Which side effect might indicate a negative reaction to mood stabilizers?

Fine hand tremors are a known side effect associated with the use of mood stabilizers, particularly lithium, which is commonly prescribed for mood stabilization. These tremors can indicate that the medication is affecting the nervous system, leading to a negative reaction. Monitoring for tremors is essential, as they may suggest that the dosage needs adjustment or that the medication may not be suitable for the individual.

In contrast, heightened appetite might come from a variety of factors and isn't typically indicative of a negative reaction. Increased clarity of thought and improved sleep patterns are generally considered positive responses to mood stabilizers, suggesting that the medication is functioning as intended to enhance cognitive function and regulate sleep.
