This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
I read post #29 twice before replying, because I had assumed the opposite.
Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.
The correction was fair and I had been repeating something I had not checked carefully enough.
This follows post #29 rather than contradicting it.
Acute kidney injury: rare but reported. Symptoms (decreased urine output, creatinine elevation) warrant urgent evaluation. Severe dehydration during weight loss is a risk factor.
Severe gastrointestinal events: persistent vomiting, abdominal pain out of proportion, or signs of bowel obstruction warrant urgent evaluation. Mild nausea and constipation are ordinary; severe versions are not.
Allergic reactions: true allergy (anaphylaxis, severe rash) is rare with these peptide compounds but possible. Distinguishing true allergy from GI intolerance matters.
Psychological adverse events: mood changes, anxiety, or suicidal ideation warrant discussion with a mental health professional. These are rare but real.
For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.
Medullary thyroid carcinoma is the reason these compounds are contraindicated in people with personal or family history of MTC or multiple endocrine neoplasia type 2. Rodent toxicology showed a signal; human evidence of causation is absent but caution is appropriate.
Pancreatitis is a genuine serious adverse event to know: severe epigastric pain, back pain, elevated lipase (≥3× upper limit of normal). If this constellation appears, stopping the drug and seeking urgent evaluation is appropriate.
Picking up post #38: that is the part I would want checked first.

I disagree with the reply above, and I think the disagreement is substantive rather than terminological.
The distinction being drawn does not survive when you look at the published data for this specific question. I would be glad to be shown wrong on this, because the version I am arguing against is more convenient.
Where to report: in many countries there is a pharmacovigilance system where adverse events can be reported. FDA MedWatch in the US, Yellow Card in UK, EudraVigilance in EU.
Reporting to regulatory agencies: if you have had a serious event, reporting it to the regulatory agency in your country can help with signal detection across the population.
Worth separating two things that post #44 runs together.
Serious and unexpected events are the ones to document and report. Serious means hospitalization-level serious. Unexpected means not in the drug's known profile. Both together warrant official reporting.
How to document: date, exact symptom or event, severity, duration, outcome, any medical attention sought. Detailed documentation is far more useful than a vague report.

Two things before anyone answers the substance.
First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.
post #51 answers the question as asked. The question underneath it is different.
Acute kidney injury: rare but reported. Symptoms (decreased urine output, creatinine elevation) warrant urgent evaluation. Severe dehydration during weight loss is a risk factor.
Allergic reactions: true allergy (anaphylaxis, severe rash) is rare with these peptide compounds but possible. Distinguishing true allergy from GI intolerance matters.
