Welcome to Bluelight Zacho.
7 Panadine Forte (Paracetamol 500mg & Codeine Phosphate 30mg) & 5 Nurofen Plus (200mg of ibuprofen and 12.8mg of Codeine Phosphate) ?
So if I am right that is 3.5 grams APAP, 1 gram Ibuprofen and 274 mg of codeine? I would not think that you would come to much harm from the paracetamol or ibuprofen as they are both within (UK, do not know about Australia) daily recommended limits, but if you are opiate naive 274mg of codeine is a fair amount. I cannot see you coming to much harm from this as a one off, but to repeat this regularly may flirt with codeine dependency and using those doses of the other drugs day in and out will not do your insides any favours in the long run. If it is the codeine that you are interested in, there is a simple procedure used to separate codeine phosphate from combination drugs known as a cold water extraction, there are plenty of threads around Bluelight on how to perform this so why not give our search engine a whirl if you wish to have a look.
Please be careful.
