Losartan is a prescription medication known as an angiotensin II receptor blocker (ARB) used primarily to manage high blood pressure and protect renal function in patients with diabetic nephropathy. By relaxing the vascular system, this active ingredient helps the heart pump blood more efficiently, reducing the risk of cardiovascular events like stroke or heart attack.

- Discreet tracked delivery directly from our registered UK pharmacy
More information
"Losartan is a foundational treatment for patients managing hypertension, particularly those who may have experienced a persistent dry cough with ACE inhibitors. It is frequently prescribed to lower blood pressure, reduce the long-term risk of stroke in patients with an enlarged heart, and provide essential kidney protection for those living with type 2 diabetes and nephropathy."

Losartan is a cardiovascular medication used to treat hypertension (high blood pressure) and protect the kidneys from damage caused by diabetes. It is a member of the angiotensin II receptor antagonist family, which is often chosen as a reliable alternative for patients who cannot tolerate other types of blood pressure medication.
The active ingredient in this medication is Losartan Potassium. Each tablet contains a specific amount of this compound, which works specifically on the hormonal system that regulates your blood pressure and fluid balance.
Many users report that Losartan is well-tolerated and effectively maintains stable blood pressure readings when taken consistently. While individual results vary, it is highly regarded for its lower incidence of the "dry cough" side effect often associated with similar heart medications.
Every order of Losartan includes a Patient Information Leaflet (PIL) that contains detailed technical data and safety instructions. You should read this leaflet thoroughly before starting your treatment to understand the specific guidance for your medication.
Losartan works by blocking the action of a natural substance called angiotensin II, which normally causes your blood vessels to tighten and narrow. By preventing this action, the medication allows your blood vessels to relax and widen, which lowers your overall blood pressure and reduces the workload on your heart.
You should take your tablet once a day at approximately the same time, either with or without food. Consistency is key for managing hypertension, so it is helpful to incorporate it into a daily routine, such as during breakfast or before bed.
The appropriate dosage is determined by a healthcare professional based on your specific health needs and blood pressure readings. Most adults start on a standard daily dose, which may be adjusted over time to ensure your blood pressure remains within a healthy target range.
Like all medicines, Losartan can cause side effects, although not everybody gets them. Common side effects may include:
- Dizziness or lightheadedness
- Fatigue or tiredness
- Low blood pressure (hypotension)
- High potassium levels in the blood
You should consult your doctor before using Losartan if you have kidney or liver problems, or if you are pregnant or breastfeeding. It is important to avoid using salt substitutes that contain potassium while taking this medication, as this can lead to dangerously high potassium levels in your body.
Losartan is often compared to ACE inhibitors and other ARBs used for blood pressure management.
| Medication Class | Example | Key Characteristic |
|---|---|---|
| ARBs (Angiotensin Receptor Blockers) | Losartan, Candesartan | Blocks angiotensin receptors; lower risk of dry cough. |
| ACE Inhibitors | Ramipril, Lisinopril | Prevents production of angiotensin; may cause a dry cough. |
| Calcium Channel Blockers | Amlodipine | Relaxes muscles in vessel walls; often used as a first-line treatment. |
Can I take Losartan if I have diabetes?
Yes, Losartan is frequently prescribed to patients with type 2 diabetes because it helps protect the kidneys from the damage often caused by high blood pressure.
How long does it take for Losartan to work?
While some effect is seen within a week, it can take between three to six weeks of regular use to reach the full blood-pressure-lowering potential of the medication.
Should I avoid certain foods while taking Losartan?
You should avoid grapefruit juice and salt substitutes that are high in potassium, as these can interfere with how the medication works or affect your mineral balance.
