When your baby wakes up screaming at 2am and your pediatrician's office doesn't open for six more hours, the last thing you want to be doing is Googling "is this medicine safe for babies?" while bouncing a miserable infant on your hip. I've been there — twice — and having the right medicines on hand (and knowing what they actually do) makes all the difference.
This is my go-to list of baby-safe medicines, what each one treats, and a few things I wish someone had told me before my kids got sick. I've listed generic drug names first, with brand names in parentheses, because store brands work just as well and your wallet will thank you.
One important note before we dive in: This list is intended for babies under one year old, not newborns. If your newborn is sick, call your pediatrician or go to urgent care. Newborns can go downhill fast, and you don't want to manage that at home. You're a smart parent – trust that instinct.
1. Infant Acetaminophen Drops (Tylenol)
This is the first medicine I'd tell any new parent to have on hand. It's a pain reliever and fever reducer that's safe for young infants, and it works. Dosage is based on weight, not age, so check with your pediatrician or use a weight-based dosing chart to get it right.
Note: don't use acetaminophen to treat a fever in a baby under 12 weeks old. Call your ped instead.
Money-saving tip: Since 2011, Children's Acetaminophen and Infant Acetaminophen have the same concentration. Buy the larger Children's bottle and dose by weight — it's cheaper and works the same.
2. Acetaminophen Suppositories
Nobody wants to use these, but the stomach bug will change your mind fast. When a baby is vomiting and can't keep anything down but also has a fever, suppositories are genuinely useful.
3. Infant Ibuprofen Drops (Motrin, Advil)
Ibuprofen is another effective pain reliever and fever reducer, and it lasts 6–8 hours compared to acetaminophen's 4–6 hours, which at 2 am feels like a gift. However, it's not safe for babies under 6 months old. Their livers aren't mature enough to metabolize it well, and some pediatricians prefer not to use it in younger infants because the longer-lasting effects can make it harder to assess how sick a baby actually is.
Like acetaminophen, dosage is weight-based. Some pediatricians recommend alternating ibuprofen and acetaminophen every 3 hours during a fever once you know the source. Check with yours before doing this because the dosing can get tricky, and you don't want to do it without a clear schedule written down.
Note: Do not give ibuprofen if your baby is dehydrated or vomiting, as this can affect kidney safety.
4. Simethicone Anti-Gas Drops (Mylicon, Little Remedies Gas Relief)
If your baby is clearly gassy – drawing their knees up, arching their back, inconsolable after feeds – simethicone drops can help move those gas bubbles along. Think of it as infant Gas-X. It's one of the gentler things on this list and generally well-tolerated.
5. Electrolyte Solution (Pedialyte, Infalyte)
The stomach bug is a rite of passage in our house every winter, and Pedialyte is the only reason we survived it. When your baby has vomiting and diarrhea, plain water isn't always enough – their body needs the right balance of water, sugar, and salt to rehydrate properly. They also come in freezer pop form which might be more appealing when you're feeling crummy from the barfs.
Doctor tip: When my son had a violent stomach bug and couldn't keep anything down, my doctor told me to give liquids in VERY small doses (like a tablespoon at a time) so he would be able to keep it down and his stomach wouldn't spasm and send it all back up.
6. Saline Nasal Spray
A stuffy nose is rough on a baby who can't breathe through their mouth while nursing or bottle-feeding. Saline spray thins the mucus, making it easier to clear. I also like the mist version but it comes down to which method your child will most likely tolerate – having something sprayed up their nose or something held on their face. (Historically, kids aren't a big fan of either.)
7. Nasal Aspirator (NoseFrida)
This is genuinely one of my favorite baby products ever invented. You place the tube at the base of the nostril and use your own suction – through your mouth – to draw out the mucus. I know how that sounds. There's a filter in the tube; you won't get a mouthful of snot. Babies tend to tolerate this much better than the old bulb syringe, and it actually works. Keep it near the saline spray and use them together.
If you're really not keen on a manual aspirator, I really like the Navage electric version.
8. Chest Rub (baby-safe formulas only)
Baby chest rubs work more like aromatherapy than actual medicine – the eucalyptus or menthol scent signals the brain that the airway feels more open, which can help a congested, fussy baby settle. Whether it's a placebo effect or not, I'll take anything that helps.
Important warning: Do not use any chest rub containing camphor (including regular Vicks VapoRub) on children under 2 years old. Camphor is toxic if ingested, and studies have shown it can actually inflame small airways and increase mucus production when inhaled – the opposite of what you want. Look for baby-specific formulas without camphor.
9. Cool-Mist Humidifier
Steam helps thin mucus, making it easier for a congested baby to breathe. I prefer cool-mist models over warm-mist because they're less likely to grow mold. Run it in the baby's room at night – congestion and cough almost always get worse when babies are lying down.
A note on elevation: When a baby is congested, it's really tempting to prop them up slightly to help them breathe more comfortably. Please don't. The AAP states that sleep surfaces inclined more than 10 degrees are unsafe for infant sleep and even a slight incline can cause a baby's heavy head to flop forward, cutting off their airway — a condition called positional asphyxia. The humidifier running in a flat, safe sleep environment is genuinely the better tool here.
10. Thermometer
Pediatricians will tell you: if you think your baby feels hot, they probably have a fever. You know your baby better than anyone. But at some point your ped is going to ask for a number, and you need a reliable thermometer to give them one.
The AAP considers rectal temperature the gold standard for accuracy in babies and for babies under 3 months, it's specifically what they recommend. Nobody loves it, but when accuracy matters most, it's the one to reach for.
As your baby gets older, a temporal artery (forehead) thermometer is the most practical everyday option — it works on all ages, is easy to use, and can even be used while baby is asleep. Ear thermometers are fine for babies over 6 months but aren't recommended for younger infants and Armpit readings are the least accurate of all, so treat those as a first pass only.
A few things worth skipping: pacifier thermometers and forehead strip thermometers aren't considered reliable, so save your money.
11. Medicine Dispensers
Most medications come with a dropper or dosing cup, but if your baby fights those, look for alternative dispensers that use pacifiers or bottle nipples to deliver medicine. The FridaBaby MediFrida Accu-Dose Pacifier Dispenser is a popular one. Fair warning: if the medicine tastes terrible, the pacifier is not going to save you.
A note on homeopathic medicines: I haven't included them here because evidence for their effectiveness is largely anecdotal. If you're curious, I've written about them separately — but I'd lean on the medicines above first.
The Bottom Line
Having the right medicines stocked before your baby gets sick is one of the best things you can do as a new parent. Remember: when in doubt, call your pediatrician. No question is too small when it comes to your baby's health, and that's exactly what they're there for.
