# Less-drowsy antihistamines

Compare allergy medicines by active ingredient and leaflet instructions.

**What you need to know**

Less-drowsy antihistamines are used for allergy symptoms, but drowsiness can still occur. Different medicines and strengths have different age limits, directions and cautions. A pharmacist can help you choose a suitable option.

This is an educational guide. Sanara is not taking orders or preorders. Compare the actual product’s label, suitability and total cost before buying from a retailer.

What to check before buying

## Check the label

- Active ingredient and strength
- Age limits and dosing leaflet
- Driving, alcohol and interaction warnings

## Directions and pack size

Use only as directed on the finished product’s label or patient information leaflet. Sanara has not verified a specific pack, dose schedule or supply duration for this guide.

## Safety

Read the patient information leaflet. Not suitable for everyone — check with a pharmacist if you take other medicines.
