Can naproxen and cocodomal make you feel sick?

Yes, both naproxen and cocodamol (a combination of codeine and paracetamol) can cause nausea and other gastrointestinal issues as side effects. Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), may irritate the stomach lining, while cocodamol can lead to constipation and dizziness. If you experience persistent sickness after taking these medications, it's advisable to consult a healthcare professional.
