Managing New Medications After an ER Visit

Most people leave the ER with at least one change to their medications: a new prescription, a different dose, or an old pill they're told to stop. For an older adult already taking several medications, that one change can be easy to miss and hard to keep straight.

Medication mix-ups are one of the most common reasons older adults end up back in the hospital after an ER visit. The good news is that most of them are preventable with a little organization in the first few days.

This guide shows you how to sort out what changed, build a simple routine, spot problems early, and keep one accurate medication list that travels with your loved one. A free printable medication list is included at the end.

In the first 48 hours: sort out what changed

Before the first new dose, sit down with the discharge papers and every medication in the house. Health professionals call this "medication reconciliation." It means making sure the list on paper matches what's actually being taken.

1. Gather everything in one spot. Prescriptions, over-the-counter pills, vitamins, supplements, inhalers, eye drops, creams, and patches. Check the nightstand, bathroom, purse, and car.
2. Read the discharge medication list line by line. Look for words like new, start, change, increase, decrease, stop, hold, or resume.
3. Sort every medication into four groups:
   • New: started at the ER
   • Changed: same medication, different dose or timing
   • Stopped or on hold: do not take until a doctor says otherwise
   • Unchanged: keep taking as before
4. Set stopped medications aside. Put them in a bag labeled "STOPPED – do not take" so no one grabs them by habit. Don't throw them out until the PCP confirms.
5. Watch for duplicates. The same drug can have a brand name and a generic name (for example, Coumadin and warfarin). Two bottles of the same medicine is a common and dangerous mistake.
6. Call the pharmacist with any question. Pharmacists can review the full list for duplicates and interactions at no charge. It's one of the most underused free services in health care.

If anything on the discharge papers is unclear or seems to conflict with what the regular doctor prescribed, call the PCP or nurse line before giving the medication.

Build a routine that's hard to get wrong

A good system means no one has to remember. These habits make the biggest difference:

• Use one pharmacy. When every prescription goes through the same pharmacy, their system can flag interactions automatically. Fill the ER prescriptions there too.
• Use a weekly pill organizer. Choose one with morning, noon, evening, and bedtime slots if needed. Fill it once a week at the same time, using the medication list, not memory.
• Tie doses to daily habits. Morning pills with breakfast, evening pills after dinner. Set phone alarms for anything at an unusual time.
• Know which ones are time-sensitive. Antibiotics, blood thinners, insulin, seizure, and Parkinson's medications often need to be taken on time, every time. Ask the pharmacist which of yours are.
• Finish the course. Antibiotics and steroid tapers should be finished exactly as written, even if your loved one feels better.
• Line up refills. Ask the pharmacy about synchronizing refills so everything is picked up on the same day each month, and ask whether 90-day supplies or delivery are available.
• Decide who's in charge. If several family members help, pick one person to fill the organizer each week. Fewer hands means fewer mix-ups.

What side effects should you watch for in the first two weeks?

Older adults feel medication side effects more strongly, and they often look like "just getting older." Any change that starts after a new medication is worth noting, with the date and time.

Common signs to watch for:

• New dizziness, unsteadiness, or falls
• Confusion, sleepiness, or agitation that's new or worse
• Upset stomach, constipation, or diarrhea
• Unusual bruising or bleeding (especially with blood thinners)
• Swelling in the ankles, or sudden weight gain
• Rash or itching
• Low or high blood pressure or blood sugar readings, if you check them at home

Who to call:

• 911: swelling of the face, lips, or tongue; trouble breathing; chest pain; fainting; or someone who is very hard to wake
• Poison Control (1-800-222-1222): a double dose, the wrong pill, or someone else's medication taken by mistake, if the person is awake and stable
• Pharmacist or nurse line: a missed dose, mild side effects, or questions about mixing medications
• PCP: side effects that are bothersome but not urgent, or a medication that seems to be causing more problems than it solves

Never stop a new medication on your own without checking first. Some, like blood pressure pills and steroids, can cause problems if stopped suddenly.

Keep one list, and keep it current

A medication list is only useful if it's right. An outdated list can be worse than none, because doctors and paramedics will trust it.

Update the list every time:

• A medication is started, stopped, or the dose changes
• Your loved one comes home from the ER, hospital, rehab, or a specialist visit
• A new over-the-counter medicine, vitamin, or supplement is added
• The pharmacy switches to a different generic (the pill may look different)

Review it with a professional:

• Bring the list, or all the bottles in a bag, to every doctor visit, especially the ER follow-up
• Ask the PCP or pharmacist for a full review at least once a year, or sooner if your loved one takes five or more medications
• Ask at each review: "Is there anything on this list we can stop or reduce?"

Keep copies where they're needed:

• On the fridge, where paramedics are trained to look
• In your loved one's wallet or purse
• On the phone of each family member who helps with care
• With the home health, hospice, or assisted living team, if they're involved

Put the date on every version, and throw out the old copies so only the current one is in circulation.
