Introduction
Prescription medicines play an important role in treating illnesses, managing chronic conditions, controlling symptoms, and improving quality of life. However, taking medication safely requires more than simply remembering to swallow a pill.
Understanding how to take prescription medication, following your healthcare provider's instructions, recognizing potential side effects, and knowing about possible drug interactions can help reduce preventable medication-related problems.
For patients in the United States, prescription medicines are available for many different conditions, including high blood pressure, diabetes, infections, pain, anxiety, depression, erectile dysfunction, and many others.
Every medication is different. The correct dose, timing, duration, and precautions depend on the specific medicine and the individual patient.
This guide explains important prescription medication safety tips that U.S. consumers should understand before and during treatment.
What Is Prescription Medication?
Prescription medication is medicine that requires authorization from a licensed healthcare professional before it can be dispensed by a pharmacy.
Unlike over-the-counter medicines, prescription drugs generally require professional evaluation because they may:
- Require individualized dosing
- Have significant side effects
- Interact with other medicines
- Require monitoring
- Be inappropriate for certain medical conditions
- Carry risks of misuse or dependence
Prescription medicines should always be used according to the instructions provided by your healthcare professional and pharmacist.
Why Medication Safety Matters
Taking medication incorrectly can reduce its effectiveness or increase the risk of adverse effects.
Common medication mistakes include:
- Taking the wrong dose
- Taking doses too close together
- Forgetting doses
- Taking someone else's medication
- Combining medicines without checking for interactions
- Stopping certain medicines suddenly
- Taking expired or improperly stored medication
- Mixing certain medicines with alcohol
- Using prescription medication without appropriate medical supervision
Learning basic medication safety can help patients become more informed participants in their healthcare.
How to Read Prescription Instructions
Your prescription label contains important information about how to use your medicine.
Depending on the medication, the label may include:
- Medication name
- Strength
- Directions
- Quantity
- Number of refills
- Prescribing healthcare professional
- Pharmacy information
- Patient name
- Special warnings
For example, instructions may tell you to take a medicine once daily, twice daily, with food, or at a particular time.
If you don't understand an instruction, ask your pharmacist before taking the medication rather than guessing.
Take Your Medicine at the Correct Time
Some medicines work best when taken at consistent times.
Taking medication according to the prescribed schedule can help maintain the intended amount of medicine in your body.
Helpful strategies include:
- Taking your medicine at the same time each day
- Setting a phone reminder
- Using a medication organizer when appropriate
- Keeping a written medication schedule
- Linking medication time to an established daily routine
Do not change the schedule simply because you feel better unless your healthcare professional tells you to do so.
Never Change Your Dose on Your Own
Taking more medication than prescribed does not necessarily make it work better.
An excessive dose may increase the risk of side effects or overdose.
Similarly, taking less than prescribed may make treatment less effective.
Do not:
- Increase your dose
- Reduce your dose
- Take extra doses
- Take medication more frequently
- Extend treatment
- Stop treatment
without discussing the change with your healthcare professional.
What Should You Do If You Miss a Dose?
The appropriate response to a missed dose depends on the medication.
For many medicines, the general instruction is to take the missed dose when remembered unless it is almost time for the next scheduled dose. However, this is not appropriate for every medication.
Some medicines have specific missed-dose instructions.
Check the medication guide or prescription label, and contact your pharmacist or healthcare professional if you're unsure.
Do not automatically double your next dose unless a healthcare professional specifically tells you to do so.
Understanding Medication Side Effects
All medicines can potentially cause side effects.
Some side effects may be mild and temporary, while others can be serious.
Common medication side effects can include:
- Nausea
- Headache
- Dizziness
- Drowsiness
- Stomach discomfort
- Constipation
- Diarrhea
- Fatigue
The possible side effects depend on the specific medication.
Read the medication information supplied with your prescription so you understand which symptoms require medical attention.
When Should You Seek Medical Help?
Some symptoms require prompt medical attention.
Seek emergency medical assistance if you experience potentially serious symptoms such as:
- Severe difficulty breathing
- Loss of consciousness
- Severe allergic reaction
- Severe chest pain
- Seizures
- Severe confusion
- Signs of a serious overdose
For less urgent but concerning symptoms, contact your healthcare professional or pharmacist.
