What Should You Check Before Taking a New Medicine?

Starting a new medicine can be simple, but it is worth checking a few important details before the first dose.

Understanding what the medicine is, how to take it, and what to watch for can help reduce medication errors and prevent avoidable problems.

Starting a new medicine can be simple, but

Check the Medicine Name

Look at the label and confirm the name of the medicine.

For prescription medicines, also check that the prescription is intended for you. If the name, strength, or appearance is unexpected, contact the pharmacy before taking it.

Know Why You Are Taking It

Make sure you understand what the medicine is being used to treat.

Knowing the purpose of a medicine can make it easier to follow the instructions correctly and recognize when you may need to ask a question.

Check the Dose and Directions

Read the label carefully.

Important details may include:

  • How much to take
  • How often to take it
  • Whether to take it with food
  • Whether a specific time of day is recommended
  • How long to use it

Taking more or less than directed can cause problems or make the medicine less effective.

Review Your Other Medicines and Supplements

Tell your pharmacist or healthcare provider about all the products you use, including:

  • Prescription medicines
  • Over-the-counter medicines
  • Vitamins
  • Herbal products
  • Dietary supplements

Some medicines and supplements can interact with each other.

Check for Allergies or Previous Reactions

Make sure your pharmacist and prescriber know about any medication allergies or serious reactions you have had in the past.

It is also helpful to describe what happened during the reaction, since side effects and allergic reactions are not always the same thing.

Look for Important Warnings

Prescription labels and medication information may include instructions about:

  • Driving
  • Alcohol
  • Food
  • Sun exposure
  • Pregnancy or breastfeeding
  • Other medicines
  • Medical conditions

For over-the-counter medicines, the Drug Facts label includes warnings and directions that should be reviewed before use.

Know What to Do If You Miss a Dose

Missed-dose instructions can differ from one medicine to another.

Do not assume that taking two doses together is appropriate. Check the medication instructions or ask a pharmacist if you are unsure what to do.

Know When to Ask a Pharmacist

Ask a pharmacist or other qualified healthcare professional if:

  • The directions are unclear
  • The medicine looks different from what you expected
  • You are taking several medicines
  • You are unsure about food or drink interactions
  • You have had previous medication reactions
  • You develop a new or concerning side effect

Pharmacists can help explain medication instructions and identify potential medication-related problems.

Bottom Line

Before taking a new medicine, check the name, dose, directions, purpose, warnings, and possible interactions.

A few minutes spent reviewing the label and asking questions can help prevent medication errors.
