Your Health Profile
If you're taking Benicar (olmesartan) for high blood pressure, you might be wondering if there’s a better option. Maybe your doctor suggested switching, or you’re noticing side effects. Maybe you’re just curious if another medication could work just as well-or better-for less money. You’re not alone. Thousands of people in the UK and beyond ask this same question every year.
What is Benicar (Olmesartan)?
Benicar is the brand name for olmesartan, an angiotensin II receptor blocker (ARB) used to treat high blood pressure. It works by blocking a hormone called angiotensin II, which normally causes blood vessels to tighten. By blocking this effect, olmesartan helps blood vessels relax, lowering blood pressure.
It’s usually taken once a day, with or without food. The typical starting dose is 20 mg, though some people need 40 mg daily. It’s not a cure-it’s a long-term control medication. You won’t feel different after taking it, but your blood pressure numbers will drop over time.
Olmesartan is also available as a generic, which costs significantly less than the brand-name version. In the UK, generic olmesartan is widely prescribed on the NHS and is just as effective as Benicar.
Why Consider Alternatives to Benicar?
Not everyone tolerates olmesartan well. Common side effects include dizziness, fatigue, and stomach issues like diarrhea or nausea. In rare cases, it’s been linked to severe intestinal problems-like sprue-like enteropathy-which can cause chronic diarrhea and weight loss. If you’ve had these symptoms, your doctor may want to switch you.
Cost is another factor. While generic olmesartan is affordable, some alternatives might be cheaper, especially if you’re paying out of pocket or have limited prescription coverage.
And then there’s effectiveness. Some people respond better to one class of blood pressure drugs than another. What works for your neighbour might not work for you. That’s why comparing options matters.
Top Alternatives to Benicar (Olmesartan)
There are several well-established alternatives to olmesartan. They fall into three main groups: other ARBs, ACE inhibitors, and calcium channel blockers. Each has pros and cons.
Other ARBs (Angiotensin II Receptor Blockers)
These work the same way as olmesartan but have slightly different chemical structures. That can mean different side effects or better tolerance for some people.
- Losartan - One of the oldest ARBs. It’s cheap, widely available as a generic, and often the first choice after olmesartan. Studies show it lowers blood pressure just as well, though it may be slightly less effective in some patients with high baseline pressure.
- Valsartan - Often used in people who also have heart failure or diabetes. It’s been shown to reduce the risk of heart attacks and strokes in high-risk patients. Available as a generic, and sometimes combined with diuretics.
- Irbesartan - Similar effectiveness to olmesartan. It’s sometimes preferred for people with diabetic kidney disease because it has strong evidence for protecting kidney function.
- Candesartan - Longer-lasting effect, so it can be dosed once daily. Often used if other ARBs haven’t worked well.
All ARBs share similar side effect profiles: dizziness, elevated potassium, and rare angioedema. But if you had trouble with olmesartan, switching to another ARB might help-some people react differently to each one.
ACE Inhibitors
These are the older cousins of ARBs. They block the same hormone pathway but do it earlier in the process.
- Enalapril - A classic, low-cost ACE inhibitor. Often used as a first-line alternative. It can cause a dry cough in up to 20% of users-that’s the most common reason people stop taking it.
- Lisinopril - Very popular in the UK. Once-daily, inexpensive, and effective. Like enalapril, cough is the main drawback. Also carries a small risk of angioedema, especially in Black patients.
- Ramipril - Often prescribed for people with heart disease or after a heart attack. Has strong evidence for reducing long-term cardiovascular risk.
ACE inhibitors are not for everyone. If you’ve had a cough from one before, you’ll likely get it from others too. They’re also not recommended during pregnancy.
Calcium Channel Blockers (CCBs)
These work differently-they relax the muscles in your blood vessel walls. They’re often used when ARBs or ACE inhibitors don’t work or cause side effects.
- Amlodipine - The most common CCB in the UK. Very effective, once-daily, and cheap. Side effects include swollen ankles, flushing, and headaches. These usually improve after a few weeks.
- Diltiazem - Used less often for pure hypertension, but helpful if you also have angina or a fast heart rate.
- Nifedipine - Fast-acting, but usually reserved for short-term use or emergencies because of its strong effect.
CCBs are especially good for older adults and Black patients, who often respond better to them than to ACE inhibitors or ARBs.
