ATENOLOL Tablets 25mg "SAWAI" [Generic TENORMIN]

Product Overview

Atenolol Tablets 25mg "Sawai" are a Japanese-manufactured generic equivalent of Tenormin (atenolol). Atenolol is a beta-1 selective beta-blocker (cardioselective) used to treat high blood pressure (hypertension), chest pain (angina), and certain fast heart rhythms (tachyarrhythmias). By blocking beta-1 receptors in the heart, it slows heart rate and reduces the heart's workload, helping to lower blood pressure and prevent angina attacks. Because it primarily targets the heart, atenolol has minimal effect on the lungs compared to non-selective beta-blockers, making it a preferred option for patients who need a cardioselective medication.

Dosage Guidelines

For most adult patients, the typical recommended dosage of atenolol is 50 mg once daily. With the 25mg tablets, this is usually achieved by taking two 25mg tablets once per day (total 50mg). The 25mg strength provides flexibility for dose adjustment: doctors may start some patients (such as the elderly or those sensitive to blood pressure drops) at 25 mg per day (one tablet) and adjust gradually as needed. Dosage may be increased or decreased based on your condition and response, under medical supervision. The maximum recommended dose is 100 mg per day (which would be four 25mg tablets). Atenolol is typically taken by mouth once daily, around the same time each day. It can be taken with water, with or without food (food does not significantly affect absorption). Do not stop taking atenolol suddenly without consulting your doctor. Stopping this medication abruptly may cause your blood pressure or angina to worsen due to a rebound effect. If your doctor decides to discontinue therapy, they will typically taper the dose gradually.

Possible Side Effects

Like all medications, atenolol can cause side effects in some people. Common side effects are generally mild and may include:

• Dizziness or lightheadedness: You might feel dizzy, especially when standing up, due to lowered blood pressure. It's best to stand up slowly to minimize this.

• Fatigue or tiredness: A decrease in heart rate and blood pressure can make some patients feel more tired or lethargic, especially when first starting the medication.

• Slow heartbeat (bradycardia): Atenolol's heart-rate-lowering effect may cause a slower pulse. In most cases this is mild, but if you feel your heart rate is very slow or you experience fainting, inform your doctor.

• Cold hands and feet: Reduced circulation to extremities might lead to cold or numb hands and feet.

• Nausea or stomach discomfort: Some people may experience upset stomach, nausea, or diarrhea. Taking the tablet with food can help if you have a sensitive stomach.

• Mood or sleep changes (less common): A few individuals report mood changes, trouble sleeping, or vivid dreams while on beta-blockers.

Rare but serious side effects may include severe shortness of breath or wheezing (possible in patients with asthma), very slow heart rate, severe dizziness/fainting, or signs of heart failure (such as swelling in ankles, extreme fatigue). These are uncommon, but if you experience any serious symptoms, seek medical attention promptly. Most patients taking atenolol at prescribed doses tolerate it well, and any mild side effects often improve as your body adjusts.

FAQ

Q: What if I miss a dose?
A: If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and take your next dose at the regular time. Do not double the dose to catch up. Continuing on your normal schedule is the safest approach.

Q: How should I store this medication?
A: Store atenolol 25mg tablets at room temperature (around 15–25°C), away from excessive heat, moisture, and direct sunlight. Keep the tablets in their original packaging until use to protect them from humidity. Always keep medications out of reach of children and pets.

Q: Is it safe to take atenolol long-term?
A: Yes, atenolol is often prescribed for long-term use to manage chronic conditions like hypertension and angina. It is generally safe to take over extended periods under a doctor’s supervision. In fact, maintaining control of blood pressure or heart rate often requires long-term therapy. 

Q: Can I take it on an empty stomach?
A: Yes. Atenolol can be taken with or without food according to your preference. Taking it on an empty stomach is generally fine, as food does not significantly alter its effectiveness. If you notice that it upsets your stomach when taken without food, you can take it with a meal.
