Atenolol - Overview
Atenolol is sometimes prescribed to people for the treatment of hypertension (high blood pressure) and chest pain, and to improve outcomes after a heart attack. Push Health connects people in need of an atenolol prescription with medical providers who can prescribe atenolol (25 mg, 50 mg or 100 mg tablets), when appropriate to do so.
What Is Atenolol Used For?
Atenolol prescription medication is available as a low-cost generic and was originally marketed under the brand name Tenormin. Atenolol belongs to a class of drugs known as cardioselective beta-1 blockers and is similar to metoprolol (Lopressor, Toprol) although there are some pharmacokinetic differences. Atenolol medication is widely used as it has very little in the way of intrinsic sympathomimetic activities. A synthetic medication, atenolol tablets have been observed to cause a reduction in heart rate, cardiac output, blood pressure and reflex orthostatic tachycardia.
Atenolol is more cardioselective than non-selective beta blockers such as propranolol (Inderal) and carvedilol (Coreg). Atenolol is also combined with chlorthalidone in a medication called Tenoretic.
Atenolol - Dosage and Cost
Atenolol dosing depends on the condition being treated and the unique needs of the patient but certain protocols are used as guidelines:
- Hypertension: often start at 50 mg once daily; usual range 50-100 mg once daily
- Angina: commonly 50-100 mg once daily (maximum usually 200 mg/day)
- Post-MI: dosing is determined in the acute setting and may continue long-term
Atenolol tablets are available in 25 mg, 50 mg and 100 mg tablets. Generic atenolol is very inexpensive, often costing under 10-20 cents per tablet. Atenolol savings cards may also help with costs associated with atenolol tablets.
Can I Buy Atenolol Online?
Atenolol is a prescription medication and is not available over the counter. Through Push Health, patients can complete an online evaluation with a licensed medical provider who can prescribe atenolol when appropriate to do so. Atenolol medication is typically available at more retail and delivery pharmacies.
Frequently Asked Questions about Atenolol
Is atenolol the same as Tenormin?
Yes. Tenormin is the original brand name. Generic atenolol contains the same active ingredient and is bioequivalent. Most pharmacies dispense the generic.
How does atenolol compare with metoprolol?
Both are cardioselective beta-1 blockers and are effective for blood pressure and angina. Metoprolol has more liver metabolism and comes in immediate- and extended-release forms; atenolol is once-daily for most patients and is renally cleared. Choice depends on individual factors, other conditions, and provider preference. Neither is usually first-line for hypertension alone under current guidelines.
What are the most common side effects?
Fatigue, dizziness, slow heart rate (bradycardia), low blood pressure, cold extremities, and sometimes sexual dysfunction or sleep changes. Most side effects are dose-related.
Can I stop atenolol suddenly?
No. Abrupt discontinuation of beta blockers can worsen angina or increase the risk of heart attack in susceptible patients. The dose should be tapered under medical supervision.
Who should not take atenolol?
Atenolol is generally avoided in patients with severe bradycardia, second- or third-degree heart block, cardiogenic shock, or overt/decompensated heart failure. Caution is also needed in asthma/COPD, diabetes (may mask low blood sugar symptoms), and significant renal impairment.
Does atenolol interact with alcohol?
Alcohol can enhance blood-pressure-lowering and dizziness effects. Moderate use should be discussed with a provider; heavy use is best avoided.
How long does atenolol take to work for blood pressure?
Some reduction in blood pressure can be seen within hours, but the full effect of a given dose is usually assessed after 1-2 weeks of consistent use.
Atenolol - Side Effects
Atenolol prescription tablets can cause side effects such as weakness, fatigue, dizziness, low heart rate and blood pressure, and cardiac dysfunction when used. More serious side effects can also occur:
- Worsening of heart failure or heart block in susceptible patients
- Masking of hypoglycemia symptoms in people with diabetes
- Possible bronchospasm in patients with reactive airway disease
- Risk with abrupt withdrawal
