Q: Question: A 27-year-old woman, pregnant for 10 weeks and with persistent severe allergic asthma. Currently, it is adequately controlled with daily inhaled budesonide and inhaled salbutamol at the request of rescue. Go to your consultation concerned about the possible teratogenic effects of your antiasthmatic medication. Which of the following would be the correct attitude?
Options: <1> Since asthma improves during pregnancy in most patients, it is best for the patient and the fetus to discontinue anti-asthmatic treatment. <2> Suspend budesonide because it has been linked to an increased risk of fetal malformations and replace it with an oral antileukotriene (montelukast). <3> Remove the current treatment and replace it with oral prednisone at the lowest possible dose. <4> Maintain the current treatment and reassure the patient about its side effects and the need for adequate control of asthma during pregnancy. <5> Replace budesonide with an anti-IgE monoclonal antibody (omalizumab) for its greater safety in pregnancy as it is not a drug.
