When you’re sick with a cold, flu, or stomach bug, having the right supplies at home can make the difference between a miserable few days and a manageable recovery. You likely need a combination of fever reducers, throat soothers, fluids, and a few basic tools to monitor your symptoms. Here’s a practical breakdown of what to stock up on, whether you’re building a sick-day kit in advance or sending someone to the store right now.
Fever and Pain Reducers
The two most useful over-the-counter options are acetaminophen (Tylenol) and ibuprofen (Advil, Motrin). Both lower fever and ease body aches, headaches, and sore throat pain. If one alone isn’t keeping your fever down, you can alternate between the two: take one first, then switch to the other four to six hours later, cycling every three to four hours as needed. Don’t take both at the same time. For adults, stay under 4,000 milligrams of acetaminophen and 1,200 milligrams of ibuprofen per day. If you’re alternating them for more than three days, it’s worth checking in with a healthcare provider.
Cold and Flu Symptom Relief
Beyond fever reducers, a few targeted products can address the worst of your symptoms:
- Nasal decongestant: Pseudoephedrine (sold behind the pharmacy counter) is the most effective oral decongestant for a stuffed nose. Nasal sprays containing oxymetazoline work faster but shouldn’t be used for more than three consecutive days, or the congestion can rebound and get worse.
- Cough suppressant: Look for products containing dextromethorphan (often labeled “DM”) if a dry cough is keeping you up at night. It won’t cure the cough, but it quiets the reflex enough to let you sleep.
- Sore throat relief: Throat lozenges with menthol provide temporary numbing. A simple honey-and-warm-water mixture works surprisingly well too, and honey has mild antimicrobial properties.
- Antihistamine: Diphenhydramine (Benadryl) can help with a runny nose and sneezing, and its drowsiness side effect becomes an advantage at bedtime.
Many combination products (like DayQuil or NyQuil) bundle several of these ingredients together. That’s fine, but read the label carefully. If a combo product already contains acetaminophen, don’t take extra acetaminophen on top of it. Doubling up is one of the most common accidental overdose scenarios.
Zinc Lozenges
Zinc is one of the few supplements with real evidence behind it for colds. A meta-analysis of three randomized trials found that dissolving zinc acetate lozenges throughout the day (providing roughly 80 to 92 milligrams of elemental zinc daily) improved recovery rates. The catch is timing: you need to start within 24 hours of your first symptoms. The typical routine is one lozenge every two to three hours while awake, letting each dissolve slowly in your mouth rather than chewing or swallowing it. Zinc taken after a cold is well established won’t do much.
Fluids and Electrolytes
Dehydration makes almost every symptom feel worse. Fever, sweating, and reduced appetite all pull fluid out of you faster than usual. Stock up on more than just water:
- Electrolyte drinks: Pedialyte, Liquid IV, or similar oral rehydration solutions replace the sodium and potassium you lose through sweat and, if you have a stomach bug, through vomiting or diarrhea. Sports drinks like Gatorade work in a pinch, though they contain more sugar.
- Broth: Chicken or vegetable broth provides sodium, warmth, and a small amount of calories when eating feels impossible. Warm liquids also help loosen nasal congestion.
- Herbal tea: Chamomile or ginger tea can soothe a sore throat and settle nausea. Add honey for extra throat coating.
If you have a stomach virus specifically, don’t force yourself onto a restricted diet. Research from the National Institute of Diabetes and Digestive and Kidney Diseases shows that limiting what you eat doesn’t help you recover faster from viral gastroenteritis. Once your appetite returns, go back to your normal diet, even if diarrhea hasn’t fully resolved.
Easy Foods to Keep on Hand
When your appetite does come back, you’ll want foods that don’t require much effort to prepare and sit well in a fragile stomach. Crackers, toast, bananas, applesauce, and rice are classics for a reason: they’re bland enough to stay down and provide quick energy. Canned soup (especially broth-based varieties) is worth keeping in the pantry year-round for exactly this scenario. Oatmeal, scrambled eggs, and yogurt are slightly more substantial options once you’re past the worst of it.
Medical Tools Worth Having
A digital oral thermometer is essential. It’s the only way to know whether you actually have a fever versus just feeling feverish. Skip mercury and glass models entirely. A basic digital thermometer costs a few dollars and gives you a reading in under a minute.
A pulse oximeter, the small clip that goes on your fingertip, measures your blood oxygen level. This became a household staple during COVID, and it’s still useful for any respiratory illness. Normal oxygen saturation runs between 95% and 100%. If yours drops below 92%, that’s a signal to get medical attention. You can find reliable pulse oximeters at any pharmacy for around $20 to $30.
Comfort Items That Actually Help
A cool mist humidifier adds moisture to dry indoor air, which soothes irritated nasal passages and makes breathing easier while you sleep. The American Academy of Pediatrics recommends cool mist over warm steam vaporizers because vaporizers pose a burn risk if knocked over. Either type works for adding humidity, but cool mist is the safer choice, especially if children are in the home. Clean the humidifier daily with water and white vinegar to prevent mold and bacteria from building up inside.
Other small things that make a big difference: a box of soft tissues with lotion (your nose will thank you after two days of blowing), saline nasal spray to rinse out congestion without medication, and cough drops by the bed. A heating pad can ease the body aches that come with the flu, and an extra pillow to prop yourself up at night helps with post-nasal drip.

Signs You Need More Than Home Care
Most colds and even the flu resolve on their own within a week or two. But certain symptoms signal something more serious. A fever above 104°F (40°C) warrants a call to your doctor. Difficulty breathing, chest pain or pressure, confusion, persistent vomiting that prevents you from keeping fluids down, or symptoms that improve and then suddenly worsen all deserve prompt medical attention. If you’re using a pulse oximeter and your oxygen level stays below 92%, don’t wait to see if it improves on its own.
