Signs & Symptoms of Too Much Blood Pressure Medication

High or low blood pressure can be a life-threatening condition, causing heart attacks, strokes, aneurysms and blood clots. Physicians prescribe a number of different types of medications to help control a person's blood pressure. However, there can also be risks associated with these drugs if someone takes too much. Here are some signs to watch for.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Beta Blockers

Beta blockers treat high blood pressure by blocking nerve impulses to the heart and blood vessels. Some examples of beta blockers are Atenolol (tenormin) Zebeta (bisoprolol) and Coreg (carvedilol). According to the National Heart Lung and Blood institute, beta blockers make the heart beat slower and not as hard, lowering blood pressure and relaxing the heart so it's not be so overworked. But an overdose of beta blockers can cause:

  • breathing problems
  • fever
  • drowsiness
  • blurred or double vision
  • confusion
  • even a coma or death

ACE Inhibitors

Benicar & Potassium

ACE (for angiotensin converting enzyme) inhibitors like Benazepril (Lotensin) or Captopri (Capoten) prevent the hormone angiotensin II, which causes blood vessels to narrow. As a result, the vessel will relax, allowing an easier blood flow and resulting in lower blood pressure. If too much of this medication is taken it can result in renal problems and severely low blood pressure. The signs of an overdose can include dizziness, change in consciousness, inability to urinate or a general bad feeling. If you suspect someone has taken too much of an ACE inhibitor you should immediately seek medical assistance.

Alpha Blockers

Signs of overdose can include dizziness, headaches, hypotension and even fluid retention.

Vasodilators

The Most Popular High Blood Pressure Medications

Physicians frequently look to improve circulation with vasodilators like hydralazine (Apreso-line) and minoxidil (Lonetin), which help reduce blood pressure by relaxing the muscles in the wall of the vessel.

Calcium Channel Blockers

Cardizem (diltiazem), Plendil (felodipine) and Norvasc (amlodipine) and other calcium channel blockers work by providing more oxygen to the heart, helping it to pump more effectively. Although each medication is different, this class of drugs has a poisonous ingredient, calcium channel antagonist, that can cause potentially fatal health risks when too much is taken. Symptoms include slurred speech, a markedly slow heartbeat, confusion and even unconsciousness, requiring immediate treatment.
