GLP-1 Medication Safety: What You Need to Know

GLP-1 medications have a well-documented safety profile, but they carry real risks and are absolutely not for everyone. This page outlines the critical contraindications, precautions, and emergency symptoms you must discuss with a healthcare provider before considering treatment.

Absolute Contraindications

Under no circumstances should you take GLP-1 medications if you fall into the following categories:

Medullary Thyroid Carcinoma

Do not use if you or any family members have a history of MTC.

Multiple Endocrine Neoplasia (MEN) 2

Do not use if you have MEN 2 syndrome.

Pregnancy and Breastfeeding

GLP-1s are not recommended. You must discontinue use well before attempting to become pregnant.

Known Hypersensitivity

A prior severe allergic reaction to semaglutide, tirzepatide, or any of their ingredients.

Precautions to Discuss With Your Provider

Honest medical history disclosure is critical. You must tell your provider if you have a history of:

  • Pancreatitis (inflammation of the pancreas)
  • Gallbladder disease or gallstones
  • Kidney issues or reduced kidney function
  • Diabetic retinopathy (vision problems related to diabetes)
  • Elevated resting heart rate or heart conditions

Drug Interactions

Because GLP-1 medications slow stomach emptying, they can affect how your body absorbs oral medications. You must disclose all medications, supplements, and vitamins you currently take to your provider to avoid dangerous interactions.

What "Not FDA-Approved" Means

While FDA-approved brands (like Wegovy and Zepbound) undergo rigorous safety evaluations, compounded medications do not. Compounded GLP-1s lack FDA review for safety, efficacy, and consistency. Providers prescribe them during shortages, but you must understand they are legally distinct from FDA-approved brands.

Emergency Symptoms

Seek emergency medical care or call 911 immediately if you experience:

  • Severe, persistent abdominal pain (with or without vomiting) that may radiate to your back.
  • Swelling of your face, lips, tongue, or throat, or severe difficulty breathing (anaphylaxis).
  • A lump or swelling in your neck, hoarseness, or trouble swallowing.
  • Yellowing of your skin or eyes (jaundice).
  • Sudden changes in your vision.

RESEARCH & REFERENCES
  • Once-Weekly Semaglutide in Adults with Overweight or Obesity

    John P. H. Wilding, Rachel L. Batterham, Salvatore Calanna, et al.; STEP 1 Study Group · New England Journal of Medicine · 2021

    Research published in the New England Journal of Medicine reported greater mean weight reduction with semaglutide plus lifestyle intervention than with placebo in the studied population. This was not a study of Sarasota Trim Clinic or compounded medication, and individual results vary.

  • Tirzepatide Once Weekly for the Treatment of Obesity

    Ania M. Jastreboff, Louis J. Aronne, Nadia N. Ahmad, et al.; SURMOUNT-1 Investigators · New England Journal of Medicine · 2022

    Research published in the New England Journal of Medicine reported weight reduction across the tirzepatide groups during a 72-week trial with lifestyle intervention. Results depended on the trial regimen and population, do not establish compounded-product equivalence, and are not a clinic outcome or a guarantee.
