Clenbuterol may cause side effects such as sweating (mainly neck region), muscle tremor, tachycardia, slight hypotension or restlessness. These are typical for β-agonists and occur rarely.
Ventipulmin antagonises the effects of prostaglandin F2α and oxytocin.
Ventipulmin is antagonised by β-adrenergic blocking agents.
If used during pregnancy, treatment must be discontinued at the expected time of delivery since uterine contractions may be abolished under its influence.
Dosages of clenbuterol hydrochloride up to 4 times the therapeutic dose (administered orally) for a period of 90 days caused transient side effects typical for beta2-adrenoceptor agonists (sweating, tachycardia, muscle tremor), which required no treatment. In case of accidental overdose, a β-blocker (such as propranolol) may be used as antidote.
