Losartan, while generally well-tolerated, can cause side effects. Common ones include dizziness, headache, and fatigue. These usually lessen with continued use. However, some individuals experience more serious reactions.
Serious Side Effects Requiring Immediate Medical Attention
Seek immediate medical help if you experience angioedema, characterized by swelling of the face, lips, tongue, or throat. This is a rare but potentially life-threatening side effect. Similarly, report any signs of liver problems, such as jaundice (yellowing of the skin or eyes), dark urine, or persistent abdominal pain. Kidney problems, manifesting as decreased urination or swelling in the legs and feet, also require prompt medical attention. A persistent, dry cough is another potential adverse reaction you should discuss with your doctor.
Less Common, But Noteworthy Side Effects
Less frequently reported side effects include diarrhea, nausea, and muscle cramps. These are usually mild and temporary. Changes in blood counts, including low red blood cell count (anemia) or low white blood cell count (leukopenia), are less common but significant. Your doctor will monitor for these through regular blood tests. Always inform your doctor about any new or worsening symptoms.
