In case of concomitant use other drugs or supplements, the effectiveness of Inderal may change. The patient is required to inform the physician about taken drugs, vitamins, and nutritional supplements. This information will allow the doctor to make the corresponding treatment course, which will avoid negative interactions.
Inderal may interact with the following drugs and products:
Propranolol strengthens (mutually) the negative impact of Verapamil and Diltiazem on the myocardium, prolongs the action of non-depolarizing muscle relaxants, and inhibits the excretion of lidocaine. Heparin, antacids lower plasma levels of this medication and Cimetidine and phenothiazines – increase. Concurrent use with monoaminooxidase inhibitors is not recommended. It slows down the metabolism of Theophylline and increases its concentration in the blood plasma.
Ethyl alcohol, which is part of the alcoholic beverages can interact with drugs both at the stage of their distribution in the body, and in the process of their metabolism (transformation). Such effects can weaken or enhance the effect of drugs and provoke the development of undesirable side reactions, which can be extremely serious.
Compatibility of this substance with alcohol is very low. Their concomitant use is dangerous. Reviews of some patient relatives indicate that quite often the result of the concomitant use of Propranolol and alcohol is fatal. This indicates on an extremely high risk of taking this active ingrdient after alcohol. First of all, this combination can lead to the fact that blood pressure drops to a critically low level. The medical definition of such a condition is orthostatic collapse. The condition is manifested by a sharp decrease in pressure, for example, when a person gets up. Usually such a condition is accompanied by nausea, chills, weakness, cooling of the limbs and a lack of coordination.
The greater the amount of alcohol consumed by the patient, the lower the blood pressure can be. In addition, alcohol can greatly enhance the manifestations of side effects from taking the drug. There can be hypotension or even faint.
Hypotension is accompanied by headaches and dizziness, nausea, drowsiness, etc. If Propranolol is prescribed to treat hypertension or tachycardia, then its effectiveness will be reduced to nothing if the person consumes alcohol along with treatment course.
When being under treatment course with Propranolol, it is necessary to abandon the alcohol intake even in minimal doses. This can affect the work of almost all internal organs and body systems.
Thus, it is dangerous to underestimate the possible consequences of the co-administration of this drug and alcohol as it may lead to fatal results. It has to be remembered that the spectrum of the harmful impacts of alcohol on the body is so wide that it is almost impossible to predict all the consequences of such a combination.
The feedback is mostly positive. The users and physicians report that drug treatment is often effective. In addition, many are satisfied with the low price of medication. Inderal maintains blood pressure at a normal level, quickly eliminates heart palpitations. The drug reduces the manifestations of heart disease, relieves a person from agitation.
