Losartan is a common medication prescribed to manage high blood pressure and protect kidney function in individuals with diabetes. Like all medications, it’s important to be aware of both the benefits and potential side effects, especially when taking it over an extended period. While many side effects are temporary and improve as your body adjusts, understanding the long-term effects is crucial for informed healthcare decisions.
One of the primary long-term concerns associated with losartan is its potential impact on kidney function. While losartan is often prescribed to protect kidneys, especially in diabetic patients, prolonged use can sometimes lead to reduced kidney function in some individuals. This doesn’t mean losartan is harmful to the kidneys in the long run for everyone, but it necessitates regular monitoring by your doctor.
Your healthcare provider will typically conduct routine blood tests to assess your kidney function while you are taking losartan long-term. These tests help to detect any changes early on and allow for timely adjustments to your treatment plan if needed. It’s essential to attend all scheduled appointments and blood tests to ensure your kidneys are functioning optimally while on this medication.
While kidney-related issues are the most emphasized long-term side effect, it’s also worth considering how some common short-term side effects might persist or evolve over time.
Initially, you might experience common side effects such as:
- Dizziness: Feeling lightheaded, especially when standing up quickly. This is often manageable by getting up slowly and staying hydrated.
- Headaches: These usually subside within the first week. Persistent or severe headaches should be reported to your doctor.
- Nausea and Vomiting: Taking losartan with food can help alleviate these symptoms. Sticking to bland foods and staying hydrated is also advisable.
- Diarrhea: Maintaining adequate fluid intake is crucial to prevent dehydration. If diarrhea is severe or persistent, consult your doctor.
- Muscle or Joint Pain: While often temporary, any unusual or persistent muscle pain, weakness, or fatigue should be discussed with your doctor.

These common side effects are generally not long-term concerns if they resolve within a few days or weeks as your body adapts to the medication. However, if any of these persist or worsen over time, it’s important to discuss them with your healthcare provider. They can assess whether these symptoms are related to losartan or another underlying issue, and advise on the best course of action.
In rare cases, losartan can cause serious side effects, which, although not typically considered “long-term” in the sense of developing gradually over many years, can have lasting implications if not addressed promptly. These include:
- Liver Problems: Yellowing of the skin or eyes (jaundice) can indicate liver issues and requires immediate medical attention.
- Pancreatitis: Severe stomach pain can be a sign of an inflamed pancreas and also needs urgent medical evaluation.
- Blood or Bone Marrow Disorders: Symptoms like unusual paleness, fatigue, easy bruising, bleeding, sore throat, or fever could indicate blood disorders.
- Potassium Level Changes: Weakness, irregular heartbeat, muscle cramps, or pins and needles can be signs of potassium imbalance.
- Severe Allergic Reactions (Anaphylaxis): Though rare, anaphylaxis is a life-threatening allergic reaction requiring immediate emergency medical help. Symptoms include swelling of the face, lips, tongue, or throat, breathing difficulties, and dizziness.

While these serious side effects are rare, it’s vital to be aware of them and seek immediate medical attention if you experience any of these symptoms while taking losartan. Prompt action can prevent potential long-term complications arising from these acute issues.
In conclusion, the primary long-term side effect directly associated with losartan is the potential impact on kidney function, necessitating regular monitoring. Most common side effects are temporary, but persistent symptoms should be discussed with your doctor. Serious side effects are rare but require immediate medical attention to avoid potential lasting health issues. It’s crucial to maintain open communication with your healthcare provider, attend regular check-ups, and report any concerns you have while taking losartan to ensure your health is managed effectively in the long term. For a comprehensive list of all possible side effects, always refer to the patient information leaflet provided with your medication. You can also report any suspected side effects through reporting schemes like the Yellow Card website in the UK to contribute to medication safety monitoring.
