Thanks for your query.
You have not mentioned your problems, for which the said medicines have been prescribed. You are apparently a case of allergic rhinitis
or allergic asthma
Allergic conditions have no cure. You will continue to have problems, so long as you remain exposed to the causative allergens. The prescribed medicines simply curb the allergic symptoms and NOT cure the disease.
Some of these medicines, particularly budamate, will be harmful to the baby.
Therefore, do consult your treating doctor whenever you get pregnant. He will modify the prescription and give those drugs which are relatively safe in pregnancy
