The final part of our respiratory season series. We’ve covered telling the illnesses apart, this year’s vaccines, urgent care versus the ER, and the school-season sick cycle. We close with the group for whom all of this works differently.
The Sentence That Costs People the Most
“I’ll give it a couple of days and see if it gets better.”
For most healthy adults that’s sensible. For a meaningful slice of our patients it’s the decision that turns a rough week into a hospital stay, because the treatments that change the course of flu and COVID work best early — and “early” means sooner than most people think to come in.
Are We Talking About You?
This is a longer list than most people expect, and a lot of folks on it don’t think of themselves as high-risk:
- Adults 65 and older
- Anyone pregnant, and for about two weeks after delivery
- Asthma, COPD, or any chronic lung condition
- Heart disease, including well-controlled heart disease
- Diabetes, type 1 or type 2
- Kidney or liver disease
- A weakened immune system — from a condition, or from medication that suppresses it
- Significant obesity
- Neurological conditions affecting swallowing or clearing the airway
- Anyone living in a nursing home or long-term care
Two things people get wrong about this list. First: managed is not the same as exempt. Well-controlled asthma and well-controlled diabetes are still on it. Second: being a healthy, active 68-year-old doesn’t take you off it. Age alone qualifies, and the immune system changes with age regardless of how good the rest of your health is.
What “The Window” Actually Means
You’ve probably heard that flu antivirals have to be started within 48 hours. That’s most of the truth, and the missing part matters.
Within 48 hours of symptoms starting is when antivirals work best. That’s the target and it’s worth organizing your week around.
But here’s what doesn’t get said often enough: for people at increased risk of complications, treatment is still recommended even when it’s started after that 48-hour mark. Later is less effective. Less effective is not the same as pointless. If you’re in one of the groups above and you’re on day three wondering whether you’ve missed your chance — you haven’t necessarily, and it’s worth coming in to find out rather than assuming the door closed.
For COVID, the window is longer. Oral antiviral treatment is generally started within five days of symptoms beginning.
Don’t Let Us Oversell This
We’d rather you have accurate expectations than enthusiastic ones.
In an otherwise healthy adult, flu antivirals shorten the illness by roughly a day. That’s real, but it’s not a miracle, and on its own it wouldn’t be much of an argument for anything.
The argument is different for people at higher risk. In that group the point was never the day of symptom relief — it’s reducing the chance that flu turns into pneumonia, into a hospital admission, into a cardiac event in someone whose heart was already working hard. That’s a different order of benefit, and it’s why the same medication is worth much more to a 70-year-old with COPD than to a healthy 30-year-old.
There are a few options. Oseltamivir is the familiar one, taken over several days. Baloxavir is a single dose, and a generic version was approved recently, which should make it considerably more affordable this season than it has been. Which one makes sense depends on your health, your other medications, and how far into the illness you are. That’s a conversation, not a menu.
Bring Your Medication List. Seriously.
If there’s one practical thing to take from this page, it’s this.
The oral COVID antiviral contains ritonavir, which interferes with how the body processes a long list of other drugs — statins, blood thinners, several heart medications, and others. Those interactions can be serious. They’re also usually manageable, but only if the provider knows what you’re taking before writing anything.
So bring the actual list. A phone photo of your pill bottles works fine. Don’t rely on remembering, and don’t leave off the supplements — some of those interact too. And never stop or adjust a medication on your own because you read something about interactions. That’s the provider’s job to sort out, and it usually takes about two minutes.
Making the Visit Fast
Because when you’re feeling terrible, the barrier to coming in is everything.
Check in online before you leave and hold your place. Bring your medication list, your insurance card, and a rough sense of when symptoms actually started — that last one genuinely matters for treatment decisions, so think back to the first hour you felt off, not the day it got bad.
We’ll test for flu, COVID, RSV or strep as appropriate, examine you, and if antiviral treatment makes sense a provider will talk it through with you. We’re open seven days a week across Brooklyn and Queens, which matters when symptoms start on a Friday evening and waiting for Monday would cost you the window.
