If crystals have precipitated in the detreomycin solution, can it have any negative consequences?

The crystals that appeared in the solution are Detreomycin, which will make the drug work weaker. If you have not used much of the solution, I suggest removing the bottle from the refrigerator and you can continue the therapy when detreomycin dissolves (it is worth stirring before the first use). It must be stored at room temperature, in a lockable cabinet. Preferably in the room and outside the access of children, not in the kitchen (where it is warmest) and not in the bathroom (where there is the highest humidity). The solution is on alcohol, so you can easily use it for up to 3 months.