If you are unsure whether a symptom is serious, it is safer to ask a healthcare professional rather than ignoring it.
Understanding Drug Interactions
A drug interaction occurs when one medicine, food, supplement, or substance affects how another medication works.
Some interactions can increase side effects, while others can reduce the effectiveness of treatment.
Before starting a new medicine, tell your healthcare professional about everything you take, including:
- Prescription medications
- OTC medicines
- Vitamins
- Herbal supplements
- Dietary supplements
- Recreational substances
This information can help your healthcare team identify potential interactions.
Prescription Medicines and Alcohol
Alcohol can interact with certain prescription medicines.
Depending on the medication, combining alcohol with prescription drugs may increase:
- Drowsiness
- Dizziness
- Impaired coordination
- Low blood pressure
- Stomach irritation
- Liver-related risks
- Breathing problems
Certain medications, particularly medicines that depress the central nervous system, can pose especially serious risks when combined with alcohol.
Do not assume that a small amount of alcohol is safe with every prescription medicine.
Ask your healthcare professional or pharmacist whether alcohol should be avoided with your specific medication.
Prescription Medicines and Driving
Some medications can cause:
- Drowsiness
- Dizziness
- Blurred vision
- Reduced reaction time
- Confusion
- Impaired coordination
These effects can make driving or operating machinery dangerous.
When starting a new prescription, check whether the medication carries warnings about driving or activities requiring alertness.
Until you know how a medication affects you, use caution with driving and other potentially hazardous activities.
Keep an Updated Medication List
Maintaining an accurate medication list is one of the simplest ways to improve medication safety.
Your list should include:
- Medication name
- Strength
- Dose
- How often you take it
- Reason for taking it
- Allergies
- Supplements and OTC medicines
Keep the list updated whenever a medication is started, stopped, or changed.
Bring it to medical appointments and share it with your healthcare providers.
Tell Your Healthcare Provider About Allergies
Always tell your healthcare professional about known medication allergies.
A medication allergy can cause symptoms such as:
- Rash
- Hives
- Swelling
- Breathing difficulties
- Severe allergic reactions
Do not assume that every medication with a similar name is safe if you have previously experienced an allergic reaction.
Your pharmacist can also help check medication ingredients.
Store Prescription Medicines Properly
Proper storage can help maintain medication quality and prevent accidental exposure.
Unless your medication instructions say otherwise:
- Store medicines in a dry location.
- Follow the temperature instructions on the label.
- Keep medications away from excessive heat and moisture.
- Keep medicines out of reach of children and pets.
- Keep medicines in their original containers when practical.
Some medications require refrigeration or other special storage conditions, so always follow the specific storage instructions for your medicine.
Never Share Prescription Medication
Prescription medicines are prescribed based on an individual's health history and treatment needs.
Even if another person has symptoms that appear similar to yours, your medication may not be appropriate for them.
Never share prescription medication with:
- Friends
- Family members
- Coworkers
- Anyone else
Likewise, don't take medication prescribed to another person.
Don't Stop Certain Medicines Suddenly
Some prescription medicines should not be stopped abruptly after regular use.
Suddenly discontinuing certain medications can result in withdrawal symptoms, rebound symptoms, or other complications.
This can be particularly important with certain:
- Benzodiazepines
- Antidepressants
- Steroids
- Blood-pressure medicines
- Seizure medications
- Other long-term therapies
If you want to stop a medication, talk to your healthcare professional first. They may recommend gradually reducing the dose.
Be Careful With Multiple Medications
Taking several medications at the same time is sometimes necessary, particularly for people managing multiple health conditions.
However, the more medications you take, the more important it becomes to review potential interactions.
Ask your pharmacist or healthcare provider to review your complete medication list if you regularly take multiple prescription or OTC medicines.
This process can help identify duplicate ingredients, potentially harmful combinations, or unnecessary medications.
Prescription Medicines and Online Pharmacies
Many U.S. consumers search online for prescription medicines because of convenience and the ability to compare pharmacies.
