Sinus infections are common after 65 and can be more uncomfortable or prolonged due to immune changes, drier nasal passages, chronic conditions, and certain medications; most cases still improve with hydration, saline rinses, warm compresses, rest, and cautious use of OTC pain relievers, while antibiotics are usually unnecessary unless symptoms exceed 10 days, are severe, or worsen after initial improvement. There are several factors to consider, including how to tell a cold from sinusitis, which medications to avoid, prevention tips, and urgent red flags like eye swelling, vision changes, severe headache, high fever, or confusion; see the complete guidance below for details that may affect your next healthcare steps.
A sinus infection—also called sinusitis—is common at any age, but it can be more uncomfortable and sometimes more complicated for women over 65. Changes in the immune system, existing health conditions, and medications can all affect how sinus infections feel and how long they last. The good news is that most sinus infections are treatable, and many improve with the right care and timely guidance.
This guide explains what a sinus infection is, why it matters more as we age, how to recognize symptoms, and what relief options are supported by credible medical evidence. The goal is to help you feel informed, not alarmed, and to know when it's time to speak to a doctor.
A sinus infection happens when the lining of the sinuses—air-filled spaces in the bones of your face—becomes inflamed and swollen. This swelling blocks normal drainage, allowing mucus to build up. Germs (viruses, bacteria, or rarely fungi) can then grow more easily.
There are different types of sinus infections:
In older adults, sinus infections may last longer or feel more intense if the immune response is slower.
As we age, the body changes in ways that can affect sinus health:
These factors do not mean a sinus infection is dangerous by default—but they do mean it deserves careful attention.
Symptoms of a sinus infection can vary, and not everyone has all of them. Common signs include:
In women over 65, symptoms may be more subtle, such as ongoing fatigue or pressure without a fever.
If you're experiencing any combination of these symptoms and want to better understand what might be causing them, Ubie's free AI-powered Sinusitis symptom checker can help you get personalized insights in just a few minutes.
Many sinus infections start as colds, but there are differences:
Understanding this difference can help you decide when home care is enough and when medical advice is wise.
Most sinus infections—especially viral ones—improve with supportive care. Credible medical organizations support the following approaches:
These steps are often helpful and low-risk:
Some medications may help, but older adults should be cautious:
Avoid long-term use of decongestant nasal sprays unless a doctor advises it, as they can worsen congestion over time.
Always check with a pharmacist or doctor if you take medications for blood pressure, heart disease, or glaucoma.
Many people assume a sinus infection automatically needs antibiotics. In reality:
Using antibiotics when they aren't needed can cause side effects and antibiotic resistance, which is especially important to avoid in later life.
Serious complications from a sinus infection are rare, but they are more likely in older adults or those with weakened immune systems.
Contact a doctor promptly if you notice:
These symptoms need medical evaluation and should not be ignored.
Prevention can reduce how often sinus infections occur:
Small daily habits can make a noticeable difference over time.
You should speak to a doctor if:
A doctor can determine whether imaging, prescription medication, or referral to a specialist is needed.
A sinus infection can be frustrating, especially when it lingers. For women over 65, the key is balance—taking symptoms seriously without assuming the worst. Most sinus infections resolve with proper care, awareness, and timely guidance.
If you're uncertain about your symptoms, using a trusted tool like a symptom check for Sinusitis can be a helpful first step. From there, don't hesitate to speak to a doctor about anything that feels serious or life-threatening.
With the right information and support, sinus infection relief is very achievable at any age.
