Cold and Flu Treatment in Southlake, TX

Most colds and most flu do not need a prescription, and saying so plainly is more useful than sending you home with an antibiotic that will do nothing. What we do offer is a same-day appointment, an honest read on what you have, antivirals when they will actually help, and clear instructions on what should happen next.

Telling them apart

A cold builds gradually: sore throat, then congestion, then cough, usually without much fever. Flu arrives suddenly, with fever, body aches and exhaustion that puts people in bed. COVID overlaps with both and can look like either.

Clinically the distinction matters mostly because it changes whether antivirals are worth using and how closely we want to watch you.

Testing, when it helps

We test when the result changes something. That means when you are in a higher-risk group, when you are within the window for antivirals, when you live with someone vulnerable, or when the answer affects your return to work.

We can test for flu, COVID and strep in the office and have the result before you leave.

If none of those apply and you are otherwise healthy on day four of a cold, a test tells us something interesting and changes nothing.

Antivirals

Oseltamivir shortens flu by roughly a day in healthy adults when started within 48 hours. That modest benefit becomes substantially more important if you are over 65, pregnant, immunosuppressed, or living with asthma, COPD, heart failure or diabetes, where the goal is preventing complications rather than shortening symptoms.

For COVID, nirmatrelvir-ritonavir is worth considering in higher-risk patients and needs starting within five days. It interacts with a long list of common medications, including several statins and blood thinners, so we check your list carefully rather than prescribing it reflexively.

Antibiotics, honestly

Colds and flu are viral. Antibiotics do nothing for them except cause diarrhea, yeast infections and an individual contribution to resistance that comes back around eventually.

Green or yellow mucus does not mean bacterial infection. It means your immune system is working, and it is one of the most persistent myths in medicine.

If we do not prescribe an antibiotic, you should still leave knowing exactly what to do: what to take, what to expect, how long it should last, and the specific signs that mean come back. That is the standard we hold ourselves to.

What actually helps

Fluids and rest, genuinely. Acetaminophen or ibuprofen for fever and aches. Saline nasal rinses, which do more for congestion than most oral decongestants. Honey for cough, which outperforms most over-the-counter cough syrups in trials. A humidifier at night.

Oral decongestants raise blood pressure and can cause insomnia and palpitations. If you have hypertension, tell us so we can suggest something else. Phenylephrine, the oral decongestant in most products since pseudoephedrine moved behind the counter, has been found ineffective by the FDA.

When it is not just a cold

If you have asthma or COPD, a viral infection is the most common trigger for a serious flare. Use your action plan and call us early rather than waiting to see.

Symptoms that improve and then worsen around day seven to ten suggest a bacterial complication such as sinusitis or pneumonia, and that is worth being seen for.
