Why blood pressure and cholesterol tablets are so common

High blood pressure and high cholesterol often do not cause pain, but over many years they can increase the risk of heart attacks, strokes and other problems. That is why they are sometimes called “silent risks”.

Medicines for blood pressure and cholesterol are not a sign that you have “failed”. They are tools your team can use, alongside lifestyle changes, to lower your future risk. For many older adults, the aim is not perfection – it is to gently tilt the odds in your favour.

Big picture: what these medicines are trying to do

In very simple terms:

• Blood pressure medicines help your heart and blood vessels work under less pressure, so there is less strain on the system.
• Cholesterol medicines help reduce harmful fats in the blood (especially “bad” cholesterol) and, in some people, lower the chance of clots and artery blockages.

The exact mix and dose of tablets is different for everyone. Your team will usually look at your overall risk – age, blood pressure, cholesterol, diabetes, smoking history, weight, family history and past heart events – rather than just one number.

Common blood pressure medicine groups (plain English)

Below are some of the main “families” of blood pressure medicines your team might mention. The exact name on your box may be different, but this can help you understand the type of tablet you are on.

1. ACE inhibitors – helping blood vessels relax

These medicines help blood vessels relax and widen, so blood flows more easily and pressure falls. They can also support the heart after some types of heart damage.

Possible common issues can include:

• A dry cough in some people.
• Occasional dizziness, especially when starting or increasing the dose.
• Effects on kidney tests or potassium levels, which is why blood tests are checked.

If you notice side effects, do not simply stop – speak to your GP or nurse. There are often alternative options.

2. ARBs – “cousins” of ACE inhibitors

ARBs work on a similar system to ACE inhibitors but in a slightly different way. They are often used when someone needs this type of medicine but cannot tolerate an ACE inhibitor, for example because of a persistent cough.

They may still affect kidney function or potassium, so blood tests are usually checked regularly.

3. Calcium channel blockers – easing the squeeze

These medicines help the muscle in the walls of blood vessels relax, so the vessels are less “tight”. They can lower blood pressure and may also be used for some types of angina.

Some people notice:

• Swollen ankles.
• Flushing or headache when starting.
• Constipation with certain types.

Many of these effects settle, but if they are troublesome it is worth telling your team – small changes in dose or type can sometimes help.

4. Diuretics – “water tablets”

Diuretics help your body get rid of extra fluid and salt through the kidneys. This can lower blood pressure and reduce swelling or breathlessness in some conditions.

Because they affect fluid and salts, you may need:

• Regular blood tests to check kidney function and salt levels.
• Clear advice on how much fluid and salt is right for you.

If you feel light-headed, very thirsty or notice big changes in how much you pass urine, let your GP or nurse know.

5. Beta blockers – slowing and steadying the heart

Beta blockers can slow the heart and reduce how hard it has to work. They may be used for blood pressure, angina, some rhythm problems and after certain heart events.

Some people find:

• Their pulse feels slower.
• They feel more tired, especially at first.
• Hands and feet may feel colder.

These tablets are usually started and adjusted gradually. Never stop them suddenly without medical advice, as this can sometimes be unsafe.

Common cholesterol medicine groups (plain English)

Cholesterol medicines are mainly about reducing future risk of heart attacks and strokes, rather than making you “feel better” day to day. That can make it harder to see the point – so understanding their aim is important.

1. Statins – lowering “bad” cholesterol and risk

Statins are the most commonly used cholesterol tablets. They reduce the amount of cholesterol your liver makes, and in many people they lower the chance of heart attacks and strokes.

Some people worry a lot about statin side effects. It is true that:

• Some people notice muscle aches or weakness.
• Liver blood tests are often checked when you start or change dose.
• Not everyone benefits to the same degree – your overall risk matters.

However, many people take statins for years with little trouble. If you have worries or side effects:

• Do not stop suddenly on your own.
• Write down what you notice – when it started, how it feels.
• Book a review with your GP, nurse or pharmacist to weigh up risks and benefits for you.

2. Ezetimibe and other add-on tablets

If statins alone do not bring cholesterol to the target your team is aiming for, or you cannot manage a higher statin dose, other tablets such as ezetimibe may be added. These can reduce how much cholesterol is absorbed from the gut.

These are usually considered in people with higher risk, or where cholesterol is still high despite changes and statins. Your team will explain why they are suggesting them.

3. Injectable treatments (for some higher-risk patients)

For a smaller number of people with very high cholesterol or strong family histories, specialist teams may offer injectable medicines that lower cholesterol in different ways. These are usually prescribed by hospital teams and are not needed for most people.

If you are offered these, you should be given time to ask questions and understand how they fit into your overall plan.

Talking about side effects without feeling guilty

Many older adults feel they must “put up with” side effects to avoid wasting NHS time, or they feel afraid their doctor will be annoyed if they raise concerns. In reality:

• Clinicians expect some people to have side effects – it is part of normal practice.
• They would rather you talk to them than quietly stop tablets at home.
• There are often choices: lower doses, different timings, different tablets, or sometimes accepting a slightly higher risk if the side effects are severe.

A useful sentence might be: “I understand this tablet is meant to help my heart in the long term. I am also finding these side effects hard. Can we look at the options together?”

Why medicines are often “for the long term”

It can feel unfair to be told that blood pressure or cholesterol tablets are likely to be “for life”. But the risk from high blood pressure and cholesterol also builds up over years. Stopping treatment too soon can undo some of the protection.

Long-term does not have to mean “never reviewed”. It is reasonable to ask:

• How often your medicines will be checked.
• Whether your doses still make sense as you age.
• Whether tablets can be simplified to make taking them easier.

As people get older, the balance between benefits and side effects may change. That is why regular reviews matter, especially if you are feeling more frail or have had falls.

Tablets and lifestyle: it is not either/or

Some people feel they have “failed” if they need tablets, or they are told to change their lifestyle as if tablets were not enough. In reality:

• Mild improvements in food, movement and smoking can work alongside medicines, not instead of them.
• Tablets can give you the energy and safety to do a bit more walking or gentle exercise.
• Changing lifestyle can sometimes allow doses to be lower – but this is always an individual decision with your team.

You do not have to choose between “being a good patient who takes tablets” and “being a healthy person who does it all naturally”. Most people live somewhere in the middle.
