Polypharmacy means taking several medicines at the same time. It is often necessary, because many people have more than one condition. It does raise the chance of side effects and interactions, so keep an up-to-date list and have it reviewed by your doctor or pharmacist.

There is no need to be alarmed by the word. It describes a situation, not a mistake. Do not stop any medicine because you are worried about it. Talk to your doctor first.

Why people take several medicines

MedlinePlus says you may take more than one medicine for a single condition, or different medicines for more than one health problem. Older adults often have more than one health condition, so they are more likely to take several.

The risks

MedlinePlus lists these risks of taking multiple medicines:

  • You may be more likely to have side effects.
  • Certain medicines can increase the risk of falls.
  • You are at higher risk of interactions, where one medicine affects how another works. For example, one may make another stronger.

Medicines can also interact with food, drinks and supplements. It can be hard to keep track of when and how to take each one too. See how to manage multiple medications.

How to take several medicines more safely

  • Keep a list of everything, including over-the-counter medicines, vitamins, supplements and herbal products. MedlinePlus suggests keeping a copy in your wallet and at home. Here is what a good list includes.
  • Review it at each appointment with your doctor, and with your pharmacist.
  • Use one pharmacy if you can. The National Institute on Aging says this helps your pharmacist check whether a new medicine might cause a problem. If you can't, share your list with the pharmacist at each.
  • Ask before adding anything, including supplements. See supplements and how to track them.
  • Report new symptoms. Tell your doctor or pharmacist about anything new, such as dizziness, and ask if a medicine could be the cause.
  • Do not stop on your own. MedlinePlus says not to stop taking any medicine unless your provider tells you to.

Questions to ask at a medication review

  • What is each of these for?
  • Do I still need all of them?
  • Could any of them be causing this symptom?
  • Do any of them interact with each other, or with my supplements?
  • Can my schedule be made simpler?
