Key takeaways
Many cold medicines contain decongestants or nonsteroidal anti-inflammatory drugs (NSAIDs) that can raise blood pressure and should be avoided.
Acetaminophen, saline nasal sprays, expectorants, antihistamines, and Coricidin HBP products may be safer options for people with high blood pressure.
Always check product labels for hidden ingredients and ask a pharmacist or healthcare provider if you’re unsure what’s safe to take.
Having a cold is never easy, but it can get more complicated for people with high blood pressure (hypertension). Many over-the-counter (OTC) medicines, especially decongestants, can actually worsen blood pressure or heart problems. Fortunately, some products are made for those with hypertension who need quick symptom relief. If you have high blood pressure, you’ll want to read the drug labels and know which ingredients to skip. That way, you can avoid even bigger health problems while managing a cold.
Cold medicine ingredients: What’s safe vs. what to avoid with high blood pressure |
|
|---|---|
| Ingredients that are generally safe | Ingredients to avoid (unless otherwise directed by your healthcare provider) |
| Acetaminophen | Pseudoephedrine |
| Guaifenesin | Phenylephrine |
| Dextromethorphan | Ibuprofen |
| Saline nasal spray or rinse | Naproxen |
| Chlorpheniramine or loratidine | Combination cold medicines containing decongestants |
What cold medicine is safest for high blood pressure?
The safest cold medicines for people with high blood pressure are those that do not contain decongestants such as pseudoephedrine or phenylephrine. Safer options include acetaminophen for pain or fever, guaifenesin for chest congestion, dextromethorphan for cough, a saline nasal spray for congestion, and some Coricidin HBP products.
It’s also best to avoid NSAIDs, like ibuprofen and naproxen, when you have high blood pressure, since they can raise blood pressure and increase the risk of kidney problems. Even if your blood pressure is controlled with medication, it’s still a good idea to consult a healthcare provider before taking any decongestants.
Safer options may include the following:
- Acetaminophen: This is usually the preferred option for relieving pain or lowering fever for people with hypertension. However, while the risk of high blood pressure may be lower with acetaminophen, one study suggests that high doses (4,000 mg per day) may increase blood pressure in some people.
- Saline nasal sprays: These can help clear stuffy or runny noses by rinsing the nasal passages without the risks of oral decongestants. Brands like Simply Saline or Ocean are common options.
- Dextromethorphan: This cough suppressant may help calm the coughing reflex and is generally considered safe for those with high blood pressure. It’s often found in products like Delsym and Robitussin DM. Avoid taking dextromethorphan with monoamine oxidase inhibitors (MAOIs) like selegiline and tranylcypromine due to the risk of severely high blood pressure.
- Guaifenesin: This is an expectorant that helps loosen mucus, so it’s easier to cough up. It’s often combined with dextromethorphan in products like Mucinex DM.
- Antihistamines: These don’t increase blood pressure, but they’re less effective for cold symptoms than they are for allergies. One review found they may offer small benefits during the first couple days of a cold, but the benefits came from older sedating antihistamines like chlorpheniramine rather than newer ones like loratadine and cetirizine.

Why are some medications risky for people with high blood pressure?
It can be tempting to purchase anything that claims to promise fast relief from common cold symptoms. However, for people with high blood pressure, it’s not just about what works; it’s also about what could make things worse.
Decongestants
Some cold medications may contain decongestants or NSAIDs that can increase blood pressure and heart rate. While decongestants can narrow blood vessels in the nasal passages to reduce congestion, they can also tighten blood vessels throughout other parts of the body. Even decongestant nasal sprays, which are less likely to affect the whole body, still carry a warning about an increased risk of high blood pressure.
Examples of decongestants include:
- Sudafed (pseudoephedrine)
- Sudafed PE (phenylephrine)
- Dristan (oxymetazoline)
- Vicks Sinex (oxymetazoline)
- Afrin (oxymetazoline)
- Neo-Synephrine (phenylephrine)
NSAIDs
Other ingredients, like NSAIDs, can cause the body to hold on to salt and water, which may increase blood pressure or put extra stress on the heart. Even if you normally have your blood pressure under control with blood pressure medication, taking NSAIDs might make your medicine less effective.
- Advil, Motrin (ibuprofen)
- Aleve, Naprosyn (naproxen)
- Celebrex (celecoxib)
- Voltaren (diclofenac)
- Lodine (etodolac)
- Indocin (indomethacin)
- Feldene (piroxicam)
Aspirin is the exception. A meta-analysis of more than 20,000 people with hypertension found that aspirin did not have a significant effect on blood pressure. Therefore, most people on low-dose aspirin should keep taking it even with a cold. However, high-dose aspirin over extended periods could still carry a risk.
It’s important to read the labels on any products you use, as some combination medications marketed for multi-symptom control may contain these ingredients. If you’re not sure, ask a pharmacist or healthcare provider before taking anything new.
Natural cold remedies for people with high blood pressure
Many people with high blood pressure who are experiencing a cold may want to avoid OTC medications altogether. Some natural cold remedies can help relieve cold symptoms without increasing blood pressure. However, like OTC medications, they’re meant to manage symptoms rather than cure a cold.
- Warm fluids: Drinking warm liquids, such as tea, broth, or hot water with lemon, can help soothe a sore throat and thin mucus. However, you’ll want to watch for excessive salt intake from broths that can worsen high blood pressure.
- Rest: Allowing your body to rest can help it fight off a virus more effectively. Try to get extra sleep and take it easy while symptoms are at their worst.
- Honey: A spoonful of honey may help calm a cough and coat a scratchy throat. It’s a safe option for adults and older children, though it shouldn’t be given to babies under 1 year old due to the risk of infant botulism.
- Humidifiers: Adding moisture to the air can relieve nasal congestion, dry throat, and coughing. Cool-mist humidifiers work best when cleaned regularly to prevent mold.
- Steam: Breathing in steam from a warm shower or bowl of hot water may help open nasal passages and relieve sinus pressure. Just be careful not to get too close to hot water to avoid burns.
Natural remedies may be a helpful part of cold care routines for those trying to avoid OTC products that might interfere with blood pressure control. However, some natural supplements may increase blood pressure, such as ephedra and licorice root, so it’s best to avoid those.
Bottom line
The best cold medicine for high blood pressure avoids ingredients like pseudoephedrine, phenylephrine, ibuprofen, and naproxen that can increase blood pressure or interfere with blood pressure medications. Products containing acetaminophen, guaifenesin, dextromethorphan, or saline nasal spray are often safer choices. When shopping for multi-symptom cold medicine, always read the Drug Facts label or ask a pharmacist if you’re unsure.
Frequently asked questions
What should I do if my blood pressure goes up after taking cold medicine?
Stop using the product and check the label to see if it contains an ingredient like a decongestant or an NSAID. Then, recheck your blood pressure in a few hours. Call your healthcare provider if blood pressure stays high, and get medical help for chest pain, a severe headache, or trouble breathing.
Can I take DayQuil if I have high blood pressure?
Regular Vicks DayQuil Cold & Flu products may contain a decongestant that can cause harm if blood pressure is not controlled. Vicks DayQuil HBP Cold & Flu is a version that doesn’t contain decongestants and is made for people with high blood pressure.
Is Mucinex safe for high blood pressure?
Plain Mucinex and Mucinex DM products are decongestant-free and are generally safe for people with high blood pressure. However, Mucinex D, which contains pseudoephedrine, and other Mucinex products that contain NSAIDs may need to be avoided.
