Carbon Monoxide After the Storm: The Symptoms Mistaken for the Flu

By the Jase Medical Team

The storm has passed, but the power is still out.

It’s raining, so the generator gets moved a little closer to the house—maybe under the porch or near an open garage. You’re making do, charging phones, keeping the refrigerator cold, trying to get through another day without power.

By day three, everyone feels terrible.

You’ve got a headache. Your spouse is nauseated. Someone feels weak and achy. Maybe the dog isn’t acting like itself either.

In February, it’s easy to think: The flu finally got us.

In July: Probably the heat. Maybe a stomach bug.

But there’s one question that should make you consider something entirely different:

Does everyone in the house feel sick at the same time—and do you start feeling better when you leave?

If the answer is yes, get everyone outside into fresh air and call 911. Carbon monoxide could be the reason.

Why Carbon Monoxide Can Look Like the Flu

Carbon monoxide (CO) is a colorless, odorless gas produced when fuels don’t burn completely. Generators, charcoal grills, vehicles, and other fuel-burning equipment can all produce it.

After storms and power outages, the risk increases because people start improvising.

A generator gets moved closer to the house because it’s raining. A grill gets pulled into a garage. A vehicle is left running in an enclosed or partially enclosed space.

The problem is that early carbon monoxide poisoning doesn’t necessarily look like poisoning.

It can cause headache, dizziness, weakness, nausea, vomiting, chest discomfort, and confusion.

Those symptoms overlap with plenty of ordinary illnesses.

That’s why the symptom list isn’t necessarily the most useful thing to remember.

The pattern is.

The Question That Can Break the Case Open

Imagine you’ve had a headache all morning.

You drive somewhere to pick up supplies and realize that after being away from the house for a while, you feel noticeably better.

You come home.

The headache returns.

Then you realize your spouse has a headache too. Someone else feels nauseated. The dog is unusually sluggish.

A virus can certainly spread through a household. But several people becoming sick at roughly the same time—and improving when they’re away from the same environment—is an important clue that the environment itself may be the problem.

Carbon monoxide exposure can affect multiple people sharing the same space.

So after a storm or during a power outage, remember this question:

Who else feels sick, and do we feel better when we leave?

If that pattern is present, don’t stay inside trying to determine whether it’s the flu, heat exhaustion, food poisoning, or carbon monoxide.

Get out.

A Normal Pulse Oximeter Doesn’t Rule Out Carbon Monoxide

This is an especially important misconception if you keep a fingertip pulse oximeter at home.

You feel terrible, put it on your finger, and see: 98%.

That can feel reassuring.

With suspected carbon monoxide poisoning, it shouldn’t.

A standard two-wavelength pulse oximeter cannot reliably distinguish normal oxygen-carrying hemoglobin from hemoglobin carrying carbon monoxide. As a result, the number displayed on a typical home pulse oximeter can appear normal even when significant carbon monoxide exposure has occurred.

A normal pulse ox reading does not rule out carbon monoxide poisoning.

If the circumstances and symptoms make you suspect CO, don’t use a reassuring-looking oxygen saturation number as a reason to stay inside.

What Should You Do If You Suspect Carbon Monoxide?

The immediate action is straightforward:

Get everyone out of the building and into fresh air. Then call 911.

Don’t remain inside looking for the source. Don’t wait to see whether the headache improves. Don’t rely on opening a window or door and staying in the home.

Emergency medical professionals can evaluate the exposure and provide oxygen and other treatment as appropriate.

If someone is confused, collapses, loses consciousness, has significant difficulty breathing, or is otherwise severely ill, treat it as an emergency.

And don’t forget everyone sharing the environment—including pets. If multiple members of the household seem unexpectedly sick at once, that’s part of the clue.

Generators Need Distance From the House

Generators are one of the most important carbon monoxide risks following storms.

They should be operated outdoors and away from the home, not inside a house, garage, basement, shed, carport, porch, or other enclosed or partially enclosed area.

Moving one “just under the porch” to keep it out of the rain can unintentionally move carbon monoxide closer to doors, windows, and vents where exhaust can enter the home.

The same principle applies to other fuel-burning equipment.

A charcoal grill doesn’t become safe to use indoors because the power is out. A vehicle shouldn’t be left running inside a garage to generate power or charge devices.

If it burns fuel, think about where the exhaust is going.

One of the Best Preparedness Tools Is Already on the Wall

There is a simple layer of protection that doesn’t require recognizing symptoms at all:

working carbon monoxide alarms.

