What Clinical Research Shows (Side Effects)

A 2024 systematic review published via Cambridge University Press found:

• Nausea is the most common non-serious side effect
• Relative risk: 2.72 vs placebo
• Based on 23 randomized clinical trials

Study:
“The risks of adverse events with venlafaxine for adults with major depressive disorder”
Source: Cambridge University Press

👉 Key insight:
Nausea consistently appears as the most common early side effect in high-quality clinical evidence — which aligns closely with real user reports.

However, clinical trials mainly capture short-term safety, not the full lived experience over months or years.
