Atenolol is a medication that belongs to a group of drugs called beta-blockers. It works by blocking the action of certain natural chemicals in your body, such as adrenaline, on the heart and blood vessels. This helps to lower your heart rate, blood pressure, and strain on your heart. Atenolol is commonly used to treat conditions like high blood pressure, chest pain (angina), and to improve survival after a heart attack. It is suitable for adults who need to manage these cardiovascular conditions effectively.

Description
Dosage and usage
For high blood pressure, the usual starting dose is 25-50 mg once a day, which can be increased to 100 mg per day if needed. For angina or heart attack prevention, the usual dose is 50-100 mg once a day. Your doctor will determine the right dose for you based on your condition. It's important to take Atenolol regularly as directed. Do not suddenly stop taking it without consulting your doctor, as this can lead to serious complications. If you miss a dose, take it as soon as you remember unless it's almost time for your next dose. In case of any concerns or if you experience unusual symptoms, contact your healthcare provider promptly.
What Atenolol contains
Each Atenolol tablet contains 25 mg, 50 mg, or 100 mg of the active ingredient atenolol. The tablets also contain other ingredients such as microcrystalline cellulose, maize starch, magnesium stearate, and sodium starch glycolate.
Side effects
Common side effects of Atenolol may include tiredness, dizziness, cold hands, and slow heartbeat. Serious side effects that require immediate medical attention include difficulty breathing, swelling of the face, lips, throat, or tongue, and a sudden increase in weight. If you experience chest pain, fainting, or signs of a severe allergic reaction, seek medical help right away.
Precautions
Do not take Atenolol if you have a slow heart rate, severe circulation problems, or certain heart conditions. It is important to inform your doctor about any existing medical conditions or medications you are taking before starting Atenolol. If you have diabetes, Atenolol may mask the symptoms of low blood sugar, so closely monitor your blood sugar levels while taking this medication. Pregnant or breastfeeding women should consult their doctor before using Atenolol. If you have any concerns or questions about using this medication, talk to your healthcare provider for personalized advice.

An excellent experience.
This was an excellent experience which actually surpassed my expectations.I required a medication fairly urgently and probably just a one off however I will have no hesitation in using the service again if need be.The service was exceptionally good, courteous and helpful. My meds arrived very rapidly and I was able to fully track the delivery progress which was via a well established courier company.Highly recommend.
Quick and straightforward assessment
Quick and straightforward assessment, easy to order, fast delivery service, ability to ask questions via email, regarding the medication you’ve ordered. The only thing I was slightly disappointed with, was when I made my second order on the medication I previously purchased, as the price went up by almost £10.
