Nu Atenol Dosage

The recommended adult dose of Nu Atenol (Atenolol) ranges from 50 mg to 200 mg daily depending on circumstances. 

To treat high blood pressure, the usual adult starting dose is 50 mg taken by mouth, once a day. The full effect of the medication is usually reached within 1 to 2 weeks. If blood pressure is not reduced sufficiently after this time, your doctor may increase the dose of the medication to 100 mg once daily or add another blood pressure-lowering medication.

The usual starting dose to treat angina pain is 50 mg taken once a day. If, after one to two weeks symptoms are not reduced enough, your doctor may increase the dose to 100 mg once daily or 50 mg taken twice a day. The maximum dose for treating angina is 200 mg daily.

If you have reduced kidney function you may need much lower doses.

Nu Atenol Precautions

There may be an interaction between Nu Atenol (Atenolol) and any of the following:

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Nu Atenol (Atenolol). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Nu Atenol Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Nu Atenol (Atenolol).

Breathing conditions: In general, people who have Asthma and certain other breathing problems or chronic lung disease should avoid taking a beta-blocker such as Nu Atenol (Atenolol), as it can cause breathing difficulty. Low doses of Nu Atenol (Atenolol) may be taken with caution by people with asthma who do not respond to or cannot tolerate alternative treatment. If you have breathing problems, discuss with your doctor how Nu Atenol (Atenolol) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nu Atenol (Atenolol), and whether any special monitoring is needed.

Drowsiness/reduced alertness: The use of Nu Atenol (Atenolol) is unlikely to impair your ability to drive or operate machinery. However, it should be taken into account that dizziness, fatigue, or a slower reaction time may occur.

History of heart failure: Beta-blockers, such as Nu Atenol (Atenolol), can worsen existing heart failure. It is important to take Nu Atenol (Atenolol) exactly as prescribed by your doctor to decrease the chance of this happening. If you have a history of heart disease, discuss with your doctor how Nu Atenol (Atenolol) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nu Atenol (Atenolol), and whether any special monitoring is needed.

Hyperthyroidism: If you have hyperthyroidism (high levels of Thyroid hormones) you should use caution while taking Nu Atenol (Atenolol), as it may reduce the symptoms of this condition, giving a false impression of improvement. Stopping the medication suddenly could worsen this condition.

Kidney Disease: The kidneys are partially responsible for removing Nu Atenol (Atenolol) from your body. Kidney disease or reduced kidney function may cause Nu Atenol (Atenolol) to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how Nu Atenol (Atenolol) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nu Atenol (Atenolol), and whether any special monitoring is needed.

Low blood sugar: The signs of low blood sugar may not be as noticeable when taking Nu Atenol (Atenolol). If you have Diabetes and take insulin or other medications that affect insulin levels in the blood, discuss with your doctor how Nu Atenol (Atenolol) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nu Atenol (Atenolol), and whether any special monitoring is needed. Your doctor will monitor you while you are taking Nu Atenol (Atenolol) and may need to adjust the doses of diabetes medications.

Prinzmetal's angina: Nu Atenol (Atenolol) may increase the number and duration of angina attacks in patients with Prinzmetal's angina. If you have this condition, be cautious while taking Nu Atenol (Atenolol). Report unusual chest pain to your doctor as soon as possible.

Severe allergies: If you have allergies severe enough to cause Anaphylaxis (severe allergic reaction) (a severe allergic reaction where swelling of the face, lips, and throat make it difficult to breathe), you should talk to your doctor about what to do if you have an allergic reaction. Nu Atenol (Atenolol) may make it more difficult to treat your allergic reaction with Epinephrine.

Slow heart rate: In general, people with an abnormally slow pulse should not take a beta-blocker such as Nu Atenol (Atenolol).

Stopping usage: Nu Atenol (Atenolol) should not be stopped suddenly. There have been reports of severe worsening of angina and of Heart Attack or abnormal heart rhythms occurring in people with angina pectoris who have done this. If Nu Atenol (Atenolol) needs to be stopped, it should be done gradually under supervision of your doctor.

Surgery: If you are scheduled for surgery, inform all doctors involved in your care that you are taking Nu Atenol (Atenolol).

Pregnancy: Studies have shown that Nu Atenol (Atenolol) does cross the placenta and there have been reports of harm to the developing baby if Nu Atenol (Atenolol) is taken by the mother during pregnancy. Nu Atenol (Atenolol) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Nu Atenol (Atenolol), contact your doctor immediately.

Breast-feeding: Nu Atenol (Atenolol) passes into breast milk. If you are a breast-feeding mother and are taking Nu Atenol (Atenolol), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Nu Atenol (Atenolol) have not been established for children.
