Hello Ma'am,
Seasonal allergies are a common condition in the population for both children and adults. Fortunately, there are a variety of agents available to relieve symptoms.
Treatment is usually started with an oral antihistamine that will help control the overall symptoms. Claritin is commonly used and is safe in pregnancy. You can take 1 10 mg tablet once a day during the allergy period. For congestion, I also recommend using a saline solution such as Sinus Rinse.
For headache, Tylenol is the agent of choice in your case given your pregnancy. It can be taken at the same dose as an adult, 500 to 1000 mg 4 times a day, not to exceed 4g per day.
If you do not see improvement in your symptoms within 2 weeks with the use of Claritin, I would advise you to consult your family pharmacist who will make a treatment plan tailored to your situation.
Don't hesitate to contact us with any other questions!
Happy day,
