Know when to seek urgent care
Some symptoms need immediate medical attention. Call emergency services right away if you have any signs of a severe allergic reaction or a life threatening symptom.
Trouble breathing, wheezing, or swelling of the lips, tongue, mouth, or throat
Fainting, chest pain, or a very fast or very slow heartbeat
A severe, spreading rash or hives with dizziness or vomiting
Confusion, sudden weakness, slurred speech, or new severe headache
High fever, stiff neck, or signs of severe infection
Black or bloody stools, vomit that looks like coffee grounds, or uncontrolled bleeding
If you are uncertain whether a symptom is an emergency, prioritize safety and contact your clinician or emergency services immediately.
Build a plan with your care team
A clear plan makes side effects easier to prevent and manage.
Before starting a new medicine or treatment
Share your complete medication list, including vitamins and herbal products
Tell your clinician about previous reactions and allergies
Ask what side effects are common, which ones are serious, and what to do if they occur
Ask whether to take the medicine with food or water, and the best time of day
Confirm any lab tests or monitoring you may need
During the first weeks
Use a simple symptom diary to track what you feel and when it happens
Take medicines exactly as prescribed and set reminders if needed
Contact your pharmacist or clinician if a side effect is new, persistent, or disrupting daily life
Reporting serious problems
If you experience a serious reaction, your clinician may advise reporting it to national safety programs. Reporting helps keep medicines safer for everyone.

Everyday strategies to ease common side effects
Talk with your clinician or pharmacist before starting any over the counter product. These tips are general and may not fit every condition or medicine.
Nausea or upset stomach
Take small, frequent meals and choose bland foods when needed
Sip clear fluids often to stay hydrated
Limit strong smells and greasy or spicy foods
Ask your clinician about prescription or over the counter options if nausea continues
Constipation
Increase fiber gradually with fruits, vegetables, beans, and whole grains
Drink enough water through the day unless you have fluid limits
Keep moving with gentle physical activity as you are able
If lifestyle steps are not enough, ask about stool softeners or other options that are safe for you
Diarrhea
Drink fluids with electrolytes to prevent dehydration
Choose simple foods such as bananas, rice, applesauce, and toast as tolerated
Avoid alcohol and caffeine until symptoms improve
Ask about nonprescription medicines if appropriate and know when to seek care if diarrhea lasts or is severe
Dizziness or feeling faint when standing
Stand up slowly from sitting or lying positions and pause before walking
Drink enough water unless you are on fluid restrictions
Review your medicines with your clinician if dizziness is frequent
Check blood pressure as advised and report low readings or symptoms
Skin reactions such as rash or hives
Stop new products on the skin and avoid scratching
Use gentle cleansers and unscented moisturizers
Protect skin from sun exposure
Seek urgent care if there is swelling of the face or throat, trouble breathing, dizziness, or a rapidly worsening rash
Prevent harmful interactions
Interactions can make side effects more likely or more severe.
Keep an up to date list of all medicines and supplements and share it at every visit
Use one pharmacy when possible so the pharmacist can check for interactions
Ask about foods and drinks that interact with your medicines, including alcohol and grapefruit
Read the medication guide that comes with each prescription and ask questions if anything is unclear
Good habits at home help prevent errors and unintentional harm.
Store medicines in a cool, dry place away from children and pets
Keep medicines in original containers unless you use a clearly labeled pill organizer
Check expiration dates and replace as directed
Dispose of unused or expired medicines using a take back program or mail back envelope when available
If a take back option is not available, follow federal guidance for at home disposal and only flush medicines on the special flush list when instructed
Your story is bigger than pain. We can help you find relief.
Track symptoms and stay on schedule
Organization and reminders make it easier to stay on track and spot patterns.
Use a weekly pill organizer or an automatic dispenser if your regimen is complex
Set phone alarms or use a reminder app and keep a written schedule in a visible spot
Ask a caregiver to double check your pill organizer if you need support
Bring your symptom diary to visits to help your clinician fine tune your plan
