Which online weight loss injections are FDA approved?

Wegovy is semaglutide, given as a once-weekly injection or a once-daily tablet, and is approved for weight management [1]. Saxenda is a once-daily liraglutide injection approved for weight management [2]. Generic liraglutide is also FDA approved for weight management [2]. Zepbound is a tirzepatide injection; its label classes tirzepatide as a GIP and GLP-1 receptor agonist, not a pure GLP-1 drug [3].

Foundayo is orforglipron, a once-daily tablet approved for weight management [4]. Wegovy tablets are the other approved tablet [1]. Ozempic, Rybelsus, Victoza, Trulicity, Byetta, Mounjaro and Soliqua have diabetes indications rather than FDA weight-management indications [6][7][8][9][10][11][12].

How should you compare total cost?

Compare the exact product, dose and supply period, not a headline monthly figure. Two label facts make this matter:

• Dose changes over time. The Wegovy label starts at 0.25 mg once weekly and steps up every 4 weeks to a maintenance dose of 1.7 mg or 2.4 mg, with 2.4 mg recommended [1]. A price quoted for one dose strength may not be the price at the dose taken later in treatment.
• Dosing frequency differs. Wegovy and Zepbound are once-weekly injections, while Saxenda and generic liraglutide are once-daily injections [1][2][3]. Compare the same length of supply across products.

Wegovy tablets and Foundayo are separate, non-injection options, so they do not answer which injection is cheapest [1][4]. Wegovy and Saxenda are different drugs, and Zepbound is tirzepatide, so the products are not interchangeable by name [1][2][3].

What warning signs should you check before buying?

FDA lists these red flags for telehealth sellers of compounded GLP-1 drugs:

• a claim that the compounded drug is the same as an FDA-approved drug
• prices that seem too good to be true
• medicine that looks different from what was pictured, or arrives broken or without instructions
• no screening and prescription by a licensed doctor before the medicine is provided
• no licensed doctor available to answer questions after purchase
• label spelling errors, wrong pharmacy addresses, or a pharmacy name that may be fraudulent [5]

What about compounded semaglutide and tirzepatide?

Compounded drugs are not FDA approved, and FDA does not review them for safety, effectiveness or quality before they are marketed [5]. FDA says compounded drugs should only be used in patients whose medical needs cannot be met by an FDA-approved drug [5]. It also recommends a prescription from a doctor and filling at a state-licensed pharmacy [5].

Retatrutide and cagrilintide are not FDA approved, cannot be used in compounding under federal law, and have not been found safe and effective for any condition [5]. FDA also says multi-dose vials of compounded GLP-1 drugs should be discarded 28 days after first use, even if medicine remains, and that a new sterile needle and syringe should be used for each dose [5]. FDA recommends not using an injectable GLP-1 drug that arrives warm or without adequate refrigeration [5].
