Naproxen side effects
Get immediate medical help if you experience an allergic reaction to Naproxen. Symptoms of an allergic reaction include: rash (itchy, red, swollen blistered or peeling skin), wheezing, swelling/itching of the face/tongue/throat, severe dizziness, difficulty breathing.
General side effects include:
- Nausea (feeling sick)
- Upset stomach
It is advised to use medications for acute migraine with moderation as they might cause side effects such as nausea, vomiting, rebound headaches and progression to chronic headache disorders. Often, anti-nausea and other symptom-preventing medications are given alongside the migraine medication to prevent such side effects. If any of these symptoms persist or cause distress, talk to your doctor.
Serious side effects
- Easy bruising/bleeding
- Difficult swallowing
- Severe indigestion, heartburn, stomach pain, nausea, vomiting or diarrhea (may be signs of an ulcer or inflammation in the stomach or gut)
- Hearing changes (ringing in the ears)
- Kidney problems (change in the amount of urine, or blood in your pee)

- Fainting, chest pain, breathlessness (may be signs of anaemia)
- Yellowish skin or the white of your eyes turn yellow (signs of jaundice or inflammation of the liver)

- Vomiting blood or blood in your faeces (poo) (signs of bleeding and perforation of the stomach or gut)
