Atenex 100 mg Tablet

Atenex 100 mg Tablet contains 100 mg of atenolol in each tablet. Atenolol is a beta blocker medicine used to help treat high blood pressure, angina (chest pain), and certain heart rhythm problems, and it may also be used after a heart attack in some patients. Atenex 100 mg Tablet is a higher-strength tablet for patients whose doctor has decided that 100 mg is appropriate for their condition and response to treatment.

How it works: Atenolol works by slowing the heart rate and reducing how hard the heart has to work, which can lower blood pressure and reduce chest pain. As an oral tablet, Atenex 100 mg Tablet is swallowed and then absorbed to provide steady beta-blocking effects through the day.

Compared with Atenex 25 mg Tablet, Atenex 100 mg Tablet provides a much larger single dose of atenolol in one tablet. This strength is usually chosen when a lower strength is not enough, or when a doctor wants a specific higher maintenance dose; it should not be used as a starting dose unless a clinician has prescribed it that way.

• High blood pressure
• Chest pain (angina)
• Certain fast or irregular heart rhythms
• Heart attack follow-up in selected patients

• Swallow Atenex 100 mg Tablet whole with a glass of water; do not crush or chew it unless your doctor says otherwise.
• Take it at the same time each day to help you remember doses and keep levels steady.
• It can be taken with or without food, but taking it the same way each day is best.
• Do not stop Atenex 100 mg Tablet suddenly, because stopping a beta blocker too fast can worsen chest pain or raise heart strain.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• Follow your prescriber’s instructions carefully, since this 100 mg tablet is a higher-strength option and may not be right for every patient.

Each Atenex 100 mg Tablet contains 100 mg of atenolol.

The maximum daily amount depends on the patient and the reason for treatment, so do not take more than prescribed.
