What is a reported adverse effect of paracetamol?

Paracetamol, also known as acetaminophen, is widely used for pain relief and fever reduction. One of the commonly reported adverse effects of paracetamol is nausea. This side effect can be attributed to its effect on the gastrointestinal system, and while it is generally well-tolerated, some individuals may experience discomfort or nausea, particularly if the medication is taken on an empty stomach or in higher-than-recommended dosages.

The other options, while they may be associated with various medications or conditions, are not typical adverse effects of paracetamol. Asthma attacks can be triggered by other medications, particularly non-steroidal anti-inflammatory drugs (NSAIDs) in susceptible populations. Rash can occur with some medications as an allergic reaction, but it is not a common side effect of paracetamol. Heart palpitations are generally associated with stimulatory drugs or conditions affecting heart rhythm, rather than paracetamol use.