If leaving the house is genuinely not possible, a telehealth visit can be a starting point. For higher-risk patients, though, there’s real value in someone listening to your chest and checking your oxygen — a provider can tell you whether a remote visit is enough in your case.
Where Our Help Stops
We said this in Part 3 and it belongs here too, more pointedly, because this group is the one most likely to need it.
Go to an emergency room, or call 911, for:
- Difficulty breathing, or breathlessness while sitting still
- Chest pain or pressure
- Confusion, or unusual difficulty staying awake
- Blue or grey lips or face
- Symptoms that improved and then abruptly got worse
- An inability to keep fluids down, or signs of dehydration
- In someone with COPD or heart failure: a clear step down from their usual baseline
For an older adult, confusion deserves particular attention. In people over 70, a serious infection sometimes announces itself as new disorientation or a fall rather than a high fever. Family members notice it before the patient does. If an older relative suddenly seems muddled and isn’t normally, that’s a reason to be seen — not something to watch overnight.
One Note on Prevention
Everything above is about treatment after the fact. The cheaper version of this conversation happens before you get sick.
If you’re in any of the groups on that list and haven’t had this year’s flu vaccine, it’s not too late — flu season regularly runs into February and March. We give flu shots at every location, including the higher-dose formulation for adults 65 and older. If you’re 75 or older, or 50 to 74 with a heart or lung condition, the RSV vaccine is also worth asking about; we offer that here too.
Frequently Asked Questions
Is it too late for antivirals if I’ve been sick for three days?
Not necessarily. Flu antivirals work best when started within 48 hours of symptoms beginning, but for people at increased risk of complications, treatment is still recommended even when started later. The benefit is smaller, but it isn’t zero. Come in and let a provider assess it rather than deciding on your own that you’ve missed the window. For COVID, oral antiviral treatment is generally started within five days of symptom onset.
What counts as high risk for flu complications?
Adults 65 and older; anyone pregnant or recently postpartum; people with asthma, COPD or other chronic lung disease, heart disease, diabetes, kidney or liver disease, significant obesity, or neurological conditions affecting swallowing; anyone immunocompromised; and residents of long-term care facilities. Well-controlled conditions still count — managed asthma and managed diabetes are both on the list.
Do flu antivirals actually work?
In otherwise healthy adults, they shorten illness by around a day — real but modest. The stronger case is for people at higher risk of complications, where the goal isn’t faster symptom relief but a lower chance of the illness progressing to pneumonia or hospitalization. That’s why a provider may recommend treatment for one patient and not another with identical symptoms.
I take several medications. Does that affect COVID treatment?
It can, significantly. The oral COVID antiviral contains ritonavir, which changes how the body handles many common drugs including statins, blood thinners, and certain heart medications. These interactions are usually manageable, but only if your provider knows your full medication list — so bring it, including over-the-counter products and supplements. Never stop or change a medication on your own based on something you’ve read.
Can I get antivirals without being seen?
No. Antiviral medications are prescription treatments, and whether they’re appropriate depends on your symptoms, timing, medical history, and other medications. A provider needs to evaluate you first — which is part of why we’d rather you come in early than wait.
Should I still get a flu shot if I’ve already had flu this season?
Generally yes. Flu vaccines protect against multiple influenza viruses, and having had one strain doesn’t protect you from the others circulating later in the season. Ask a provider about timing relative to your illness.
My elderly parent seems confused but doesn’t have much fever. Is that concerning?
Yes, and it’s worth acting on. In older adults, serious infection can present as new confusion, unsteadiness, or a fall rather than a high temperature — the typical signs are sometimes muted. A sudden change in someone’s mental clarity who is normally sharp warrants prompt evaluation. If it comes with breathing difficulty, chest pain, or you can’t rouse them properly, go to an emergency room.
That’s the Series
Over five parts we’ve gone from sorting out which virus you’re dealing with, through this year’s vaccines and the unusual policy backdrop, to choosing between urgent care and an emergency room, the September sick cycle in kids, and now the people for whom timing matters most. Thanks for reading along.
Respiratory season runs through March. We’re here for all of it — seven days a week, five locations across Brooklyn and Queens. Walk in, or check in online and we’ll be ready for you.
