| Nausea
& Vomiting
Persistent nausea can often be effectively controlled
by using a combination of medications tailored
to meet that individual’s specific needs.
Dosage forms include transdermal gels, suppositories,
lollipops, and more.
Promethazine is commonly compounded
for topical or transdermal application to treat
nausea, vomiting, and vertigo, but this preparation
may be used as an antiemetic for cases ranging
from chemotherapy to motion sickness. The dose
is typically 25mg for adults, and the dose is
decreased for children. The gel is applied to
an area of soft skin, such as the inside of the
wrist or arm, the side of the torso, or the inside
of the thigh. For children, doses are often applied
to the inside of one wrist, and then the wrists
are rubbed together.

Lorazepam, diphenhydramine, haloperidol,
and metoclopramide (known in combination
as "ABHR") have been prepared as a rectal
suppository and in other transdermal dosage forms.
The rationale is to use a variety of medications
which target various pathways such as vagal nerve
stimulation, the vomiting center, and the CTZ
for more severe cases. Researchers at Memorial
Sloan-Kettering Cancer Center have studied the
antiemetic activity and safety of the antiemetic
regimen of metoclopramide, dexamethasone, and
diphenhydramine in patients receiving standard
outpatient chemotherapy programs. Vomiting was
prevented in over 70% of patients.

Intranasal metoclopramide may significantly reduce
the frequency of acute vomiting in patients receiving
highly emetogenic chemotherapy, such cisplatin-induced
delayed emesis. Intranasal metoclopramide caused
minor irritation of the nasal membrane and unpleasant
taste in some patients, but was otherwise well
tolerated, with no report of serious extrapyramidal
effects.
