Most candesartan side effects are relatively mild in nature and do not pose any significant health risks, although any new or bothersome symptoms that develop after beginning treatment with this medication should be reported to a doctor for further evaluation. Some of the most frequently reported side effects of this high blood pressure medication include dizziness, elevated potassium levels, and fatigue. More serious candesartan side effects that should be reported to a doctor right away include decreased urination, abdominal pain, and difficulty breathing. Any questions or concerns about possible candesartan side effects in an individual situation should be discussed with a doctor or pharmacist.
Dizziness and fatigue are among the most common candesartan side effects. While these symptoms are usually mild, they may become severe enough to make it difficult to function normally. Caution should be used when driving an automobile or performing other tasks that require focus or coordination. If these side effects are persistent or bothersome, a doctor should be notified so that the dosage can be reevaluated.
Blood tests may reveal elevated potassium levels when taking this medication. This potassium increase can lead to heart damage and may indicate problems with kidney function. Prescription drugs may be used to lower these levels, although severe cases may require the use of kidney dialysis or intensive treatment in a hospital setting. Periodic blood tests may be ordered during the duration of treatment with this medication in order to closely monitor potassium levels.
Dark-colored urine or a decrease in the amount of urine produced are potential candesartan side effects that may indicate kidney damage or impaired renal function. Sudden or severe abdominal pain, especially if accompanied by fever or vomiting, should be reported to a doctor in order to rule out complications involving the digestive system. Jaundice is a medical condition that often suggests a decline in liver function and is characterized by a yellow tint to the skin or the white portion of the eyes.
Allergic reactions can vary from mild to severe in nature and are possible candesartan side effects. Mild reactions may cause itching, hives, or a widespread rash. Potentially life-threatening complications may arise as a result of a severe type of allergic reaction known as anaphylaxis. Anaphylactic symptoms may include swelling of the tongue and throat, difficulty breathing, and loss of consciousness. Emergency medical assistance is essential when an allergic reaction is suspected, as permanent brain damage or death may occur within a matter of minutes due to an interruption to the oxygen supply.
