FAQs about allergy medicines

What is the best medicine for hay fever?

There is no single best option, because it depends on your symptoms. Antihistamine tablets help with sneezing and itching, steroid nasal sprays work well for a blocked or runny nose, and eye drops target itchy eyes. Many people use a combination, and a pharmacist can suggest what fits.

What is the difference between cetirizine, loratadine, and fexofenadine?

All three are antihistamines taken once a day. Cetirizine can cause mild drowsiness in some people, while loratadine and fexofenadine are generally less likely to. Individual responses differ, so you may need to try more than one to find what suits you.

Which allergy medicine is least likely to make me drowsy?

Newer antihistamines such as loratadine and fexofenadine are usually described as non-drowsy or less sedating. Older ones such as chlorphenamine are more likely to cause sleepiness, so take care with driving or using machinery.

How long do steroid nasal sprays take to work?

They do not give instant relief. They usually work best when used regularly, and it can take several days to feel the full benefit. For seasonal allergies, many people start using them shortly before the pollen season begins.

Can I take allergy medicines during pregnancy or while breastfeeding?

Some are considered more suitable than others, but this depends on your circumstances. Always check with a pharmacist, midwife, or doctor before taking an allergy medicine in pregnancy or while breastfeeding.

When is an allergic reaction an emergency?

Call 999 straight away if someone has difficulty breathing, swelling of the face, lips, or tongue, wheezing, or sudden collapse after exposure to a possible trigger. These can be signs of anaphylaxis, which needs emergency treatment and cannot be managed with ordinary antihistamines alone.
