Ventolin solution for infusion contains the active ingredient salbutamol, which is a type of medicine known as a short-acting beta 2 agonist. (NB. Salbutamol is also available without a brand name, ie as the generic medicine.)
Ventolin infusion is given as a drip into a vein (intravenous infusion) to treat two very different conditions. Firstly, salbutamol infusion may be given in hospital to treat severe narrowing of the airways that is causing difficulty breathing (bronchospasm). This might be due to a severe asthma attack, chronic obstructive pulmonary disease (COPD, eg emphysema and chronic bronchitis), or a severe allergic reaction. Secondly, salbutamol infusion can be used to help stop premature labour.
Salbutamol works by acting on receptors called beta 2 receptors. These are found in the lungs and the uterus (womb).
When salbutamol stimulates the beta 2 receptors in the lungs, it causes the muscles in the airways to relax. This allows the airways to open and so makes it easier to breathe.
When salbutamol stimulates the beta 2 receptors in the uterus, it causes the muscles in the walls of the uterus to relax. This can stop the contractions associated with premature labour. Salbutamol infusion can be used to stop labour that starts between 24 and 33 weeks gestation. It usually delays delivery by at least 48 hours. This can give sufficient time to treat the mother with corticosteroids, or take other measures to improve the outcome for mother and baby, including moving the mother to a hospital with a neonatal intensive care unit.
This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy.If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.

Because a side effect is stated here, it does not mean that all people using this medicine will experience that or any side effect.

This medicine should not be used with beta-blockers, such as atenolol, propranolol or timolol. This is because beta-blockers have an opposite action to this medicine and cause the airways to narrow. This can result in breathing difficulties for people with asthma or COPD. This problem has sometimes been seen with eye drops containing beta-blockers, eg used for glaucoma.
Salbutamol can potentially cause a serious decrease in the levels of potassium in the blood (hypokalaemia), which may result in adverse effects. This effect can be increased by the following medicines, which can also lower potassium in the blood:
This is why people with severe asthma or COPD, who may be taking several of these medicines, should have their blood potassium levels monitored regularly.