Comparison Table: Benicar vs Top Alternatives
| Medication | Class | Typical Dose | Cost (UK Generic) | Common Side Effects | Best For |
|---|---|---|---|---|---|
| Olmesartan (Benicar) | ARB | 20-40 mg daily | £5-£10/month | Dizziness, diarrhea, fatigue | Patients needing strong BP control without cough |
| Losartan | ARB | 50-100 mg daily | £3-£7/month | Dizziness, muscle cramps, elevated potassium | Cost-sensitive patients, those with mild hypertension |
| Valsartan | ARB | 80-320 mg daily | £6-£12/month | Dizziness, back pain, upper respiratory infection | Patients with heart failure or diabetes |
| Lisinopril | ACE inhibitor | 10-40 mg daily | £3-£8/month | Dry cough (up to 20%), dizziness, angioedema | Patients without cough history, younger adults |
| Amlodipine | Calcium channel blocker | 5-10 mg daily | £3-£6/month | Swollen ankles, flushing, headaches | Older adults, Black patients, those with side effects from ARBs/ACE inhibitors |
Which Alternative Is Right for You?
There’s no single best drug. The right choice depends on your age, ethnicity, other health conditions, and how your body reacts.
If you’re over 55 or of African or Caribbean descent, guidelines from the UK’s NICE recommend starting with a calcium channel blocker like amlodipine-not an ARB or ACE inhibitor. That’s because these groups tend to respond better to them.
If you have diabetes and kidney disease, irbesartan or valsartan might be preferred because they protect your kidneys better than other options.
If you’re young and otherwise healthy, and you don’t want a cough, an ARB like losartan is a solid, low-cost choice.
If you’ve had stomach issues on olmesartan, switching to an ACE inhibitor or CCB could help. But if you’ve had a cough on lisinopril before, you’ll likely get it again.
Don’t switch on your own. Always talk to your GP or pharmacist. Stopping or changing blood pressure meds without guidance can be dangerous.
What About Natural Alternatives?
You might have heard about magnesium, garlic, beetroot juice, or meditation lowering blood pressure. Some of these can help-but they’re not replacements for medication.
For example, studies show that reducing salt intake, losing weight, and getting regular exercise can lower systolic blood pressure by 5-10 mmHg. That’s significant. But if your blood pressure is 160/95, lifestyle changes alone won’t get you to the target of 130/80.
Supplements like coenzyme Q10 or hibiscus tea might offer small benefits, but they’re not regulated like prescription drugs. Their strength varies, and they can interact with your meds. Always tell your doctor if you’re taking them.
When to Stick With Benicar
Just because there are alternatives doesn’t mean you need to switch. If olmesartan is working well-your blood pressure is controlled, you have no side effects, and it’s affordable-there’s no reason to change.
Many people stay on it for years. It’s safe for long-term use. The key is consistency: taking it every day, even when you feel fine.
Regular blood pressure checks and kidney function tests (like creatinine and potassium levels) are important if you’re on any ARB long-term.
Final Thoughts
Benicar (olmesartan) is a strong, effective blood pressure medication-but it’s not the only one. Alternatives like losartan, lisinopril, and amlodipine are just as effective for many people, often at lower cost and with different side effect profiles.
The best choice isn’t about which drug is "strongest." It’s about which one fits your body, your lifestyle, and your health goals. Work with your doctor to find the right match. Don’t rush the decision. Try one alternative at a time. Give it 4-6 weeks to see how you feel.
High blood pressure is a silent condition. You won’t feel it until it’s too late. But with the right medication-and the right support-you can live a long, healthy life without ever needing to feel its effects.
Is Benicar better than losartan?
Benicar (olmesartan) and losartan are both ARBs and work similarly. Olmesartan may lower blood pressure slightly more in some people, but losartan is cheaper and has been used longer with strong safety data. For most people, losartan is just as effective and often the better first choice due to cost.
Can I switch from Benicar to amlodipine?
Yes, many people switch successfully. Amlodipine is often preferred for older adults or those of African or Caribbean descent. Side effects like swollen ankles are common at first but usually improve. Never stop Benicar suddenly-your doctor will guide you through a safe transition.
Why did my doctor switch me from Benicar to lisinopril?
Lisinopril is an ACE inhibitor, not an ARB. Your doctor may have switched you because you had side effects like diarrhea from olmesartan, or because you have heart failure or diabetes-conditions where ACE inhibitors have proven extra benefits. But if you develop a dry cough, let your doctor know.
Are there any foods or supplements I should avoid with Benicar?
Avoid potassium supplements or salt substitutes high in potassium-olmesartan can raise potassium levels. Also limit grapefruit juice, as it can interfere with how your body processes some blood pressure meds. Always check with your pharmacist before starting any new supplement.
How long does it take for a new blood pressure med to work?
Most medications start working within a week, but it can take 4-6 weeks to reach full effect. Don’t judge effectiveness after just a few days. Keep taking your medication as prescribed, and track your blood pressure at home if possible. Your doctor will check your levels after 4-6 weeks to decide if a dose change is needed.
