FEVER TREATMENT
A fever usually means your body is fighting an infection, and most clear up on their own within a few days. When a fever runs high, lingers, or comes with symptoms that worry you, it helps to know what is behind it. Lifetime Primary Care can check your temperature and symptoms, look for the source, and help you decide whether you need testing, treatment, or rest.
Key Takeaways
In adults, a fever is generally an oral temperature of 100.4°F (38°C) or higher
Most fevers come from a viral or bacterial infection and pass within three to four days
Fluids, rest, and a fever reducer such as acetaminophen or ibuprofen ease discomfort while the cause clears
A temperature of 103°F (39.4°C) or higher, or a fever lasting more than three days, is worth a call to your provider
Treating what is causing the fever matters more than chasing the number on the thermometer
A fever is a temporary rise in body temperature, usually a sign that your immune system has switched on to fight something off. Normal body temperature sits around 98.6°F (37°C), though it shifts through the day and varies from person to person. A low-grade fever (100.4°F to 102°F) often does not need treatment and can actually help your body clear an infection. What matters is how you feel and what else is happening alongside the fever.
Common Causes of a Fever
A fever points to something else going on in your body, so the goal is to find the source. Frequent causes in adults include:
Viral infections such as a cold or the flu, COVID-19, or other respiratory illnesses
Bacterial infections, including strep throat, a urinary tract infection, or a sinus or ear infection
Heat exhaustion or dehydration
Certain medications or recent vaccinations
Inflammatory conditions, which can cause a fever that lingers without an obvious infection
Because so many things can raise your temperature, a fever that does not fit a clear pattern is worth having looked at.
How We Treat a Fever
Your provider starts by checking your temperature and other vital signs, then asks about your symptoms, recent exposures, and how long the fever has lasted. From there, the focus shifts to the cause. We see fever patients in person in Hoover, AL, or by telehealth, with same-week appointments often available.
Care may include:
Symptom relief with fluids, rest, light clothing, and a fever reducer (acetaminophen or ibuprofen) when the fever is uncomfortable
Testing such as a rapid strep, flu, COVID, or urine test to pin down an infection
Treating the source, which may mean antibiotics for a confirmed bacterial infection or supportive care for a virus
A follow-up plan so you know what to watch for and when to check back in
A fever from a virus often improves with rest and fluids alone, while a bacterial cause may need a prescription. Finding out which one you are dealing with is the point of the visit.
When to See a Provider
Most mild fevers can be managed at home. Reach out if:
Your temperature reaches 103°F (39.4°C) or higher
A fever lasts more than three days or keeps climbing
The fever does not come down with over-the-counter medication
You also have pain with urination, back pain, or a sore throat that is getting worse
You have a chronic condition (such as diabetes or heart disease) that makes infections riskier
Seek emergency care for a fever with trouble breathing, chest pain, confusion, a stiff neck, a severe headache, repeated vomiting, or signs of dehydration. If your fever is harder to shake than it should be, Lifetime Primary Care can help you find the cause and feel better. Book an appointment online or by telehealth when appropriate.
Frequently Asked Questions
-
Not always. A low-grade fever can help your body fight infection, so if you feel okay, rest and fluids may be enough. If the fever is making you miserable or climbs above 102°F, a fever reducer can help. Follow the label, and check with your provider first if you take other medications or have liver or kidney concerns
-
You often cannot tell from the temperature alone, since a cold, the flu, COVID-19, and a urinary tract infection can all cause similar fevers. Until you know the cause, it is smart to wash your hands often, cover your cough, and stay home if you can. Testing during your visit can sort out what is going on.

Description text goes hereYes. A fever can rise and fall over the course of an illness, often lower in the morning and higher in the evening. A fever that breaks and then returns, or one that keeps cycling for more than a few days, is a good reason to be seen.