Install CO alarms on every level of your home and outside sleeping areas, and make sure they’re functioning properly.

If an alarm sounds, move everyone outside and follow emergency guidance. Don’t assume it’s malfunctioning because nobody feels sick yet.

A CO alarm can identify the problem before your body has to.

Sometimes Preparedness Is Knowing Which Question to Ask

After a hurricane, tornado, winter storm, or extended power outage, there are plenty of things competing for your attention.

Is the refrigerator staying cold? Do you have enough fuel? When will the electricity come back? Is everyone hydrated? Can you get to the pharmacy?

Carbon monoxide doesn’t necessarily announce itself as a dramatic emergency. Sometimes it looks like a family that simply feels lousy on day three.

That’s why appropriate medical preparation isn’t just a shelf full of supplies.

Sometimes it’s knowing enough to notice when the story doesn’t fit.

At Jase Medical, we’re a family team of medical doctors, PAs, and pharmacists focused on that grey space—the moments when normal healthcare access and normal routines are disrupted, and knowing what to do next matters.

We’re not a replacement for primary care or emergency medicine.

We’d simply rather you recognize this pattern on day one:

If everyone in the house feels sick at the same time and starts feeling better when they leave, get out into fresh air and call 911.

Don’t let a normal pulse oximeter reading talk you out of it.

Why Patients Run Out of Meds: Ordinary Disruptions

By the Jase Medical Team

Most people who unexpectedly lose access to a prescription didn’t lose it in a hurricane.

A bottle gets left in a hotel room. A suitcase doesn’t make the flight. Medication disappears during a move. A prescription is stolen from a car. A house fire destroys everything in the medicine cabinet. Someone accidentally knocks a bottle into water and the medication can no longer be used.

These are ordinary disruptions, and there’s an important difference between them and a declared disaster: the healthcare system may have more emergency mechanisms available during the hurricane than it does on an ordinary Tuesday.

When there’s no disaster declaration or emergency order, replacing medication often comes down to your insurance plan’s own lost, stolen, or damaged medication policy. Those policies can be surprisingly limited.

That’s why the most useful preparation isn’t necessarily having more medication. It’s knowing who to call, what your plan allows, and having the information you’ll need when you make that call.

Does Insurance Replace Lost Medication?

Sometimes, but don’t assume that it will automatically.

Health plans and pharmacy benefit programs can have specific limits on how often they’ll authorize an early refill or replacement because medication was lost, stolen, or damaged. Depending on your coverage, there may be restrictions on how frequently an override is available or additional steps required before the replacement can be processed.

That means one of the simplest medication-preparedness questions you can ask today is:

“What is my plan’s policy if my medication is lost, stolen, or damaged?”

Call the member-services number on your insurance card or ask your pharmacist how your plan typically handles a lost-medication override. You don’t need to wait until something is missing to understand the process.

If your medication actually is lost or damaged, contact your pharmacy and insurance plan promptly. They can tell you what your specific coverage allows and whether your prescriber needs to become involved.

A Replacement May Not Mean Another Full Month

There’s another detail that can surprise people: replacing a lost prescription doesn’t necessarily mean receiving an entirely new month’s supply.

Depending on the medication, prescription, insurer, and circumstances, the replacement process may account for how much of the original supply should still have remained.

For example, if you’re halfway through a prescription when the remaining medication is lost, the replacement may be handled differently than if an unopened prescription disappears the day you pick it up.

The important point isn’t to calculate the replacement yourself. It’s not to assume that “replacement” automatically means starting the prescription cycle over.

Your pharmacist and insurance plan can explain how the remaining quantity will be handled in your particular situation.

If Your Medication Was Stolen, Document It

Losing medication and having medication stolen may trigger different requirements.

If you believe a prescription was stolen, contact your pharmacy and insurer and ask exactly what documentation they require. A police report may be required before an insurer or pharmacy can move forward with certain replacement requests.

If you’re instructed to file one, keep a copy or the report information somewhere accessible. Having that documentation ready can prevent another round of calls when you’re already trying to replace something you need.

And be precise when you explain what happened. “I lost my medication” and “my medication was stolen” may not be treated as the same situation.

Controlled Substances Follow Tighter Rules

If the medication you’ve lost is a controlled substance, don’t assume the same replacement process applies.

Controlled medications are subject to additional federal and state requirements, and the rules can vary based on the medication’s schedule and circumstances. A pharmacist may not be able to simply replace the medication or process an ordinary early refill.