However, not every website selling medicine online is legitimate.
The FDA recommends that consumers use caution when purchasing medicines online and verify that an online pharmacy is safe and operating appropriately.
Before using an online pharmacy, look for important indicators such as:
- A prescription requirement when appropriate
- A licensed pharmacist
- Clear contact information
- Appropriate pharmacy licensing
- Secure website practices
- Transparent medication information
Be especially cautious if a website:
- Offers prescription medicine without requiring an appropriate prescription
- Makes unrealistic health claims
- Offers prices that appear unusually low
- Does not provide clear contact information
- Uses unclear or misleading product information
How to Avoid Counterfeit Medicines
Counterfeit medicines can contain incorrect ingredients, incorrect amounts of active ingredients, or potentially harmful substances.
Consumers should be particularly careful when purchasing medicines from unfamiliar websites or unauthorized sellers.
Don't rely solely on:
- Product photographs
- Customer reviews
- Social media advertisements
- Extremely low prices
- Claims such as "100% safe"
Verify the pharmacy and the medication source before making a purchase.
Check Your Medicine Before Taking It
Before taking a new medication, check:
1. Name
Make sure the medication matches your prescription.
2. Strength
Check the strength printed on the label.
3. Directions
Follow the prescribed instructions.
4. Expiration date
Don't use medication that has expired unless specifically instructed by a healthcare professional.
5. Appearance
If the medication looks unexpectedly different, ask your pharmacist before taking it.
Medication Safety for Older Adults
Older adults may take multiple medications for different conditions.
Age-related changes in kidney and liver function can also affect how some medications are processed.
For older adults, medication safety may include:
- Regular medication reviews
- Checking for drug interactions
- Reviewing doses
- Keeping an updated medication list
- Monitoring for dizziness or falls
- Following up regularly with healthcare providers
Caregivers should also communicate medication changes with the patient's healthcare team when appropriate.
Medication Safety for Children
Children should only receive medication specifically recommended or prescribed for them.
Never assume that an adult medication is safe for a child at a smaller dose.
Children's medications may have different dosing requirements based on age, weight, and medical condition.
Always follow the instructions provided by the child's healthcare professional.
Safe Disposal of Unused Medicines
Unused or expired medicines should be disposed of appropriately.
The FDA provides guidance on medication disposal, including information about drug take-back options and other disposal methods.
If you're unsure how to dispose of a particular medication, ask your pharmacist or check the FDA's current disposal guidance.
Do not automatically flush medication down the toilet unless the specific medicine is identified for flushing under applicable disposal guidance.
Common Prescription Medication Mistakes to Avoid
Some common mistakes include:
Taking Someone Else's Medication
Never use another person's prescription.
Taking Extra Doses
More medication does not necessarily mean better results.
Stopping Suddenly
Some medications require gradual dose reduction.
Ignoring Side Effects
Persistent or serious symptoms should be discussed with a healthcare professional.
Mixing Medicines Without Checking
Even OTC products and supplements can interact with prescription medicines.
Forgetting Medication Instructions
Read the prescription label and medication guide carefully.
Buying From Unverified Websites
A professional-looking website does not necessarily mean the pharmacy is legitimate.
Questions to Ask Your Pharmacist
When receiving a new prescription, consider asking:
- What is this medicine used for?
- How should I take it?
- Should I take it with food?
- What should I do if I miss a dose?
- What side effects should I watch for?
- Does it interact with my other medications?
- Should I avoid alcohol?
- Can I drive after taking it?
- How should I store it?
- How should I dispose of unused medication?
These questions can help you better understand your treatment.
Conclusion
Prescription medication safety starts with understanding your medicine and following the instructions provided by your healthcare professional.
Take medications exactly as prescribed, keep an updated medication list, check for potential drug interactions, follow storage instructions, and avoid sharing prescription medicines with others.
If you purchase prescription medication online, take additional care to verify that you're dealing with a legitimate pharmacy and that the medicine is obtained through appropriate channels.
Most importantly, don't make major changes to your medication regimen on your own. If you have questions about your dose, side effects, interactions, or treatment duration, speak with your healthcare professional or pharmacist.
