I have noticed black discolouration on my tongue and penis after taking Neurobion Forte Tablet for a week. Does this mean it is not suitable for me?
Black discolouration of the tongue or genital area is not a known side effect of Neurobion Forte Tablet. The supplement is generally well tolerated, and side effects at the recommended dose are rare and usually mild, such as minor stomach upset. It is advisable to stop the supplement temporarily and consult your doctor for a proper evaluation to rule out any underlying conditions and to determine whether it is safe for you to continue.
