Background: Controlled trials suggest that clomipramine may be a highl
y effective antipanic drug. Lowering the starting dose may alleviate t
roublesome initial side effects and increase acceptability and complia
nce. Method: Fifty-eight patients with DSM-III-R panic disorder with o
r without agoraphobia underwent 13 weeks of clomipramine treatment. St
arting at 10 mg/day, the dose was gradually increased to a mean dose o
f 97 mg/day. Results: While completers showed highly significant impro
vement, the benefits were severely limited by a high dropout rate due
to adverse reactions occurring mostly during the first 2 weeks of trea
tment. Conclusion: Given the alternatives, clomipramine should not be
used as a first-line antipanic medication.
