Key points
- Medicines affect people differently, and finding the right one can take more than one try, so side effect reports are useful information.
- Short notes on what you noticed, when it started and how strong it was make the conversation easier.
- Do not stop or change a medicine on your own: talk with your prescriber first.
- FDA Medication Guides, pharmacy labels, MedlinePlus and your pharmacist are reliable places to read about a medicine.
- Call your prescriber right away about problems, and call 911 for an emergency.
Why side effects are worth raising
The Food and Drug Administration (FDA) says both prescription and over-the-counter drugs have side effects, also called adverse reactions. They can range from minor problems to life-threatening events. Things like age, other medicines, supplements and other health conditions can affect who has them.
The National Institute of Mental Health (NIMH) notes that medications affect people in different ways, and that it may take several tries to find the one that works best with the fewest side effects. That makes your report part of the treatment, not a complaint about it. Your prescriber cannot adjust a plan for something they do not know about.
The FDA also notes that side effects can show up when you start a new drug or supplement, stop a drug you have taken for a while, or increase or decrease a dose. Those moments are worth paying extra attention to.
Keep simple notes
Memory gets fuzzy between visits, especially when you are not feeling well. A few lines in your phone or a notebook can help. You do not need medical words: describe what you noticed in your own language.
- What you noticed, in plain words.
- When it started, and whether it followed a new medicine or a change in dose.
- How often it happens and how strong it feels.
- Whether it affects sleep, work, school, relationships or daily tasks.
- Anything new you started, including over-the-counter medicines, vitamins or supplements.
What to say at your visit
Start with what matters most to you. If one effect is making it hard to keep taking the medicine, say so plainly. Prescribers need honest information, and it helps to know what you would most like to change.
The FDA suggests working with your health care professional to see whether adjusting the dose or switching to a different medicine could ease a side effect, and notes that other options, such as a lifestyle change, may be suggested. Those are decisions for you and your prescriber to make together.
Useful questions include: Is this a known effect of this medicine? Is it likely to ease with time? What should I do if it gets worse? Which signs mean I should call you before our next visit?
Do not stop or change a medicine on your own
When a side effect is unpleasant, stopping can feel like the obvious fix. NIMH advises that people should not stop taking a prescribed medication without the help of a health care provider, who can adjust the plan safely. It says stopping a medication too soon may cause unpleasant or harmful side effects.
The same goes for changing how much you take or when you take it. Call your prescriber instead. NIMH says to call a health care provider right away if you have problems with your medication or are worried it might be doing more harm than good.
Where to read reliable information
The FDA says you can ask your health care professional for information about a drug when you receive a prescription. FDA-approved labeling for patients includes Medication Guides and Patient Information, which list possible common and serious side effects. The pharmacy label and any stickers on the bottle or box may also explain how to take the drug and possible side effects.
MedlinePlus, from the National Library of Medicine, has a drug information section that covers side effects and precautions for prescription and over-the-counter medicines. Pharmacists are another good resource: MedlinePlus notes they provide information about medicines and consult with providers about interactions and side effects.
Reading about a medicine can raise new questions. Bring them to your prescriber rather than deciding alone.
When it is urgent
Some reactions cannot wait for an appointment. If a reaction feels serious or life-threatening, call 911 or go to the nearest emergency room. For anything that worries you but is not an emergency, call your prescriber right away rather than waiting for your next visit.
The FDA runs MedWatch, a program for reporting serious problems with medicines. You or your health care provider can report a serious side effect there. Reporting does not replace calling your prescriber.

Common questions
Should I stop my medicine if I get side effects?
Not on your own. NIMH advises against stopping a prescribed medication without the help of a health care provider, because stopping too soon may cause unpleasant or harmful side effects. Call your prescriber to talk it through. If a reaction feels serious or life-threatening, call 911 or go to the nearest emergency room.
Where can I read about my medicine's side effects?
Start with what came with your prescription. The FDA says patient labeling such as Medication Guides and Patient Information lists possible common and serious side effects, and the pharmacy label may help too. MedlinePlus has a drug information section, and your pharmacist can answer questions. Bring anything confusing to your prescriber.
Is a small side effect worth mentioning?
Yes. A side effect that seems minor can still affect your sleep, work or willingness to keep taking a medicine. NIMH notes that finding the medicine with the fewest side effects can take more than one try, so what you report helps your prescriber. Short notes on when it started and how often it happens are enough.
