Asthma during pregnancy should be well-controlled to keep both mother and baby safe.
Reliever inhalers containing Salbutamol (commonly known in the UK as Ventolin or the Blue inhaler) are generally safe to use in pregnancy and are often recommended as first-line treatment.
Do not stop your asthma medication without consulting a doctor, as poorly controlled asthma can increase the risk of low birth weight or preterm birth.
Salbutamol (same as Albuterol) has a strong safety record and is widely used in pregnant women.
This guide covers what you need to know about using Salbutamol in pregnancy and explores other available treatment options.
What is Salbutamol?
Salbutamol (Ventolin) is a rescue medication for acute exacerbations of asthma. It's part of the short-acting beta-agonists (SABAs) group. It relaxes lung muscles, making breathing easier; it is handy for people with asthma and COPD.

Using Salbutamol During Pregnancy:
Will I need more Salbutamol than normal during pregnancy?
If you’re pregnant and have a history of asthma, you may wonder how pregnancy might affect your symptoms. In short, it depends on the person.
According to the Asthma and Allergy Foundation of America, 1 in 3 women who are pregnant and have asthma will see their symptoms improve during pregnancy. And about 1 in 3 women who are pregnant and have asthma will see their symptoms worsen. The remaining women will experience no changes in their symptoms.
As the statistics show, there’s no consistent trend for how pregnancy affects asthma symptoms. Ultimately, the need to use more or less medication than normal depends on how your symptoms change during pregnancy.
How Much Salbutamol Can I Take During Pregnancy?
When you're short of breath, you can take 2 puffs every 4 to 6 hours. This lines up with how long the medication takes to work in your body. Pregnant women don't have different dosage recommendations compared to others. The usual dose is ‘100–200 micrograms, to be taken when required for symptomatic relief, review prevention medication if salbutamol usage is 3 or more days per week, or if nocturnal symptoms occur’.
