Can Atenolan cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with Atenolan. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
7. Pregnancy and breastfeeding
Atenolan is not usually recommended in pregnancy.
If you're trying to get pregnant or already pregnant, talk to your doctor about the benefits and possible harms of taking Atenolan.
There may be other medicines that are safer for you. Labetalol is a similar medicine that's often recommended for high blood pressure in pregnancy.

What are metoprolol and Atenolan?
Metoprolol is a beta-blocker (beta-adrenergic blocking agent), which blocks the action of the sympathetic nervous system (a portion of the involuntary nervous system) and is used to treat high blood pressure (hypertension), heart pain (angina), congestive heart failure, hyperthyroidism, abnormal heart rhythms, and some neurologic conditions. Metoprolol is also used to prevent migraine headaches.
Atenolan is a beta-blocker that blocks the effects of adrenergic chemicals such as adrenaline or epinephrine, which are released by nerves of the sympathetic nervous system. The beta-adrenergic nerves stimulate the heart muscle to beat more rapidly. By blocking the stimulation by these nerves, Atenolan reduces the heart rate and is used to treat abnormally rapid heart rhythms. Atenolan also reduces the force of contraction of heart muscle and lowers blood pressure. By reducing the heart rate, the force of muscle contraction, and the blood pressure against which the heart must pump, Atenolan reduces the work of heart muscle and the need of the muscle for oxygen, which helps in treating angina.
Use with caution in anesthesia or surgery (myocardial depression), bronchospastic disease, cerebrovascular insufficiency, diabetes mellitus, hyperthyroidism or thyrotoxicosis, liver disease, renal impairment, peripheral vascular disease, compromised left ventricular function, advanced age, heart failure.
May mask effects of hyperthyroidism.
Risk of hypoglycemia and bradycardia in neonates born to mothers who receive the drug at parturition or while breastfeeding, especially in premature infants and those with renal impairment.
Use with caution in patients taking calcium-channel blockers or cardiac glycosides or using inhaled anesthetics.
Avoid abrupt withdrawal; sudden discontinuance can exacerbate angina and lead to MI.
Increased risk of stroke after surgery.
In patients receiving clonidine, Atenolan should be discontinued several days before withdrawal of clonidine.
May cause or exacerbate CNS depression (use with caution in patients with psychiatric illness).
Use in pheochromocytoma (alpha blockade required before use of beta blocker).
Consider preexisting conditions such as sick sinus syndrome before initiating therapy.
May potentiate hypoglycemia and may mask its signs and symptoms in patients with diabetes mellitus; use caution.
Monitor for worsening of heart failure symptoms in patients with compensated heart failure.
Use caution in patients with myasthenia gravis; may precipitate or aggravate symptoms or arterial insufficiency in patients with Raynaud's disease and peripheral vascular disease; use caution and monitor for progression of arterial obstruction.
Avoid beta-blockers without alpha1-adrenergic receptor blocking activity in patients with Prinzmetal variant angina; unopposed alpha1-adrenergic receptors mediate coronary vasoconstriction and can worsen anginal symptoms.
Exacerbation or induction of psoriasis reported with beta-blocker use; cause and effect not established.
Rated Atenolan for Hypertension Report
I started Atenolan about 3 yrs ago for hypertension and irregular heartbeat. Until just recently it worked perfectly. Really lowered my BP to healthy level. But my pulse went way down to 60 and I’d have cold extremities. Now, within the last couple of months, very achy and weak knees, a little thigh muscle pain. Also starting to feel right side back pain. Recent physical all fine except beginning decreased kidney function. So I’m not waiting. Throwing caution to the wind I’m getting off this drug before severe damages set in.
Pharmacologic class: Beta-adrenergic blocker (selective)
Therapeutic class: Antianginal, anti-hypertensive

Why is this medication prescribed?
Atenolan is used alone or in combination with other medications to treat high blood pressure. It also is used to prevent angina (chest pain) and improve survival after a heart attack. Atenolan is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
Urgent advice: Call your doctor or go to A&E straight away if you take too much Atenolan
If you take more than the prescribed dose, your heart rate may slow down and you may find it difficult to breathe. It can also cause dizziness and trembling.
If you need to go to hospital, do not drive yourself. Get someone else to drive you or call for an ambulance.
Take the Atenolan packet or leaflet inside it, plus any remaining medicine, with you.
Like all medicines, Atenolan can cause side effects in some people, but many people have no side effects or only minor ones.
Side effects often improve as your body gets used to the medicine.

I was prescribed this medication for high blood pressure. I felt better not long after I took the first dose. It also helps greatly with my anxiety. I am terrified of new medications, but have noticed zero side effects personally. I have been taking it almost a year.
