Types Of Injectable Medications For Weight Loss

Anyone who has attempted weight loss through conventional means and perhaps even some unconventional methods, is well acquainted with how difficult and unexpectedly challenging it can be. An individual’s capacity to lose weight can be influenced by several factors, including age, genetics, hormone imbalances, inadequate sleep, excessive stress, and more. At times, the survival nature of our bodies and metabolism can make it so challenging that we want to quit.

Fortunately, a relatively recent solution has emerged that can help break through many of the obstacles that have inhibited sincere attempts at weight loss. There are three types of weight loss injections that have been FDA approved, and today we are going to tell you about their background, usage, and potential for weight loss.

What Is The History Of Prescription Weight Loss Injections?

The weight loss injections currently available on the market were initially developed for dealing with type 2 diabetes. Patients who took these medications to manage their blood glucose levels were surprised to experience weight loss as a beneficial side effect. Many individuals found that losing weight greatly improved, and in some instances, completely resolved, their weight-related health problems.

Currently, there are three weight loss injections that have been approved by the FDA: Saxenda, Wegovy, and Zepbound.

How Do These Injections Help People Lose Weight?

When we eat, our bodies produce hormones called glucagon-like peptide-1 that help with digestion. These hormones regulate the production and release of insulin and glucagon, which together keep our blood sugar levels balanced. These hormones not only regulate our metabolism but also send signals to our brains to let us know if we are hungry or full.

Weight loss injections imitate these natural hormones and help keep your metabolism working at its best, so they are called glucagon-like peptide-1 agonists. They reduce blood sugar and curb appetite, helping you burn more calories, eat less, and lose weight.

What Are The Different Weight Loss Injections Available Today?

Currently, there are three different weight loss injections that have been FDA-approved. Following are the different medications and the brand names of weight loss injections:

Liraglutide (Saxenda)
Initially FDA-approved in 2010 for treating type 2 diabetes, liraglutide was marketed as Victoza, but in 2017, it became the first prescription injection (GLP-1 receptor agonist) to be approved by the FDA for treating obesity under the brand name Saxenda. It is administered through daily injections using a prefilled injector that requires a new needle every day. Although it has been around the longest, it never became popular due to the inconvenience of administering daily shots and the underwhelming weight loss results.
Semaglutide (Wegovy)
Semaglutide has been distributed under the brand name Ozempic since 2017, when it was approved by the FDA as a treatment for type 2 diabetes. The FDA approved it for obesity treatment in June 2021 under the name Wegovy, and it comes preloaded into a one-time-use injector pen. The injections are given once weekly and work best if they are done on the same day of the week and at the same time.

Weight loss results released from clinical trials were significantly better than those of Saxenda, and as soon as it was released, Wegovy became instantly popular. The manufacturer is still having issues keeping up with the demand.

Tirzepatide (Zepbound)
The most recent addition to the other weight loss injections names is Zepbound, which was approved for obesity treatment in November 2023. After being on the market since May 2022 as Mounjaro, tirzepatide showed better results in providing help with blood sugar regulation than both liraglutide and semaglutide.Zepbound is different from the other types of prescription injections because it not only mimics GLP-1 hormones but also GIP hormones. The combination of these two copycat hormones working together has been shown to deliver the most significant weight loss results to date, and some say that Zepbound is the best weight loss injection available today.

Where Do You Give Yourself Weight Loss Injections?

Prescription injections to treat obesity should be done in an area of the body where fatty tissue is present, such as the outside of the upper arm, the abdomen (stomach), or the outer thigh. The site you choose to administer your injection should be rotated every week so one specific place does not become overly irritated or tender. Care must be taken as the medication should never be injected into a muscle or a vein.

The medication will work best if the injections are administered on the same day each week and at approximately the same time. It is also very important to follow the dose instructions from your doctor, which can vary depending on the type of weight loss injections you have been prescribed.

Administration and Dosing

Nausea and vomiting are common side effects that most people experience when they first begin using these different weight loss injections. It is normal for your body to need a little time to become accustomed to these injections, and so to help avoid serious discomfort, the doctor will start you on the lowest dose available and then increase it every month until you are able to tolerate the highest approved dose, which normally takes between five and six months. The chart below will give you a comparison of these different prescription weight loss injections:

*For use in treating overweight and obesity.

**Reported during clinical trials. The weight loss percentages shown on the chart are only averages, and many individuals have exceeded these weight loss numbers.

How Should Prescription Weight Loss Injections Be Used?

Weight loss injections should be viewed as temporary tools to help you tackle both old and new challenges that arise as you navigate your weight loss journey, and you cannot rely on them to do all the work for you. You need to avoid previous behaviors that contributed to your weight gain and form new, healthier lifestyle habits.

Many individuals do not understand how their body responds to their weight loss efforts or underlying things that can thwart their best efforts. These different injections for weight loss can help break through some of these inhibitors and help you finally see some results. When used in conjunction with your weight loss program or a non-surgical weight loss procedure, these injections can help you lose a substantial amount of weight.
