Hydrochlorothiazide (HCTZ) is a medication commonly used to treat hypertension as well as fluid retention. Like most medications, it has the risk of side effects. Anyone who is taking HCTZ should be aware of potential side effects and report anything new, severe or unexpected to a health care provider immediately.
According to eMedTV, thousands of patients have been involved in studies of this drug around the globe. A number of side effects have been reported. These include weakness and a sensation of spinning. Some people feel dizzy while on the drug. Low blood pressure can also occur. They may feel that their heartbeat is rapid or irregular. Numbness, a feeling of tingles, pain or weakness in the muscles can also occur. They may get a rash on their skin, a fever, darkened urine or stool that is of a clay color. Some patients will experience jaundice, a yellowing of the skin and eyes. You should contact your doctor immediately with these symptoms. He or she may need to adjust your medication or put you on another medication if you are not tolerating HCTZ well.
HCTZ can cause stomach and digestive problems that manifest themselves in a variety of ways. You may feel nauseous or vomit. Talk to your doctor about these symptoms as well. Some also have a stomach ache or problems with constipation. They may get blurred vision.
HCTZ can also affect the amount of sugar in your blood. It can increase it to cause hyperglycemia. You may find that your electrolytes become unbalanced. Low blood sodium, potassium and chloride can occur.
Some people find that they are more sensitive to the sun when taking HCTZ. You may want to avoid the sun if this affects you. Addition side effects can include pancreatitis, loss of hair and erectile dysfunction.
One of the most serious side effects is an allergic reaction. You should seek immediate emergency help if you experience the symptoms of an allergic reaction. These include trouble breathing, a swollen face, lips, tongue or throat and hives. Such a reaction can occur immediately or it may not occur right away. It can become far more serious in a matter of time.
As with any medication there are some side effects that cannot be predicted. Your chances of getting side effects range by the symptom. If you are unsure about anything, do not hesitate to contact your health care provider immediately.
