A pregnant lady with allergic rhinitis, worse in the morning, with red itchy eyes and nasal congestion. Which would be the most appropriate treatment?

• A. Loratadine
• B. Pseudoephedrine
• C. Intranasal corticosteroids
• D. Sodium cromoglicate

Answer: (D)

Focus on safety in pregnancy while still aiming to control allergic rhinitis. The safest options are those with minimal systemic absorption and well-established safety data for use during pregnancy. Sodium cromoglicate is a mast cell stabilizer that works locally in the nasal mucosa, preventing mast cells from releasing histamine and other mediators that drive nasal symptoms. Because it is largely non-systemic, it has a very favorable safety profile in pregnancy compared with agents that have systemic absorption. This makes it a sensible first-line choice when relief is needed with the least fetal risk. It can be used regularly to prevent symptoms, which is helpful for morning symptoms. While it may be less immediately potent than intranasal corticosteroids for some patients, its safety advantage in pregnancy can make it the most appropriate option in a situation where safety is a primary concern. Pseudoephredrine is a decongestant and is typically avoided or used with caution in pregnancy due to potential fetal effects. A modern intranasal corticosteroid is effective and widely used in pregnancy, but it has some systemic absorption and, although generally considered safe, does not carry the same absolute local-safety advantage as cromoglicate. Loratadine is an option and is generally considered safe in pregnancy as well, but when prioritizing the safest option with minimal systemic exposure, sodium cromoglicate stands out.
