Ziblok 50 Tablet

Ziblok 50 Tablet is a prescription medicine that contains 50 mg of atenolol in each tablet. Atenolol belongs to a group of medicines called beta blockers, which help lower heart rate and reduce blood pressure. Ziblok 50 Tablet is used to treat high blood pressure, chest pain (angina), and certain heart rhythm problems, and it may also be prescribed after a heart attack when a doctor feels it is appropriate. This 50 mg tablet is a stronger option than Ziblok 25 Tablet and should be used only when your doctor has assessed that this dose is right for you.

How it works: Atenolol in Ziblok 50 Tablet blocks beta-1 receptors in the heart, which helps the heart beat more slowly and with less force. As a tablet, it is swallowed and absorbed into the body to provide steady blood pressure and heart-rate control over time.

Ziblok 50 Tablet provides 50 mg of atenolol per tablet, which is a higher-strength option than Ziblok 25 Tablet. Doctors may choose Ziblok 50 Tablet when a lower dose is not enough to control blood pressure, heart rate, or angina symptoms, or when a patient is being stepped up to a stronger dose. Because it is a higher-strength tablet, it may be more likely to lower pulse and blood pressure noticeably, so it is not meant for self-adjusting or casual use.

• High blood pressure
• Angina (chest pain)
• Fast or irregular heart rhythm
• Support after a heart attack when prescribed
• Heart-rate control in selected patients

• Swallow Ziblok 50 Tablet whole with a glass of water; do not crush or chew it unless your doctor or pharmacist tells you otherwise.
• Take it at the same time each day to help you remember doses and keep levels steady.
• It may be taken with or without food; if it upsets your stomach, taking it with food may help.
• Do not stop Ziblok 50 Tablet suddenly, because stopping a beta blocker too fast can worsen chest pain or heart problems.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• If your doctor asks you to monitor your pulse or blood pressure, check them regularly while using this tablet.

Each Ziblok 50 Tablet contains 50 mg of atenolol. The tablet may be taken once daily for many conditions, though some patients may need a different schedule based on their response and kidney function; your doctor decides the exact dose and timing. Do not take more than prescribed, and do not change the number of tablets per day on your own.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Atenolol may include:

• Tiredness or low energy, which can be more noticeable with this 50 mg strength
• Dizziness or lightheadedness
• Slow pulse
• Cold hands or feet
• Nausea or stomach upset
• Sleep changes or vivid dreams

• Use extra caution if you have asthma, COPD, or a history of wheezing because beta blockers can tighten the airways in some people.
• Tell your doctor if you have diabetes, since atenolol can mask signs of low blood sugar such as a fast heartbeat.
• Do not stop Ziblok 50 Tablet suddenly; the dose may need to be reduced gradually under medical supervision.
• This 50 mg strength may lower blood pressure and heart rate more strongly than Ziblok 25 Tablet, so dizziness or weakness can be more likely at first.
• Avoid alcohol excess, which can add to dizziness and low blood pressure.
• Be careful when driving or using machinery until you know how this tablet affects you.
• Tell your doctor if you have severe circulation problems, heart failure, or a very slow pulse before starting treatment.

• Other blood pressure medicines, especially calcium channel blockers such as verapamil or diltiazem
• Insulin and diabetes medicines, because atenolol can mask low blood sugar symptoms
• Digoxin, which can also slow the heart rate
• Clonidine, because stopping it incorrectly can cause blood pressure to rise
• Certain asthma medicines, since atenolol may reduce their effect
