Diltiazem Hydrochloride
About Diltiazem Hydrochloride
Diltiazem Hydrochloride is an injectable medicine used to quickly control a fast or irregular heart rate. It is primarily used in emergency or hospital settings to treat conditions where the heart beats too rapidly, such as certain heart rhythm disorders. This medicine helps stabilise the heart's rhythm in acute situations.
Because this is an injection given under medical supervision, its frequency of use depends entirely on your immediate medical need. It is injected directly into a vein to provide rapid relief. To help support your heart health during and after treatment, your doctor may suggest lifestyle changes such as eating a low-sodium diet and reducing stress.
Common side effects include mild dizziness, flushing, or a headache. However, you must inform your healthcare provider immediately if you experience serious side effects like a very slow heartbeat, severe dizziness, or difficulty breathing.
Before receiving this medicine, tell your doctor if you have a history of heart failure, kidney disease, or liver damage. Do not take this medicine if you have severe low blood pressure, a very slow heart rate, or certain heart blockages without a working pacemaker.
This medicine can interact with alcohol, smoking, and other heart medications like beta-blockers, which may cause your heart rate to drop too low. If you are pregnant, breastfeeding, or an older adult, consult your doctor to ensure this treatment is safe for your specific situation.

Patients Concern
Disease/Condition Glossary
Atrial fibrillation: Atrial fibrillation is a type of arrhythmia that occurs due to disorganized electrical signals in the heart. It is marked by a rapid and irregular pulse rate that causes poor blood flow. This condition may not have symptoms; if they occur, the symptoms include dizziness, fainting, palpitations (a feeling as if the heart is pounding or racing), weakness, shortness of breath, chest pain or tightness.
Atrial flutter: Atrial flutter is a condition in which the atria (heart's upper chambers) beat too fast. This causes the heart to beat rapidly. However, the pulse rate/rhythm is usually regular in case of atrial flutter. Symptoms include dizziness, palpitations, and shortness of breath.
Paroxysmal Supraventricular Tachycardia (PSVT): Supraventricular tachycardia is the episodes of the rapid heart rate which begin above the ventricles (the heart's lower chambers) occurring due to disruption of the heart's electrical signals. There may be symptoms such as palpitations or no symptoms at all.
