Common Side Effects

Common

Injection site reactions

Mild redness, swelling, or discomfort at the injection site is one of the most frequently reported side effects of injectable peptide therapy. These reactions are typically transient and resolve within a few hours to a day.

Nausea

Gastrointestinal discomfort, including nausea, is among the most commonly reported side effects of weight management peptides, particularly GLP-1 receptor agonists. Starting at a lower dose and titrating up gradually can help minimize this effect.

Decreased appetite

While appetite reduction is often a desired effect for weight management, some patients may experience a more pronounced decrease in appetite than expected. Providers typically adjust dosing to find an optimal balance.

Gastrointestinal discomfort

Constipation, diarrhea, or abdominal discomfort can occur, especially during the early weeks of therapy. These symptoms generally improve with continued use and dietary adjustments.

Uncommon Side Effects

Uncommon

Mild headache

Some patients report mild headaches during the initial days of therapy. This is generally temporary and tends to diminish as the body adjusts to treatment.

Fatigue

Some patients report feeling tired or low in energy during the adjustment period, particularly if caloric intake decreases significantly. Adequate nutrition and hydration can help mitigate this.

Rare Side Effects

Rare

Pancreatitis risk

In rare cases, GLP-1 receptor agonists have been associated with pancreatitis. Patients should be aware of warning signs such as severe abdominal pain and seek immediate medical attention if they occur.

Gallbladder issues

Rapid weight loss associated with semaglutide therapy may increase the risk of gallstone formation. Patients with a history of gallbladder issues should discuss this with their provider.
