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.

  1. Trouble breathing, wheezing, or swelling of the lips, tongue, mouth, or throat
  2. Fainting, chest pain, or a very fast or very slow heartbeat
  3. A severe, spreading rash or hives with dizziness or vomiting
  4. Confusion, sudden weakness, slurred speech, or new severe headache
  5. High fever, stiff neck, or signs of severe infection
  6. 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

  1. Share your complete medication list, including vitamins and herbal products
  2. Tell your clinician about previous reactions and allergies
  3. Ask what side effects are common, which ones are serious, and what to do if they occur
  4. Ask whether to take the medicine with food or water, and the best time of day
  5. Confirm any lab tests or monitoring you may need

During the first weeks

  1. Use a simple symptom diary to track what you feel and when it happens
  2. Take medicines exactly as prescribed and set reminders if needed
  3. 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.

Understood Care has a team of nurses, advocates, and healthcare professionals who will work with you and coordinate with your clinicians to put the plan into action.

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

  1. Take small, frequent meals and choose bland foods when needed
  2. Sip clear fluids often to stay hydrated
  3. Limit strong smells and greasy or spicy foods
  4. Ask your clinician about prescription or over the counter options if nausea continues

Constipation

  1. Increase fiber gradually with fruits, vegetables, beans, and whole grains
  2. Drink enough water through the day unless you have fluid limits
  3. Keep moving with gentle physical activity as you are able
  4. If lifestyle steps are not enough, ask about stool softeners or other options that are safe for you

Diarrhea

  1. Drink fluids with electrolytes to prevent dehydration
  2. Choose simple foods such as bananas, rice, applesauce, and toast as tolerated
  3. Avoid alcohol and caffeine until symptoms improve
  4. Ask about nonprescription medicines if appropriate and know when to seek care if diarrhea lasts or is severe

Dizziness or feeling faint when standing

  1. Stand up slowly from sitting or lying positions and pause before walking
  2. Drink enough water unless you are on fluid restrictions
  3. Review your medicines with your clinician if dizziness is frequent
  4. Check blood pressure as advised and report low readings or symptoms

Skin reactions such as rash or hives

  1. Stop new products on the skin and avoid scratching
  2. Use gentle cleansers and unscented moisturizers
  3. Protect skin from sun exposure
  4. 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.

  1. Keep an up to date list of all medicines and supplements and share it at every visit
  2. Use one pharmacy when possible so the pharmacist can check for interactions
  3. Ask about foods and drinks that interact with your medicines, including alcohol and grapefruit
  4. Read the medication guide that comes with each prescription and ask questions if anything is unclear

Safe use, storage, and disposal at home

Good habits at home help prevent errors and unintentional harm.

  1. Store medicines in a cool, dry place away from children and pets
  2. Keep medicines in original containers unless you use a clearly labeled pill organizer
  3. Check expiration dates and replace as directed
  4. Dispose of unused or expired medicines using a take back program or mail back envelope when available
  5. 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

Track symptoms and stay on schedule

Organization and reminders make it easier to stay on track and spot patterns.

  1. Use a weekly pill organizer or an automatic dispenser if your regimen is complex
  2. Set phone alarms or use a reminder app and keep a written schedule in a visible spot
  3. Ask a caregiver to double check your pill organizer if you need support
  4. Bring your symptom diary to visits to help your clinician fine tune your plan
