Weight Loss Medications Containing Semaglutide

different semaglutide medications

Weight loss medications have been taking the world by storm thanks to their efficacy and remarkable results. Semaglutide, originally designed to treat type II diabetes, has gained widespread attention for its impressive weight loss benefits.

While Ozempic has become almost synonymous with semaglutide, there are actually three semaglutide brands available: Ozempic, Wegovy, and Rybelsus. All three are manufactured by Novo Nordisk, a leading pharmaceutical company.

Ozempic, Wegovy, and Rybelsus may share the same active ingredient, but their specific applications and benefits can vary.

Different Semaglutide Medications

Semaglutide is a GLP-1 receptor agonist, which mimics the naturally occurring GLP-1 hormone in the body. Thanks to its mechanism of action, semaglutide medication keeps you fuller longer and helps to regulate blood sugar levels by stimulating insulin release and inhibiting the release of glucagon.

Semaglutide comes in oral tablets (Rybelsus) and as a subcutaneous injection (Ozempic, Wegovy).

Ozempic

Ozempic is easily the most well-known semaglutide medication. This semaglutide drug is injected once weekly.

Ozempic is FDA-approved for diabetes management.

The initial dose of Ozempic is 0.25 mg. The dose is then increased every four weeks until you reach the maximum dosage of 2.0 mg.

Wegovy

Like Ozempic, Wegovy is a once-weekly injectable semaglutide medication. Unlike Ozempic, Wegovy is FDA-approved for weight loss.

Ozempic and Wegovy are essentially the same, except for three differences:

  1. The FDA approval. Ozempic may be prescribed off-label for weight loss by individual doctors, but Wegovy is actually FDA-approved for weight loss.
  2. The dosage. Both begin with an initial dose of 0.25 mg. It is their maximum dose that differs. Ozempic maxes out at 2 mg, while Wegovy goes up to 2.4 mg.
  3. The injector pen. Ozempic comes with multiple doses in a single pen. Wegovy, on the other hand, comes in a single dose injector pen.

Rybelsus

Rybelsus is an oral medication for type-2 diabetes that is taken once daily. It comes in three doses: 3 mg, 7 mg, and 14 mg. Though they are much higher than what is available for Ozempic and Wegovy, these are considered equivalent with the injected doses.

Comparing Semaglutide Weight Loss Medications

There are no head‑to‑head clinical trials that directly compare Wegovy, Ozempic, and Rybelsus in patients using the same dosing protocols or trial populations—each product has been evaluated in its own separate clinical programs (e.g. STEP, SUSTAIN, PIONEER) and therefore any comparison between them relies on indirect evidence or network meta‑analyses, not randomized, controlled data. One such network meta‑analysis found that oral semaglutide (Rybelsus 14 mg) offered similar HbA₁c reductions but slightly less weight loss than injectable doses of semaglutide, without statistically significant differences when compared to the 1 mg weekly formulations—but still did not include any direct Ozempic vs Wegovy comparisons in the same trial.

Wegovy is the semaglutide formulation specifically approved for weight loss. Ozempic and Rybelsus are approved for blood sugar control (diabetes), though they may result in modest weight reduction. Only Wegovy has been studied head-to-head with placebo and lifestyle interventions for weight management—there are no trials directly comparing its effectiveness against Ozempic or Rybelsus.

Semaglutide Medication Effectiveness

Ozempic and Wegovy are particularly effective, with individuals losing an average 15-20% of their starting weight in clinical trials. It is difficult to determine which is more effective, but a review of studies found that the 2.4 mg max dose (only available with Wegovy) shows more promising weight loss than the lower doses.

Rybelsus does not appear to be as effective as the injectable semaglutide medication in clinical trials. Studies have shown that the lowest dose (3 mg) of Rybelsus results in about 5 pounds of weight loss over 6 months. Another study showed the highest dose (14 mg) showed less than 5% loss over 12 months.

Higher doses of 25 mg and 50 mg are currently being studied for their weight loss potential. The 50 mg doses showed a 15% loss over 68 weeks.

Semaglutide Medication Safety

Semaglutide is not considered a risky medication for most individuals. It does, however, come with some potential side effects. The side effects for these medications are the same thanks to their shared active ingredient.

Most commonly, individuals taking a semaglutide medication will deal with gastrointestinal distress:

  • Diarrhea
  • Constipation
  • Stomach pain
  • Loss of appetite

There are some more serious side effects that can occur, so you should be aware of what to watch out for.

It should be noted that Ozempic and Wegovy also include injection site irritation as a potential side effect.

Semaglutide Cost

It is unlikely that your insurance plan will cover off-label medication use. Many plans will not cover weight loss prevention or treatment even if the medication is FDA-approved for weight loss. So, unfortunately, you will likely be paying out of pocket for your semaglutide medication.

The average monthly costs for these medications are:

Manufacturer coupons and savings cards can help to offset the costs. There are also subscription options available.
