Codeine is absolutely not found OTC in the USA...we're left with Sodium Naproxen (Aleve....another nsaid), Ibuprofen and Acetaminophen.
Because nsaids and APAP do work so different (both effect and side-effect) they can be taken together for really bad pain (but again, if it's that bad that you need to keep up a daily 2.4G Ibuprofen and 4G Acetaminophen regimen, see a doctor). Staying at or below the recommended dosage with acetaminophen is safe and can be sustained with healthy liver function for >12 years. Ibuprofen really doesn't do DAMAGE until you sustain a little more than double the recommended dose. If not taken with food (you'll get fat trying to keep up with your Ibuprofen intake), it may cause irritation or discomfort.
Regarding HeadOn, it's main active ingredient is potassium dichromate, which is used in film developing and should, under no condtion, come in contact with the skin. That's the burn.
EDIT: masterofpuppets, I really don't know if I can keep that opiod separation guide up.....thinking about it
