Tenormin is known as a beta blocker. That means the drug works in part by blunting the action of adrenaline, the body's natural fight-or-flight chemical.
People normally respond to stressful situations with a rapid pulse, a pounding heart and an increase in blood pressure. Tenormin helps block such reactions.
This medicine is normally prescribed for high blood pressure, chest pain caused by angina, or heart attack.
Although the FDA has not specifically approved its use for other purposes, doctors sometimes prescribe Tenormin to treat irregular heart rhythms and performance anxiety such as stage fright.
It has also been used to help prevent migraine headaches. The dose will vary depending upon the condition being treated.
Tenormin can cause a number of side effects. They include slow heart rate, cold hands and feet, tiredness, nightmares, blurred vision, sexual difficulties, nerve tingling, dizziness, nausea, stomach ache, gas, diarrhea, indigestion, rash, arthritis and muscle pain.
This medicine may also have a negative effect on cholesterol and other blood fats, so a lipid test before treatment and periodically thereafter would be prudent.
Although Tenormin is a little less likely to affect the nervous system than certain other drugs in this class, be alert for the beta blocker blahs.
Symptoms of psychological depression, fatigue, decreased concentration, memory loss and mood swings may come on slowly and insidiously.
Notify your physician promptly of any adverse reactions, especially breathing difficulties, fluid retention in the legs or a night cough.
These drugs may make treatment of diabetes and thyroid disorders more complicated. Check with your physician about
Some people must be very careful if they take beta blockers.
Asthmatics and patients with other respiratory problems are especially vulnerable as these drugs can make breathing worse.
Tenormin is a little better than other beta blockers in this regard, but monitor your breathing carefully.
People with heart failure must also be extremely cautious if prescribed beta blockers, as the medicine could occasionally lead to cardiac complications.
Tenormin can be taken at meal time or on an empty stomach. If you find this medicine causes digestive tract upset, it may be better tolerated when taken with food.
Because of its relatively long action in the body, Tenormin offers the convenience of once-daily dosing.
Don't take calcium supplements or antacids at the same time as Tenormin, as they may reduce its absorption.
Never stop taking Tenormin suddenly.
Your doctor must phase you off gradually to prevent serious heart problems.
