Hydrochlorothiazide, while generally safe and effective, can cause side effects. Common ones include dizziness, lightheadedness, and dehydration due to increased urination. These are usually mild and often subside as your body adjusts. However, some individuals experience more serious reactions.
Serious Side Effects
Less common, but requiring immediate medical attention, are allergic reactions, characterized by rash, hives, swelling, or difficulty breathing. Furthermore, hydrochlorothiazide can elevate blood sugar levels, potentially worsening diabetes. It may also increase cholesterol and triglyceride levels. Low potassium levels (hypokalemia) are a possibility and can lead to muscle weakness or irregular heartbeat. This risk increases with concurrent use of certain other medications. Sun sensitivity is another potential side effect; increased sun exposure should be avoided.
Medication Interactions
Before starting hydrochlorothiazide, inform your doctor of all other medications you are taking, including over-the-counter drugs and supplements. Certain medications, such as lithium and digoxin, interact negatively with hydrochlorothiazide and require careful monitoring. Your doctor will adjust dosages or suggest alternatives if necessary. Regular blood tests might be required to check potassium, glucose, and cholesterol levels.
Discontinue Medication?
Stop taking hydrochlorothiazide and contact your doctor immediately if you experience any unusual symptoms. Never abruptly discontinue the medication without your doctor’s guidance; gradual tapering is recommended to prevent potential rebound effects.
