A drug or a vaccine from reputed brands which are market leaders for treating diseases may create dependence with high prescription value. However, there are situations when stocks of these particular brands may not currently be available in medical shops.
And in that cases, shopkeepers often show similar drugs/vaccines with similar dose/units of a different brand which may not be a popular one. In such situations, would you recommend the biosimilars of a different brand or stick to the reputed market leader?