If you’ve lost a controlled-substance prescription, contact your prescriber promptly as well as your pharmacy. Your prescriber may need to issue a new prescription or determine the appropriate next step.

Don’t try to compensate for missing medication by stretching, skipping, changing, or rearranging doses yourself. Ask the clinician managing the prescription what they want you to do while the situation is being resolved.

This is also worth discussing before you ever lose the medication. If you regularly take a controlled substance, ask your prescriber what process they want you to follow if it is ever lost, stolen, or destroyed.

Why a Declared Disaster Can Be Different

A major disaster doesn’t make medication access easy, but it can activate systems that aren’t necessarily available after an ordinary medication loss.

Depending on the disaster, location, insurance coverage, and emergency declarations in effect, additional mechanisms may become available to help people maintain access to necessary prescriptions. Government programs, insurers, pharmacies, and state authorities may implement temporary policies designed specifically for affected communities.

That’s an important distinction.

A suitcase lost during an ordinary vacation and a medicine cabinet destroyed during a federally declared hurricane may leave you with the same practical problem – your medication is gone – while putting you into very different administrative systems for replacing it.

So don’t assume advice you read about emergency refills during hurricanes automatically applies when medication disappears during an ordinary week. Start with your pharmacist, insurance plan, and prescriber and ask what applies to your specific situation.

Keep One Medication Record You Can Grab Anywhere

Regardless of why medication goes missing, one simple piece of preparation makes almost every conversation easier: keep a current medication list.

For each prescription, record the medication name, dose, prescriber, and pharmacy. If you take several medications, keep the list somewhere you can access without relying entirely on a patient portal or pharmacy app.

That record isn’t a replacement prescription, but it gives the people helping you a much better starting point. If you’re standing at an unfamiliar pharmacy after losing your suitcase, calling an insurance company after a house fire, or trying to reach a prescriber about a controlled medication, you don’t want to reconstruct your medication history from memory.

This is one of the simplest forms of appropriate medical preparation because it costs nothing and doesn’t require accumulating additional medication. You’re preparing the information, not stockpiling the prescription.

Know the Process Before You Need It

At Jase Medical, we’re a family team of medical doctors, PAs, and pharmacists focused on appropriate medical preparation: understanding where normal healthcare access can break down and making clinically responsible plans before it does.

And sometimes the disruption isn’t dramatic at all. It’s a suitcase that didn’t arrive, a bottle damaged at home, a prescription stolen from a car, or a house fire that never makes the national news.

We’re not a replacement for primary care, your pharmacist, or your insurance plan. In this situation, those relationships are exactly what you need. We would simply rather you understand the process on a normal week than learn it while standing at the pharmacy counter without the medication you depend on.

So if you take regular prescriptions, do two things now: keep a current record of your medications, doses, prescribers, and pharmacy, and find out how your insurance plan handles medication that is lost, stolen, or damaged.

Because medication preparedness isn’t only about hurricanes, evacuations, or widespread emergencies. More often, it’s about being ready for the ordinary disruption you never expected to become a medical problem.

The Drug Interactions You Create in an Emergency

By the Jase Medical Team

Most of the time, you don’t have to think very hard about drug interactions. Your doctor has your medication list. Your pharmacy has it too. When a new prescription comes through, software checks it against the medications already on file, and your pharmacist reviews the combination and steps in when something doesn’t look right.

Then the storm hits.

Your usual pharmacy is closed. You’re buying cold medicine at a grocery store two towns over. Maybe you’re dealing with an injury, respiratory illness, allergies, or another problem on top of the four or five prescriptions you already take every day. Suddenly, the drug-interaction check stops being software and becomes a person. And that person may be you.

The good news is that you don’t need to memorize a database of drug interactions to prepare for that possibility. For most people, there are two much more practical things to do: learn to spot duplicate ingredients in common over-the-counter medications, and have one conversation with your pharmacist about the prescriptions you already take.

First: Watch for the Same Ingredient in More Than One Product

One of the easiest medication mistakes to make during a stressful week doesn’t look like a drug interaction at all. You have a headache and fever, so you take acetaminophen. Later, your congestion gets worse, so you reach for a multi-symptom cold and flu product. That night, you consider something marketed for nighttime symptoms.

The problem is that more than one of those products may contain acetaminophen.

Acetaminophen appears in many over-the-counter cold and flu products, combination pain relievers, nighttime formulas, and some prescription pain medications. That means it’s possible to take the same active ingredient from multiple products simply because each package has a different name and purpose.

