Especially at the beginning of the second trimester of pregnancy, many women suffer from allergy-related nasal congestion. What helps in this situation?

One reason that speaks in favor of continuing desensitization during pregnancy is the vital indication that is present, for example, in the case of a severe insect venom allergy. The risk of an anaphylactic reaction to an insect bite during pregnancy might be higher than the risk of a side effect of desensitization.
