How to Safely Take Antihistamines

Antihistamines are the drug of choice to treat allergy symptoms. Most are safe and available without prescription. Follow a few guidelines to ensure the fewest side effects.

Instructions

Difficulty: Moderately Easy

1. Talk to your pharmacist. They have lots of information on all kinds of medications.
2. Read the package label and follow directions carefully.
3. Understand that antihistamines offer some relief, but do not cure allergies.
4. Take an antihistamine ahead of time for maximum benefit. For example, if you are planning an outdoor picnic and the pollen count is high, take the medicine an hour before you plan to be outdoors.
5. Take the minimal dose necessary to counteract symptoms.
6. Buy a single antihistamine drug, not a combination product.
7. Avoid antihistamines if you are pregnant or lactating, or have glaucoma, enlarged prostate or chronic respiratory disease. Do not give antihistamines to children under 12.
8. Take antihistamines with plenty of water.
9. Swallow each pill whole, especially time-released tablets. Don't divide or chew them.
