As a healthcare professional with expertise in pharmacology, I can provide you with information on the side effects of losartan potassium, which is an angiotensin II receptor blocker (ARB) used to treat high blood pressure and heart failure, and to prevent kidney problems in people with type 2 diabetes. Side effects of losartan potassium can be categorized as follows: 1. Common Side Effects: These may include dizziness, lightheadedness, headache, back pain, and fatigue. These are usually mild and tend to go away as the body adjusts to the medication. 2. Less Common Side Effects: These can include muscle pain, joint pain, stomach pain, diarrhea, and upper respiratory tract infections. 3. Rare but Serious Side Effects: More severe reactions are less common but can occur. These may include signs of an allergic reaction (rash, hives, itching, difficulty breathing, or swelling of the face, lips, tongue, or throat), severe dizziness, or fainting. 4. **Potential Side Effects Related to Kidney Function**: Since losartan is used to protect the kidneys, it is important to note that in rare cases, it can cause a condition that results in the decrease of kidney function or kidney failure. 5. Interactions with Other Medications: Losartan can interact with other medications, which can lead to increased side effects or reduced effectiveness of either drug. It is important to note that not everyone will experience side effects, and many people tolerate losartan well. If you are taking losartan potassium and are concerned about side effects, it is crucial to discuss them with your healthcare provider. read more >>
