People with high blood pressure (hypertension) may find that even a simple cough or cold is a big health problem. Many cough and cold medicines that you can buy without a prescription (OTC) have ingredients that can raise blood pressure, make medications less effective, or make heart health worse.
So, picking the right cough medicine is very important for staying safe and comfortable. This full guide looks at which cough medicines are safe for people with high blood pressure, which ones to stay away from, and natural alternatives that help with symptoms without raising blood pressure.
Why cough medicines can be bad for people with high blood pressure
Over-the-counter cough medicines work quickly, but they aren’t always safe for everyone. Decongestants are found in many cough medicines. They work by narrowing blood vessels to help with nasal congestion. Sadly, this also raises blood pressure and heart rate, which makes them dangerous for people with high blood pressure.
Some common things that can raise blood pressure are:
- Many cold and flu medicines contain pseudoephedrine.
- Phenylephrine is another common decongestant that can make your blood pressure go up.
- Ephedrine or Naphazoline are common ingredients in nasal sprays and oral cold medicines.
- NSAIDs (like ibuprofen and naproxen) can hold onto sodium and water, which raises blood pressure.
- Syrups with a lot of sodium: Some cough medicines in liquid form have a lot of sodium, which makes high blood pressure worse.
The American Heart Association (AHA) says that these ingredients narrow blood vessels and can make blood pressure medications less effective, which puts more stress on the heart.
Things to Stay Away From in Cough and Cold Medicines
Always read the labels on medicines carefully if you have high blood pressure. If you have high blood pressure, the following ingredients are not safe or are very likely to cause problems:
Unsafe Ingredient: Pseudoephedrine Reason to Avoid: Constricts blood vessels, which raises blood pressure and heart rate.
Phenylephrine Raises blood pressure and makes your heart race.
Ibuprofen and naproxen can hold onto water and raise blood pressure.
Syrups with sodium in them Add too much salt
Drugs that combine “D” or “CF” They often have decongestants in them, like Mucinex D and Claritin-D.
If you’re not sure, stay away from any medicine that has the letters “D” or “CF” on the label. These letters usually mean that the medicine has a decongestant in it.
Cough Medicines That Are Safer for People with High Blood Pressure
There are a number of safe and effective cough medicines for people with high blood pressure, which is a good thing. These choices help with symptoms without raising blood pressure.
1. Cough suppressants that contain dextromethorphan
This ingredient stops the brain from making you cough. It doesn’t narrow blood vessels or raise blood pressure, so it’s usually safe for people with high blood pressure.
For example:
- Delsym Cough Medicine
- Robitussin CoughGels (not D)
- Vicks Formula 44
2. Guaifenesin (an expectorant)
Guaifenesin can help loosen mucus in your chest or cough, which makes it easier to clear your airways. It is safe for people with high blood pressure because it doesn’t have any decongestant effects.
For example:
- Mucinex (not “Mucinex D”)
- Robitussin for Chest Congestion
3. The Coricidin HBP Range
People with high blood pressure should only use Coricidin HBP. These formulas don’t have decongestants in them, and they can help with a variety of symptoms, such as cough, cold, and flu.
For example:
- Cough and Cold Coricidin HBP
- Coricidin HBP for a cough and stuffy chest
4. NyQuil formulas for high blood pressure
Some kinds of NyQuil are sold as “HBP safe,” which means they don’t have any ingredients that raise blood pressure. These work well for nighttime relief without putting your heart at risk.
5. Natural Ways to Relieve Coughs That Are Safe for High Blood Pressure
If you don’t want to take medicine or prefer natural methods, there are a number of safe home remedies that can help with cough symptoms:
- Honey and warm water: This helps the throat feel better and stops coughing.
- Inhaling steam: This is a natural way to clear mucus and ease congestion.
- Gargling with saltwater helps soothe an irritated throat.
- Ginger, liquorice root, and peppermint teas are all good for calming coughs.
- Humidifier: Keeps the air moist so your throat doesn’t get dry.
These natural choices not only help your lungs stay healthy, but they also keep your blood pressure from going up.
How to Use Cough Medicine Safely if You Have High Blood Pressure
Follow these expert tips to make sure you stay safe while treating cough and cold symptoms:
- Before taking any over-the-counter medicine, talk to your doctor or chemist.
- Look at the labels of all the products you buy to see what the active ingredients are.
- Don’t use combination medicines; instead, look for medicines that only treat one symptom.
- Check your blood pressure often while you’re sick.
- Drink enough water to naturally loosen mucus.
- Get enough sleep; stress and tiredness can also raise blood pressure.
- Don’t eat salty foods or drink coffee while you recover.
Keep in mind that every person’s health is different, even if a cough medicine says it is “safe.” Before taking any medicine, always talk to a doctor.
How Being Sick Affects Blood Pressure
It’s important to remember that both illness and infection can raise blood pressure on their own. When your body fights off a cold or cough, stress hormones like adrenaline can go up for a short time, which can cause your blood pressure to rise. This is normal, but it shows how important it is to pick medicines that are safe for BP so the condition doesn’t get worse.
People who already have heart problems, kidney disease, or diabetes should be extra careful because even small changes in blood pressure can affect heart health over time.
