Paracetamol (acetaminophen) with caffeine is a combination medicine indicated for the temporary relief of pain and discomfort associated with a number of conditions such as headache or muscle pain. Paracetamol has a narrow safety margin and there are number of risks associated with paracetamol. It is only safe and effective when used according to directions on OTC (Over-The-Counter) and Rx labelling. However, long-term use of paracetamol increases the risk of kidney and liver failure and makes people more vulnerable to high blood pressure and strokes. Chronic or excessive administration of caffeine has been implicated in a range of dysfunctions involving the liver, renal system, gastrointestinal system, and musculature. A patient taking the combination of paracetamol with caffeine may be more likely to experience adverse effects than to get improved analgesia, compared with paracetamol alone.
