How this medicine works
The U.S. public label describes TENORMIN as a preferential beta-1 selective beta blocker and explicitly notes that this selectivity is not absolute. This mechanism helps read drug class and label cautions; it does not determine an individual's heart rate, blood pressure, breathing status, kidney function, suitability, tablet count or any combination plan.

A medicine may use different brand names across markets. Keep the market, brand, generic name, dosage form and route together; one matching field does not prove that two packs are the same or interchangeable.

What this page can show
This is a source-traceable public record. It helps you read the product identity and its listed source documents; each market still needs its own current record check.
What to bring to the next conversation
Bring the actual pack, the label or prescription, and a complete medicine list when you speak with a pharmacist or clinician.

PRODUCT PRESENTATION IDENTITY
Strength, pack and device identity
Package strength is not an individual dose. These fields help identify the exact labelled product; they do not calculate how much, how often, a missed-use action, splitting, switching or conversion.
How to read a score line: ‘scored’ or ‘unscored’ first identifies this labelled presentation. A score line by itself does not permit self-splitting, reducing or changing the product. Only an explicit statement in the current label for this exact presentation, checked with a pharmacist against the prescription, can support any further handling.

First match the market, dosage form and labelled amount on the pack in hand. The number of tablets, sachets or devices in a pack is not a personal dose or schedule.

PUBLIC LABEL IMAGE
Appearance and package-text clues
This current public-label package panel helps check the brand, generic name, strength and dosage-form clues only. It does not authenticate a product in hand or establish originator status, availability, sale eligibility, another package or another market.
Open the public label source ↗LABEL READING · NOT A PRESCRIPTION
TENORMIN label reading: 25, 50 and 100 mg identify tablets; they do not answer “how many tablets”
Reading level: drug-specific label reading. This record has been expanded around its dosage form or a higher-risk reading question; the current target-market label and professional review still apply.
This module reads only TENORMIN, atenolol, oral tablets, labelled amount per tablet, NDCs, packaging and key warnings in the U.S. DailyMed public label. It provides no individual tablet count, timing, splitting, co-use, stopping, switching or purchase plan.
- Check TENORMIN, atenolol, oral-tablet form, the stated 25/50/100 mg per tablet, actual NDC, 90-tablet bottle and target market together. Mg is the labelled amount in an exact tablet, not a web rule for an individual's daily tablet count or for self-exchanging another strength, brand, form or beta blocker.
- The label's appearance description shows a bisect score on the 50 mg tablet; that only helps identify this exact tablet. Whether it may be split, how to address swallowing difficulty, or whether another strength is needed must be confirmed from the actual prescription, current label and a pharmacist or prescriber—not from a score, a prior pack or this webpage.
- The label contains cautions involving sudden discontinuation, heart rate/blood pressure, kidney function, respiratory disease, pregnancy/breastfeeding and the presence of other medicines on the list. These need professional review in the actual context. Do not self-start, adjust, stop, combine, alternate or replace it because of a feeling or another same-class pack.
- With fainting, breathing difficulty, marked palpitations/abnormal heart rate, chest pain, a severe allergic reaction or another acute serious concern, prioritise local emergency medical care. Do not wait for a web search or self-counteract or test with another pack.

Match five details before using a safety record
- Brand and generic nameBoth must match the medicine named by the record.
- Dosage form and strengthTablet, capsule, injection, inhaler, patch and eye drop are not interchangeable.
- Market and notice dateA record applies only to the country or region and date it names.
- Lot, pack and manufacturerRecord these only when the official notice specifically names them.
- Current product informationA historical record may have been superseded by the current label.
This checklist only helps organise the right question. It does not create a personal conclusion about stopping, switching, dose, combination or suitability.

