Side effects can start early, but timing varies
Some people notice nausea or fullness soon after the first dose. Others feel little at first and develop symptoms after dose escalation. Timing depends on dose, meal size, fat intake, hydration, constipation, and individual sensitivity.
| Point | What to check | Why it matters |
|---|---|---|
| first dose | Timing, severity, dose, meals, hydration | Prevents judging from one factor only |
| dose escalation | Symptoms and lifestyle pattern | Many problems are amplified by under-eating or dehydration |
| timing | Other medicines and medical history | Some cases require medical review |
After starting and after increasing dose
The first week after a new dose is a common period to monitor. If symptoms are mild and improving, practical food and fluid adjustments may be enough. If symptoms are severe or worsening, clinician input is needed.
Track timing, not just intensity
Write down dose day, symptom day, meals, fluids, bowel movements, and exercise. This often reveals patterns that are invisible from memory alone.
