I have influenza, and is causing me some severe muscle cramps. I have taken 2 800mg ibuprofen today, can I have another? I took the first ibuprofen at 4.30 am and the second around 11 am Now I'm 6.30pm and muscle cramps and headaches are getting worse.
We do not recommend taking large doses of ibuprofen - doses over 800mg. Please follow the instructions on the box or bottle on the hours between doses depending on age and weight, check that there are no contraindications. You should avoid taking aspirin.
