Can you take hay fever medicine during pregnancy? The quick answer is; it depends on the medicine.

During pregnancy, you can take some hay fever medicines but not others, because there’s not enough evidence on their safety.

Get advice first

Always check with your pharmacist or GP before taking any medicine when you’re pregnant, including hay fever medicine. They will assess the medicine’s benefits against the risk of side effects and let you know if it's safe to take. They'll also look at your individual circumstances when deciding if your hay fever symptoms need to be treated with medicine.

Drug free therapy

You could try a drug free allergy reliever. Using light therapy, the reliever is suitable to use during pregnancy. The red light suppresses the cells that release histamine, helping to reduce the symptoms associated with hay fever and allergic rhinitis.
