Side effects include swelling/redness/itching at the injection site, tiredness, nausea, vomiting, diarrhea, or constipation can occur. Nausea usually lessens as you continue to use semaglutide. If any of these effects last or get worse, tell your doctor or pharmacist promptly. An allergic reaction is rare but get medical help immediately if you notice rash, itching, swelling (especially of the face/tongue/throat), severe dizziness or trouble breathing. The risk of serious side effects increases in patients with hypoglycemia, kidney problems, and risk of allergic reactions. Note: The 1mg/mL of Cyanocobalamin added to reduce nausea side effects. This is not a complete list of side effects, contact your doctor or pharmacist if you experience any abnormal effects of this medication. Note: There is a risk of Thyroid C−Cell tumors. If you or any family members have been diagnosed with Multiple Endocrine Neoplasia Syndrome Type 2 or Medullary thyroid cancer you should not take Semaglutide. If you have ever had pancreatitis consult with your medical provider as using Semaglutide can increase the risk of developing pancreatitis.
