsus vs Ozempic: Comparing the Two

While both drugs contain the same active component, they differ in route of administration, dose frequency, and patient preferences and needs.


  • Route of Administration and Compliance: Rybelsus’s oral administration and compliance may appeal to those who are averse to injections. Those who prefer fewer frequent dosing schedules may find Ozempic’s once-weekly injection more convenient.
  • Efficacy and Dosage: Ozempic’s injectable form of Semaglutide may provide a more consistent and potent delivery of the drug, potentially leading to more significant improvements in blood glucose control and weight loss, particularly in people with higher baseline levels or who have not responded well to oral therapies.
  • Patient-Specific Considerations: The decision between Rybelsus and Ozempic is frequently influenced by particular patient characteristics such as lifestyle, medical history, and treatment objectives. For example, people with gastrointestinal sensitivity may find Ozempic more tolerable, whilst those with needle fear may choose Rybelsus.

Choosing between Rybelsus and Ozempic requires a thorough evaluation of a patient’s health history and goals. These medications offer important advances in the treatment of Type 2 diabetes and obesity, with the potential for improved health outcomes.

Is Ozempic safe in patients with heart conditions?

You might be wondering why Ozempic is on a cardiologists web page.  Lots of heart patients have conditions caused by obesity, such as hypertension, high cholesterol and diabetes.  We use Ozempic because it is safe in patients with heart conditions. 


In fact, the latest news looks even better than just safe! Novo Nordisk published in August 2023 that in their new trial called SELECT, Semaglutide lowered the risk of heart attack, stroke and death by 20%!  This makes Wegovy the first obesity drug that actually prevents adverse events. This is big news and opens up these drugs to a much wider patient base that could benefit from them.

Are GLP-1 agonists effective for weight loss?

These medications have been studied in large clinical trials and have been shown to help weight loss when compared to placebo.

It is important to note they are not “wonder drugs”, and if you don’t try and eat a restricted and healthy diet then you will struggle to lose weight. In both these studies the medication was given alongside a diet and exercise program with behavioural modification.  

When is Ozempic (Semaglutide) Used?

Ozempic is used in 2 main groups of patients

  1. Diabetes type 2 – Ozempic (Semaglutide) is used in adults with type 2 diabetes who are not able to achieve their target blood sugar level using other medications. Ozempic is often used with the goal of improving control of blood sugar and reducing the risk of any complications associated with high sugar levels including nerve damage, kidney damage, and heart disease.
  2. Weight loss – Semaglutide can be used in people with a body mass index (BMI) greater than 30 or those with a BMI > 27 if they also have an obesity-related condition like high blood pressure or high cholesterol.

How to Take Ozempic (Semaglutide)?

Ozempic is typically taken once per week as a subcutaneous injection, and here are the general instruction for taking it:

  1. Wash your hands thoroughly with soap and water.
  2. Look for a clean, dry area on your upper leg, stomach, or upper arm where you can inject the medication into some fat just under the skin.
  3. Remove the cap of the pen and check the solution in it for any discoloration or particles. 
  4. Attach a new needle.
  5. Dial in the dose you have been prescribed.
  6. Pinch a fold of your skin where you want to inject the solution and hold the pen at a 90-degree angle to your skin.
  7. Press the plunger down to inject the medication.
  8. When the dose counter reaches zero, slowly count to 6 then pull out the skin.

Interactions with Other Medications and Substances for Ozempic (Semaglutide)

Ozempic can have interaction with other substances and medications and this can potentially affect the way it works or even increase the risk of side effects. It’s important to tell your doctor about any medication or supplement that you are taking before Ozempic treatment starts.
