When two or more medicines
are taken together, it can change how the medicines work and increase the risk of side-effects. In medical terms, this is called as a Drug Interaction
interacts with disopyramide
, which is used in the treatment of irregular heartbeat. The patients who use Atenolol
in combination with disopyramide are at an increased risk to develop severely reduced heartbeat, lack of tissue contraction
from the heart muscles (asystole), and heart failure.
There may be an interaction of Atenolol
channel blockers, which are used to treat high blood pressure. Patients who are on treatment with Atenolol
along with calcium
channel blockers such as verapamil
are at an increased risk of reduced heartbeat and heart block as well as left ventricular end diastolic pressure, which is an important measure of ventricular performance. Particularly the patients with existing problems with conduction of heart are at increased risk.
may interact with catecholamine-depleting drugs such as reserpine
, which is used to treat high blood pressure and mental illness (psychosis
). Reserpine has an additive effect when given in combination with Atenolol
and may result in low blood pressure and reduced heartbeat that can further lead to vertigo
, and fall in blood pressure when a person stands. Patients who are on treatment with both Atenolol
and reserpine should be monitored carefully for these side-effects
Your doctor's guidelines may need to be followed while taking this medicine along with clonidine
, which is used to treat a variety of problems such as high blood pressure, anxiety
, and certain pain
conditions. The patients who are on both beta blockers and clonidine may experience rebound high blood pressure during withdrawal of clonidine. When beta blockers such as Atenolol
is given in combination with clonidine, the withdrawal of beta blockers should be done several days before the withdrawal of clonidine. If clonidine is to be replaced by beta-blocker
therapy, the starting therapy of beta-blockers should be postponed for some days after the use of clonidine is stopped.
Special instructions need to be followed while taking this medicine along with amiodarone
, which is used to treat increased or decreased heartbeats. Use of Atenolol
with amiodarone may have an enhancing effect on conduction of the electrical impulses throughout the atria of the heart and induce the weakening of heart muscle contractions.
Your doctor's guidelines may need to be followed while taking this medicine along with insulin
, which is used to treat high blood sugar
levels. Use of Atenolol
and other antidiabetic drugs may result in increased blood sugar
lowering effects of these drugs. Also, the symptoms of lowered blood sugar (hypoglycemia
) and increased heartbeat may be masked. Take necessary precautions while using Atenolol
in diabetic patients.
Special instructions need to be followed while taking this medicine along with adrenaline
, is a neurotransmitter which is used to treat serious allergic symptoms. The patients who are on treatment with Atenolol
may experience a decrease in blood lowering effect of Atenolol
interacts with dihydropyridines such as nifedipine
, which is used to manage chest pain
and high blood pressure. Patients who are on treatment with Atenolol
are at an increased risk of low blood pressure, heart failure in patients with the insufficient flow of blood.
There may be an interaction of Atenolol
with digitalis glycosides, which are used to increase the force of the heart and decrease its rate of contractions. Patients who are on treatment with Atenolol
and digitalis glycosides are at an increased risk to develop reduced heartbeats, slow atrioventricular conduction and decreased heart rate.
may interact with prostaglandin synthase blocking drugs such as indomethacin
, which is used to treat pain
, swelling, fever
and inflammation. The use of prostaglandin synthase preventing
drugs in patients who are on therapy with beta blockers such as Atenolol
may result in decreased blood pressure lowering effect.
may interact with anesthetic
agents, which are used to produce a temporary loss of sensation. Use of beta-blockers
with anesthetic drugs may result in increased risk of fast heartbeat and low blood pressure conditions. Such patients should use caution while selecting an anesthetic. Anesthetist should be informed that the patient is on treatment with Atenolol
and the anesthetic must be an agent that has little weakening action on contractions of heart (negative inotropic activity) as possible.
