Etanercept, also known as Aminoterol oral solution, is generally used to stop coughing and dissolve phlegm, with a stronger effect on phlegm. Side effects are relatively rare and only occur very occasionally, for example, some people will experience mental and neurological symptoms, occasional headaches, tremors of the limbs, a preference for sleep and a feeling of restlessness, and some people will experience dizziness and insomnia. Others may experience numbness and excitement in the extremities and occasionally see palpitations or tachycardia. Elevated blood pressure and arrhythmias are less common. In some atopic patients, systemic allergy may occur, manifesting as itching and bronchospasm, hypotension, and deficiency, which should be discontinued immediately.
