Lonol 100 mg Tablet

Lonol 100 mg Tablet is a prescription medicine that contains 100 mg of atenolol in each tablet. Atenolol belongs to the beta blocker class of medicines, and Lonol 100 mg Tablet is used to help treat high blood pressure, chest pain (angina), and certain heart rhythm problems. It may also be used after a heart attack to lower the heart’s workload and reduce strain on the cardiovascular system.

How it works: Atenolol blocks beta receptors in the heart, which helps slow the heart rate and reduce the force of each heartbeat. In tablet form, Lonol 100 mg Tablet provides a measured oral dose that works over time to lower blood pressure and lessen the heart’s oxygen demand.

Lonol 100 mg Tablet is a higher-strength tablet, so it is usually chosen when a doctor has already assessed the patient’s response to atenolol and needs a stronger dose for control of blood pressure or heart rate. Because it contains 100 mg in one tablet, it may be more suitable for people who need a full maintenance dose rather than a low starting dose; it should not be assumed to be the right first dose for everyone.

• High blood pressure
• Angina (chest pain)
• Certain fast or irregular heart rhythms
• Protection after a heart attack
• Doctor-directed heart rate control

• Swallow Lonol 100 mg Tablet whole with water; do not crush or chew unless your doctor specifically says it is okay.
• 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 Lonol 100 mg Tablet suddenly, because stopping beta blockers abruptly can worsen chest pain or cause heart problems.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.
• This tablet is not meant for quick relief of chest pain during an active attack.

Each Lonol 100 mg Tablet contains 100 mg of atenolol, which is a strong tablet strength and may be higher than the starting dose many patients receive. Depending on the condition being treated, a doctor may prescribe it once daily or sometimes in divided dosing, and the exact schedule depends on the patient’s response, heart rate, blood pressure, and other medicines. The maximum daily dose is individualized by the prescriber; do not take more than directed.

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 may be more noticeable with the 100 mg strength
• Dizziness or lightheadedness
• Slow heart rate
• Cold hands or feet
• Nausea or upset stomach
• Sleep changes or vivid dreams

• Use extra caution with Lonol 100 mg Tablet if you have asthma, COPD, or other breathing problems, because atenolol can worsen bronchospasm.
• This higher-strength tablet can lower your heart rate and blood pressure more strongly, so watch for dizziness, weakness, or fainting, especially when standing.
• Tell your doctor if you have diabetes, because atenolol can mask some warning signs of low blood sugar, such as a fast heartbeat.
• Avoid stopping the medicine suddenly unless your prescriber tells you to taper it.
• Use caution with alcohol, since it can add to dizziness and low blood pressure.
• Tell your doctor about heart failure, circulation problems, kidney disease, or thyroid disorders before taking this tablet.
• Be careful driving or operating machinery until you know how Lonol 100 mg Tablet affects you.

• Other blood pressure medicines, especially calcium channel blockers or ACE inhibitors, can increase the blood pressure-lowering effect.
• Digoxin or other medicines that slow the heart can increase the risk of a very slow pulse.
• Insulin or diabetes medicines may need closer monitoring because atenolol can hide low blood sugar symptoms.
• Clonidine can interact dangerously if one medicine is stopped too quickly.
• NSAIDs such as ibuprofen may reduce the blood pressure effect in some patients.
