Infantile haemangiomas are the most common benign tumour of infancy. However the majority are selfresolving and only a small minority of cases require treatment, with various different medications being used in the past. Over the last few years, propranolol, a non-selective β-blocker, has become a popular and successful treatment for infantile haemangiomas. However, further research on its safety is needed if it is going to be used more frequently. This article summarises the current literature on propranolol for haemangioma treatment with emphasis on its toxicity and adverse event profi le.

Intravenous salbutamol is commonly used to treat children with severe asthma unresponsive to inhaled β2-agonist therapy. However, in this setting, there is little clinical trial data demonstrating its effectiveness. Additionally, there are significant concerns that intravenous salbutamol-dosing recommendations for children with acute asthma are excessive, and unnecessarily raise the potential for adverse reactions, such as lactic acidosis and tachycardia which, by increasing respiratory workload, exacerbate respiratory failure. Here, we review salbutamol clinical pharmacology and toxicology, evidence relating to its use in acute asthma and highlight gaps in the evidence base.
