A member asked:
If a person use propranolol 10mg for a long time, can the drug lose its effect on him (like antibiotics, something like body resistance)?
A doctor has provided 1 answer
Unlikely: It's rare for someone to develop resistance to such a medication. However, there are normal physiologic changes that take place which make it possible for a medication to not work quite as well. Sometimes the dose has to be increased.
