Understanding Inherent Medication Risks (Common & Serious Side Effects)
Even when GLP-1 RAs are genuine and used exactly as prescribed, they can still cause side effects. These range from mild, temporary issues to rare emergencies that need prompt medical care. The table below lists both common and serious reactions. Managing any of them is far harder without professional supervision, especially if you are using unverified or unregulated products.
Common vs. Serious Side Effects & Recommended Actions
| Side-Effect Category | Examples | What to Do |
|---|---|---|
| Common Gastro-intestinal (GI) | Nausea, vomiting, diarrhea, constipation, belly pain, decreased appetite, belching, bloating, gas | Monitor symptoms. They are often dose-related and may fade with time. Call a clinician if severe or persistent, and keep hydrated. |
| Other Common Effects | Headache, fatigue, dizziness, mild injection-site redness, swelling, or itching | Monitor. If bothersome, contact a clinician. Rotate injection sites to reduce local reactions. |
| Serious – Severe Allergic Reaction / Anaphylaxis | Swelling of face, lips, tongue, or throat; trouble breathing or swallowing; wheeze; rapid or weak pulse; spreading rash/hives; dizziness or fainting | Call emergency services (911 or local equivalent) immediately. |
| Serious – Pancreatitis | Severe, constant upper-abdominal pain that may reach the back, with or without vomiting | Stop the medicine and seek emergency care. |

| Serious – Severe Hypoglycemia | Confusion, drowsiness, blurred vision, slurred speech, shakiness, sweating, fast heartbeat, weakness, seizures (risk rises if also on insulin or sulfonylureas) | Treat low blood sugar if awake (glucose tablets or juice). Get medical help fast. Severe cases may need glucagon. |
| Serious – Kidney-Injury Signs | Less urine, leg/ankle swelling, unusual tiredness, breathing trouble | Call a healthcare provider. |
| Serious – Severe GI Problems | Ongoing, intense nausea, vomiting, or diarrhea that leads to dehydration | Call a healthcare provider. Dehydration can harm kidneys. |
