How to Read an OTC Drug Label: A Quick Guide for Consumers

August 9, 2025

When you pick up an over-the-counter medication, you need to understand how to read the label on the bottle. Far from being purely cosmetic, these labels contain information from the FDA to help consumers make informed decisions about their health. The active ingredients, uses, warnings, directions, and other essential information can help you use the medication appropriately and avoid potentially dangerous mistakes.

Why Is Reading the Drug Facts Label Important?

According to the Maryland Board of Pharmacy, preventable medication errors account for approximately 7,000 to 9,000 deaths annually in the United States. When you read the label to understand what you are taking, how much to take, and what potential side effects you need to look out for, you can avoid harmful drug interactions and ensure that you effectively address your specific health concern.

How Do I Identify Active Ingredients in Medications?

The active ingredients section, typically the first section on an OTC drug label, lists the therapeutic substances in the medication and their amount per unit (such as per tablet or teaspoon). Pay close attention to this section if you have allergies or need to take multiple medications, as the strength or amount of each active ingredient helps determine the product’s effectiveness and safety for your situation.

What Should I Look for in the Warnings Section?

The warnings section contains critical safety information, including the following:

  • Times to avoid using the product
  • Conditions that may require medical consultation before use
  • Possible side effects
  • Signs to stop using the product
  • Pregnancy and breastfeeding warnings
  • “Keep out of reach of children” warnings

How Do I Follow the Directions Properly?

The directions section tells you how much of the medication to take, how often to take it, and how to take it. Make sure to follow these instructions precisely to keep yourself safe and maximize your medication’s effectiveness.

Keep this important note in mind: Manufacturers often prescribe the dosage for children’s medications based on age or weight, so pay careful attention to those details to avoid under- or overdosing.

What Other Information Should I Check on the Label?

Make sure you pay attention to these information sections:

  • Purpose: The category of your medication (e.g., pain reliever, antihistamine, etc.).
  • Uses: The specific conditions or symptoms the product aims to treat.
  • Other Information: Storage instructions and other relevant details.
  • Inactive Ingredients: Potential allergens or substances that can interact with other medications.
  • Expiration Date: Peak effective dates.

How Can I Get Help Understanding Medication Labels?

If you have any questions about a section on an OTC drug label, consult a healthcare professional. A licensed and experienced pharmacist can provide you with guidance about the medication that can help with your condition, its potential interactions, and the proper way to take your selected OTC drug.
