The necessity for discontinuation of therapy due to undesirable effects has been rare with serapax. Transient, mild drowsiness is commonly seen In the first few days of therapy. If it persists, the dosage should be reduced. In few instances, dizziness, vertigo, headache, and rarely syncope have occurred either alone or together with drowsiness.Other side effects occurring during oxazepam therapy include rare instances of nausea, lethargy, edema, slurred speech, tremor, altered libido, and minor skin rashes.Hope this helps.Take care.
