Staying healthy during cold and flu season is extra important when you have chronic kidney disease (CKD). Your body has to work harder to fight infections, and some common cold medicines can be risky for your kidneys. Here’s a simple plan to protect yourself, feel better faster, and know when to call your care team.
Why CKD Patients Must Be Extra Cautious
For someone with CKD, even a mild cold can turn serious quickly. Your immune system may not respond as strongly, and dehydration or certain medications can worsen kidney function. What feels like “just the flu” for someone else can trigger a chain reaction—fever, fluid loss, and medication side effects—that put unnecessary strain on your kidneys. That’s why prevention isn’t optional; it’s essential.
1. Get Vaccinated Early
Vaccines are your first line of defense against serious illness.
Why Vaccination Matters
People with CKD are more likely to experience severe flu symptoms or complications such as pneumonia or hospitalization. A yearly flu shot (injection) is strongly recommended. If you haven’t already, talk with your nephrologist about getting your pneumonia vaccine and staying up-to-date on COVID-19 boosters, since these illnesses can also impact kidney health.
Timing and Type of Vaccine
The best time to get vaccinated is early in the flu season—ideally before the end of October. Stick with injectable vaccines rather than nasal sprays, as the nasal form (LAIV) is not recommended for individuals with CKD or weakened immune systems.
2. Practice Good Hygiene Habits
Everyday Precautions
- Wash hands often with soap and water for at least 20 seconds.
- Avoid touching your eyes, nose, and mouth.
- Use hand sanitizer when soap isn’t available.
- Disinfect surfaces like phones, doorknobs, and keyboards.
Small Habits, Big Protection
CKD patients can help prevent infection by building small hygiene habits into their daily routine. Keeping sanitizer nearby, washing hands after appointments, and regularly cleaning shared items can make a major difference during high-risk months.
3. Avoid Close Contact with Sick People
Protecting Yourself and Loved Ones
IIt can be hard to avoid gatherings during the colder months, but keeping a safe distance from anyone showing symptoms—coughing, sneezing, or fever—is key. If someone in your household becomes sick, isolate when possible, disinfect shared areas, and use disposable towels or separate utensils.
Air Quality and Ventilation
Improving ventilation helps, too. Open a window for a few minutes each day or use an air purifier with a HEPA filter to help reduce airborne viruses.
4. Stay Warm and Keep Your Body Comfortable
Why Warmth Matters for CKD
Cold weather can increase blood pressure and make your heart and kidneys work harder. It can also trigger fatigue and dehydration. Maintaining a warm environment supports better blood flow and overall kidney function.
Simple Ways to Stay Warm
- Dress in layers and wear socks indoors.
- Use blankets and keep your home temperature comfortable.
- Stay hydrated with warm, kidney-friendly beverages such as herbal tea (without added sodium or caffeine).
- Prepare for power outages by keeping extra blankets and shelf-stable, kidney-safe foods on hand.
5. Be Cautious with Over-the-Counter (OTC) Medications
The Hidden Risk in Common Cold Medicine
Many popular OTC pain relievers and cold remedies contain NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen or naproxen, which can reduce blood flow to the kidneys. For CKD patients, these can be harmful—especially if you’re dehydrated or already taking prescription medications that affect kidney function.
Safer Alternatives
- Look for medications with acetaminophen (Tylenol) instead of NSAIDs, but always confirm with your doctor first.
- Avoid “multi-symptom” cold products, which often mix several active ingredients.
- Check labels carefully, even on herbal supplements.

6. Seek Medical Advice Early
Know When to Call Your Nephrologist
If you have CKD and start feeling sick, don’t wait until symptoms get worse. Contact your nephrology team right away if you experience:
- Fever over 101°F lasting more than 24–48 hours
- Shortness of breath, chest pain, or coughing up mucus
- Dizziness, dehydration, or reduced urine output
- Nausea or vomiting that prevents you from eating or drinking
Early treatment can prevent complications and help protect your kidneys from unnecessary stress.
7. Rest Over Reps: Avoid Exercise While Sick
When It’s Time to Rest
If you have a fever, congestion, or feel weak, skip workouts and focus on rest. Pushing through illness can prolong recovery and increase strain on your body. Once you’re feeling better and fever-free for at least 24 hours, gentle activity like stretching or short walks is safe to resume.
