I'm taking 1200mg of epilim a day is it safe to take both paracetamol and ibuprofen together for pain when on this medication?

Yes. It is always better to take the least amount of pain medicine possible but there are no drug interactions among these three medications.
Should be fine. To take Epilim with paracetamol or ibuprofen. Be sure to check with prescribing doctor. Be well.
It Should be OK. Ro take normal amounts of Paracetamol and IBuprofen with Epilium, which if Sodium valporate, an antiepileptic drug. Since Paracetamol (acetaminophen) and Sod valporate are both excreted by liver, I would be careful in watching its liver side effects by monitoring liver function tests on a regular basis.
