Is Propranolol Fattening?

To learn about Propranolol, we decided to take a look at the list of adverse reactions listed in the package leaflet.

The document has no direct effect that could lead us to conclude that Propranolol is fattening. However, two of their common adverse reactions are fatigue and lassitude, which is synonymous with exhaustion.

They are classified as common effects of being tried with the product, that is, observed between 1% and 10% of patients who use the drug.

Indirectly, this tiredness brought about by the medication can cause the person to exercise less and stay less active, which can lead to a reduction in the amount of calories spent on the day day.

As we all know, this can facilitate weight gain. However, this does not necessarily mean that Propranolol is fattening, only that it has effects that indirectly contribute to weight gain and these effects are felt only by users.

It is only a hypothesis, a possibility of something that can happen or not with a patient suffering from fatigue and exhaustion when using the medicine.

In addition, when an Internet user asks if Propranolol is fattening, cardiologists Fabio Gomes da Conceição, Luis Fernando Barone and Marco Túlio Villaca Castagna answered that the remedy does not cause the increase of weight.

Thus, we can not state that Propranolol is fattening. Therefore, when you realize that you gained weight when using the medication, talk to your doctor to find out what may have caused weight gain and whether or not this is associated with the use of the medicine.
