Increasing the dose or duration of treatment (or in some cases, decreasing) may not be beneficial and may be harmful.
Changing treatment approaches may increase potential harms without increasing efficacy.
Although it may appear logical that increasing the amount of a drug prescribed should increase its positive effect, this is not always true. Increasing the dose/amount of treatment may increase or introduce negative effects rather than have a positive effect. The standard prescription amounts are often already set at the peak positive effect level, so a higher dose/duration can only potentially add negative side effects.
It is also important to consider any legal ramifications of increasing dosage such as its effect on withdrawal periods in production animals.
BEWARE of altering treatment approaches based on simple linear relationships and not scientific evidence.
REMEMBER: More is not necessarily better.
