Before generic Desenex cream can be prescribed, the patient and their local doctor must take into consideration the risks and benefits that usage of this drug will bring about. For instance, it should be discussed whether you have ever had any abnormal or allergic reaction to this medication in particular or any other medications in general. Your local physician must also be aware if you have any other types of allergies, such as to foods, dyes, preservatives, or animals, or if you are taking any other drugs, whether they are prescription drugs or over the counter meds, so any possible interactions are taken into account when you buy Desenex.
