ATENOLOL Tablets 50mg "SAWAI" [Generic TENORMIN]

Product Overview

Atenolol Tablets 50mg "Sawai" are the generic form of Tenormin (atenolol) manufactured in Japan by Sawai Pharmaceutical. Atenolol is a cardioselective (beta-1 selective) beta-blocker indicated for controlling high blood pressure, relieving chest pain (angina), and treating certain rapid heart rhythms. It works by blocking the beta-1 receptors in the heart, which slows down the heart rate and reduces the force of contraction. This action lowers blood pressure and decreases the heart's oxygen demand, helping prevent angina attacks. Because atenolol selectively targets beta-1 receptors, it has little effect on beta-2 receptors in the lungs, so it is less likely to provoke breathing issues than non-selective beta blockers. The 50mg strength is the standard adult dose, conveniently delivered in a single tablet for once-daily use. 

Dosage Guidelines

The usual prescribed dose for atenolol in adults is 50 mg taken once per day, which is exactly one Atenolol 50mg "Sawai" tablet daily. Take the tablet at the same time each day with a glass of water. Depending on individual needs, a doctor may adjust the dosage. If a lower dose is required (for instance, for initial therapy or in very sensitive patients), the doctor might prescribe 25 mg per day using the lower strength tablets. On the other hand, if the effect is insufficient, the dose can be increased up to a maximum of 100 mg per day (usually as two 50mg tablets taken together once daily). Dosage adjustments should only be done under medical advice. Do not change the dose or stop taking atenolol on your own. If it becomes necessary to discontinue atenolol, your physician will advise a gradual reduction of the dose rather than an abrupt stop. Stopping suddenly can cause your blood pressure to spike or chest pain to worsen due to a rebound effect.

Possible Side Effects

When taking the 50mg atenolol tablet, you may experience side effects similar to those of other beta-blockers. Common side effects tend to be mild, and can include:

• Low blood pressure and dizziness: You might feel lightheaded, especially upon standing, as atenolol can lower blood pressure. This orthostatic dizziness is usually mild. To reduce this effect, rise slowly from sitting or lying positions.

• Bradycardia (slow heart rate): Atenolol’s intended effect is to slow the heartbeat, but in some people it may slow it a bit more than needed, leading to fatigue or lightheadedness. If you notice an excessively slow pulse or any fainting episodes, notify your doctor.

• Fatigue or weakness: Some patients report feeling more tired or having less energy, especially when first starting the medication. This is due to the decrease in heart rate and blood pressure.

• Cold extremities: Beta-blockers can reduce circulation to the hands and feet, so you may notice cold fingers or toes. This is generally not dangerous, but mention it to your doctor if it bothers you.

• Digestive issues: A small number of people experience nausea, stomach discomfort, or diarrhea. Taking your dose with food might help if you have an upset stomach.

Serious adverse reactions are rare at recommended doses. However, if you experience symptoms such as severe shortness of breath or wheezing (possible in individuals with asthma or lung issues), very slow heart rate, irregular heartbeat, severe dizziness or fainting, or swelling of ankles (a sign of potential heart failure), seek medical attention immediately. These could indicate an excessive effect of the medication or an uncommon reaction that needs prompt evaluation. Overall, atenolol is well-tolerated by most patients, and side effects (if they occur) are often manageable or resolve as your body adapts to therapy.

FAQ

Q: What if I miss a dose?
A: If you miss your scheduled dose of atenolol, take it as soon as you remember on the same day. But if it’s almost time for your next dose, skip the missed dose and resume your normal dosing schedule with the next tablet. Do not take a double dose to make up for the missed one. Missing an occasional dose may slightly increase your heart rate or blood pressure, so try not to miss doses regularly.

Q: How should I store Atenolol 50mg tablets?
A: Store the tablets in a cool, dry place at room temperature (approximately 15–25°C). Keep them in their original blister pack or container until it’s time to take them, to protect from moisture. Always keep all medications out of reach of children and pets.

Q: Is long-term use of atenolol 50mg safe?
A: Yes, atenolol is intended for long-term use in managing chronic conditions like high blood pressure and angina, and using the 50mg dosage over the long term is generally safe under medical supervision. Many patients take atenolol for years successfully.
