Do not drive or operate machines if you feel tired or dizzy while taking atenolol.
Atenolol Tablets contain the colour E110 which may cause allergic-type reactions including asthma. Allergy is more common in those people who are allergic to aspirin.
Taking your medicine
Always follow your doctor’s instructions as to how and when to take your medicine, your pharmacist may be able to advise if you are not sure. Exactly how many tablets, and how often you must take them, will be written on the label. Please read it carefully.
The doses are given below. However, doctors sometimes prescribe different doses to these: if this applies to you, discuss it with your doctor, if you have not already done so.
The tablets should be swallowed whole with water.
Adults:
High blood pressure (hypertension): 1 x 50mg or 1 x 100mg tablet daily. Depending on your initial response, your doctor may adjust your dosage after 1 to 2 weeks or prescribe other medicines for high blood pressure in combination with this therapy.
Angina: 1 x 100mg tablet, once a day or 1 x 50mg tablet, twice a day.
Disturbances of heart rhythm (dysrhythmias): Once your heart rhythm is controlled, 1 x 50mg or 1 x 100mg tablet daily may be given to control your condition.
Heart attack (myocardial infarction): If you suffered a heart attack within the last 12 hours you may have had a slow atenolol injection into a vein. Fifteen minutes after the injection 1 x 50mg Atenolol Tablet may be given, followed by a further 50mg tablet 12 hours after the injection. Twelve hours after the second tablet, 1 x 100mg tablet may be given. Thereafter, 1 x 100mg tablet should be taken once a day.
Elderly patients or those with kidney problems:
If you are elderly, or have kidney problems, the above adult dosages will probably be reduced.
If you have kidney problems your dosage will depend on your body’s rate of clearance/blood levels of creatinine, which is derived from the muscle. If you have a creatinine clearance of 15ml to 35ml/minute/1.73m (equivalent to creatinine in the blood of 300 to 600 micromol/litre) you will be prescribed a dose of 50mg daily. If you have a creatinine clearance of less than 15ml/minute/1.73m (equivalent to creatinine in the blood of greater than 600 micromol/litre) your dose will be 50mg to be taken on alternate days. Patients on dialysis should be given 50mg after each dialysis under hospital supervision.
Children:
Atenolol Tablets are not recommended for children.
DO NOT stop taking the tablets without consulting your doctor as withdrawal may lead to worsening of the basic conditions. The tablets should be withdrawn gradually.
If you have accidentally taken one extra dose, this is unlikely to be a cause for concern. However if you or someone else has taken more than one extra dose or a large overdose, contact your doctor or local hospital accident and emergency department.
If you have forgotten to take your medicine, take it as soon as you remember and your next dose at the usual time. Do not take two doses at the same time. If your next dose is due within 6 hours, do not take the missed dose, but take the next dose at the usual time. If you are concerned, consult your doctor or pharmacist.
As with all medicines you may experience some unwanted effects whilst taking Atenolol Tablets including slow heart beat, a worsening of an existing heart block, low blood pressure, heart failure, cold/bluish-looking fingers and/or toes, Raynaud’s phenomenon (where the arteries of the fingers go into spasm when the hands are cold, symptoms of this are numb, uncomfortable, pale fingers), pins and needles, and an intermittent leg cramp induced by exercise but relieved by rest.
In addition, reports of fatigue, headaches, impaired vision, hallucinations, psychoses, confusion, dizziness, sleep disturbances, nightmares, depression or impotence have been made.
Rarely, gastro-intestinal problems may occur such as nausea, vomiting or diarrhoea.
Difficulties with breathing including wheezing may occur in patients with asthma or who have a history of asthmatic complaints or breathing difficulties. Skin disorders have been reported, especially rash and dry eyes. If you have any of these after starting to take atenolol see your doctor as your medication may need to be reviewed.
Atenolol, in common with other beta-blockers, may mask the symptoms of hypoglycaemia (low blood sugar) and thyrotoxicosis (where there is an excessive amount of thyroid hormones in the blood). If you are worried about either of these, discuss it with your doctor.
If you have any of these effects and they become severe or upsetting, or you experience any other unpleasant effects which you think could be due to taking Atenolol Tablets, you should contact your doctor or pharmacist for advice.