For severe or rapidly worsening symptoms, suspected overdose, a severe allergic reaction, loss of consciousness or another emergency, use local emergency services. Do not wait for an online alert search or change a medicine from this page.
PRIVATE FAMILY LIST
Bring this record into a local medicine list

Six checks for this medicine pack
Use this card to organise questions about TENORMIN (atenolol). Keep the exact pack, its current label and the full medicine list together.
Identify the exact product
TENORMIN is the brand in this record and atenolol is the active-ingredient name. Check both with the dosage form (Dosage form and presentation as documented in the linked primary label) and the market on the actual pack.
Read the labelled strength in context
mg, mcg, mg/mL or a percentage describes the labelled amount in one tablet, capsule, measured volume, spray or other unit. It is not an answer to how many units a person should take.
Check before splitting or opening
Before splitting, crushing, chewing or opening anything, find an explicit instruction for this exact product in its current label and ask a pharmacist. A score line or a previous pack is not enough by itself.
Put every product on one list
Include prescriptions, over-the-counter products, eye drops, creams, vitamins, minerals, herbs and supplements. A pharmacist or prescriber needs the whole list before any combination, alternation, switch or stop is considered.
Ask a specific pharmacogenetics question
Ask which medicine, which gene and what clinical decision a result could change. A gene–drug association does not mean broad genetic testing is needed for everyone and must not be used to change treatment without professional review.
Know when to seek urgent help
For a suspected overdose, a severe allergic reaction, fainting or difficulty breathing, use the local emergency or poison-information service now. Do not wait for a website reply or alter several medicines to test what caused it.
This card does not calculate a dose, decide whether medicines can be combined, or replace a clinician or pharmacist. Market-specific current labels and the person's full context still need review.
HOW IT WORKS · NOT A TREATMENT PLAN
How atenolol works: the beta-1 receptor-blocking pathway described in the label
- “Beta-1 selective” and “beta blocker” are mechanism and class clues; they do not permit self-combining, alternating, substituting or milligram-converting with another beta blocker. The exact product, strength, dosage form, target-market label, prior reactions and complete medicine list all need review together.
- A mechanism or a labelled indication cannot let a webpage decide whether a person is suitable for this medicine or should change use. For heart rate, blood pressure, breathing symptoms, kidney function or an added medicine, obtain review from a professional who can see the complete history, tests and medicine list.
- Mechanism information does not replace pharmacovigilance, interaction review or emergency assessment. For an acute serious problem, prioritise local emergency care; for other questions, contact a pharmacist or prescribing team with the actual pack and complete medicine list.

MARKET SCOPE
Market-record boundary
United States
Public label and three exact 90-tablet bottle panels linkedThe page separately displays the specified NDC and 90-tablet bottle for TENORMIN atenolol 25 mg, 50 mg and 100 mg. The 50 mg score is only an appearance clue; it does not establish splitting, individual tablet count, actual marketing, stock, purchase, authenticity or interchangeability.
Mainland China, EU, Japan and other markets
Market record not establishedNo local trade name, approval, packaging, supply, sale eligibility, originator/generic relationship or interchangeability is inferred from the U.S. label, NDA, NDC, English brand, package image or label entity; every market requires separate checking against current local regulatory material.
How to read this record
Read each document in its stated market, date and dosage-form context. A historical record is not a current label and does not support individual medical, substitution or purchasing conclusions.
Keep international and mainland China records separate
This page has a U.S. public history/regulatory archive but no mainland China record for this specific product. That does not establish whether the medicine exists, is approved or is available in mainland China. Verify product identity, dosage form, strength, holder and the current label item by item.
RECORD FAQ
Record questions
The 50 mg tablet has a score. Does that mean I can split it myself or combine strengths to make another milligram number?
No decision follows from that. The score and the 25, 50 and 100 mg values are identity or appearance information for exact tablets in this U.S. label; they do not establish an individual's tablet count, splitting, make-up use, conversion, same-day combination, alternate-day use or replacement with another beta blocker. Have a pharmacist or prescribing team check the actual pack, prescription and complete medicine list.