During an emergency, you’re probably not shopping for something labeled simply “acetaminophen.” You’re shopping for “Cold + Flu,” “Severe,” “Nighttime,” or “Pain Relief.” Those names describe what the product is marketed to treat, but they don’t necessarily make it obvious what’s actually inside.

Before combining over-the-counter medications—or taking one alongside a prescription medication—turn the package around and look at the Active Ingredients section. If you see acetaminophen listed in more than one product you’re considering, stop and ask a pharmacist or another qualified healthcare professional before combining them.

The goal isn’t to start calculating or rearranging doses yourself. It’s simply to know what’s actually in what you’re taking.

A Disaster Adds Medications to a List You Already Had

Think about what happens medically during an ordinary bad week after a storm. Someone hurts their back clearing debris and wants a pain reliever. Someone develops a respiratory illness and reaches for cold medicine. Someone gets stung or develops a rash and considers an antihistamine. Someone develops an infection and is prescribed an antibiotic.

None of those situations is particularly unusual. But those new medications aren’t entering an empty medicine cabinet. They’re being added to the blood pressure medication, anticoagulant, diuretic, psychiatric medication, heart medication, diabetes medication, or other prescriptions someone was already taking before the storm arrived.

That’s where the interaction question lives: between what you already take and what the disruption adds.

Under normal circumstances, several layers of the healthcare system help catch those potential problems. Your medical record contains your prescriptions. Your regular pharmacy knows what it has dispensed. Pharmacy software flags potential interactions. A pharmacist can review the combination before handing you the medication.

During a disruption, some of those layers may disappear. You may be using a different pharmacy, buying an over-the-counter medication somewhere that doesn’t have your prescription history, or receiving care from a clinician who has never seen you before.

The Emergency Can Change More Than Your Medication List

There’s another reason medication safety can become more complicated during a disaster: your body and circumstances may be different too.

You may be spending hours working outside in the heat, drinking less because clean water is limited, dealing with vomiting or diarrhea, or eating very differently than usual. At the same time, access to routine lab work, follow-up appointments, and medication monitoring may be interrupted.

A medication combination isn’t used in a vacuum. Your hydration, health conditions, and other medications all matter. That’s why a combination you’ve taken without problems under ordinary circumstances shouldn’t automatically be assumed to be problem-free when new medications and unusual physical stressors are added.

This doesn’t mean you need to understand every possible interaction yourself. It means the person helping you make a medication decision needs to see the whole picture.

Your Medication List Is Part of That Picture

We’ve said this before at Jase, but this is one more reason to keep a current written medication list. For each prescription, include the medication name, dose, prescriber, and pharmacy, and keep that information somewhere you can access even if your phone is dead, the patient portal isn’t loading, or you’re standing in a pharmacy that has never filled a prescription for you before.

That list isn’t only there to help you remember what you take. It gives a pharmacist or clinician the information they need to check what you’re about to add against what’s already there.

Your regular pharmacy computer may have been quietly helping catch these interactions for years. It can’t do that for you from a parking lot.

Ask Your Pharmacist One Question Before the Storm

The best time to discover an important medication interaction isn’t while you’re sick, evacuated, or trying to find an open pharmacy. The next time you have an appropriate opportunity to speak with your pharmacist, bring your current medication list and ask:

“If I end up needing an antibiotic or a pain reliever during an emergency, are there any of my regular medications that I need to be especially careful about combining with them?”

Then write down what they tell you somewhere you can find it during an emergency.

You don’t need to become your own pharmacist or memorize every possible combination. You simply want to know where the potential trouble spots are in your medication list so that, if normal systems aren’t available, you know when you need to stop and get professional guidance rather than guessing.

Appropriate Medical Preparation Includes What You Already Take

Emergency medical preparation often focuses on what you might need to add: wound supplies, contingency medications, pain relievers, cold medicine, or other essentials. But preparedness also means understanding how those things fit alongside the medications already keeping you healthy.

At Jase Medical, we’re a family team of medical doctors, PAs, and pharmacists focused on appropriate medical preparation—clinically grounded readiness for the moments when normal healthcare access becomes harder to reach. We’re not a replacement for primary care or your pharmacist. In fact, this is exactly why we want them in the conversation before you need the backup plan.

So before the next storm or disruption, read the active ingredients before combining medications, and ask your pharmacist which common additions could cause problems with the prescriptions you already take.

Because during an emergency, the safest medicine cabinet isn’t necessarily the one with the most medication in it. It’s the one where somebody has already checked how the pieces fit together.
