Choose cold and flu medicine by its active ingredients and warnings—not by the words on the front of the box. Decongestants such as pseudoephedrine can raise blood pressure, and ibuprofen or naproxen may also affect it. If your blood pressure is severe or uncontrolled, Mayo Clinic says not to take a decongestant; ask a clinician or pharmacist to review your specific symptoms, medicines, and health conditions before choosing an over-the-counter product.
Start with the symptoms you actually have
Combination cold and flu products can contain several active ingredients, even when the front label emphasizes just one symptom. The FDA’s Medicines In My Home: Adult printable version advises choosing a medicine for only the problems you have. A single-ingredient product—or a nonmedicine measure—can help avoid taking ingredients you do not need.
There is no brand that can be assumed safe for everyone with high blood pressure. Formulations and warnings can differ, so check the Drug Facts label every time, including when buying a familiar product.
Check congestion medicines for decongestants
Decongestants narrow blood vessels and can raise blood pressure. Mayo Clinic lists pseudoephedrine, ephedrine, phenylephrine, naphazoline, and oxymetazoline among ingredients to look for. Its guidance says people with severe or uncontrolled high blood pressure should not take a decongestant. The FDA also advises people with high blood pressure or heart disease to talk to a doctor before using one.

For a stuffy nose, Mayo Clinic suggests saline nasal spray as an alternative. The American Heart Association’s January 18, 2019 article also discusses nasal saline for congestion. If you are unsure whether a product is a decongestant or whether it is appropriate for you, ask a pharmacist or clinician before taking it.
Consider fever and aches separately
Mayo Clinic suggests considering aspirin or acetaminophen for fever, sore throat, headache, or body aches, and cautions that ibuprofen and naproxen may lead to high blood pressure. That is general guidance, not personal clearance: age, pregnancy, liver or kidney disease, allergies, other medicines, and package directions can change which option is appropriate. The sources cited here do not establish individualized doses.

Check every product for duplicate pain relievers. For example, a cold medicine may already contain acetaminophen; adding another product with the same ingredient can result in a dangerous amount. MedlinePlus warns against taking multiple products with the same pain reliever. Follow the label directions: the FDA educational material notes that using more acetaminophen than directed can damage the liver.
Use the label checklist before taking a product
- Read active ingredients and warnings. Look for decongestants and warnings for people with hypertension or those taking blood-pressure medicines.
- Check for duplicates. Compare the active ingredients in cold, flu, and pain medicines before combining them.
- Check sodium content. The American Heart Association notes that some over-the-counter medicines contain a lot of sodium. Its general guidance, on a page last reviewed in 2025, is less than 2,300 milligrams per day, with an ideal aim of less than 1,500 milligrams per day; these are general daily sodium targets, not medicine doses or individual instructions.
- Follow the product directions and limits. Do not exceed the label dose or combine products without confirming their ingredients.
- Have your specific choices reviewed. Show a pharmacist or healthcare professional the product label and your current prescription list, especially if your blood pressure is severe or uncontrolled.
Try comfort measures for other symptoms
For throat irritation, Mayo Clinic suggests warm salt-water gargling, warm water with lemon and honey, or menthol cough drops. For general comfort, it and MedlinePlus suggest fluids, rest, and increased humidity; MedlinePlus specifically mentions a cool-mist humidifier. These measures may ease symptoms but are not cures for a cold or influenza.

Keep taking prescribed blood-pressure medicine unless your clinician says otherwise
Do not stop or change prescribed blood-pressure medicine on your own because you have a cold or are considering an over-the-counter product. The American Heart Association’s Managing High Blood Pressure Medications guidance, last reviewed August 14, 2025, says not to stop prescribed medicines without speaking with a healthcare professional and recommends discussing over-the-counter medicines and supplements with them.
