Asthma & Pregnancy
Most women with asthma do tend to have normal pregnancies however during pregnancy, asthma control oftens changes, presumably related to hormonal influences, though it is unpredictable. Many women’s asthmas control improves in pregnancy, whilst other get significantly worse. In general, one third gets better, one third gets worse and the other third stay the same during pregnancy.
However, Asthma management is crucial during pregnancy as most symptoms can vary. It can increase the risk of complications for both the mother (like preeclampsia) and the baby (such as premature birth or low birth weight). Women should consult their doctor, asthma nurse, and midwife as soon as they know they are pregnant to create a management plan and continue their prescribed medications.
Asthma Treatments & Pregnancy
The good news is asthma treatments during pregnancy are safe yet essential. It is vital to continue using your prescribed preventer and reliever inhalers, along with medications like Montelukast or oral steroids for exacerbations, this protects the mother and the baby from the risks of poorly controlled asthma, which include low birth weight.
Additionally, managing asthma during pregnancy involves avoiding known triggers, preventing hay fever, stopping smoking & staying active to maintain a good health.
Below are the key asthma medications
- Preventer Inhalers: Inhaled corticosteroids are essential for controlling airway inflammation and should be taken exactly as prescribed.
- Reliever Inhalers: Short-acting beta-agonists (SABAs) can be safely used when needed to relieve asthma symptoms.
- MART and AIR Inhalers: Combined maintenance and reliever inhalers, or single inhaler reliever therapies, are considered safe options.
- Montelukast (Leukotriene Receptor Antagonists): Continuing montelukast is safe during pregnancy.
- Theophylline: Safe at recommended doses, but serum levels should be monitored as pregnancy can alter how the body processes the drug
- Oral Steroids: Short courses of oral corticosteroids (such as prednisolone) are safe for managing asthma flare-ups, with benefits that outweigh potential risks.
Please note: Asthma inhalers, relievers or preventers are safe to use as normal during breast feeding.
Montelukast can be used if needed. There is limited research but amount in breastmilk appears significantly lower than that licensed to be given to a 6-month-old baby.
Prednisolone 40mg for 5 days is unlikely to affect the baby and breastfeeding can continue as normal.
Managing your asthma before & during pregnancy
To help manage your asthma during pregnancy, involves consulting a doctor for an early asthma review, continuing prescribed medication such as inhaled corticosteroids (like budesonide) and bronchodilators, avoiding triggers, maintaining a healthy lifestyle, and using a written asthma action plan. Regular monitoring, including potential spirometry and ultrasounds, helps ensure good control for both the mother and the baby.
