Motion sickness is an important problem for many pets and while there are presently several medications with ability to relieve discomfort and nausea associated with motion sickness, each has pros and cons. Sometimes sedation is desired for the travel period and sometimes it is not. Acepromazine, for example, lasts for 6-8 hours but is very sedating. Some medicines, such as maropitant, require an hour or more for their effect to "kick in." Meclizine provides a relatively short-acting effect with minimal sedation and, even though it is a human medication, it has proved to be quite helpful for nausea relief associated with motion sickness.
HOW THIS MEDICATION IS USED
Meclizine hydrochloride is generally used for nausea relief due to motion sickness. It is also used to control the nausea resulting from vestibular disease, a syndrome characterized by vertigo and loss of balance.
For the prevention of motion sickness, meclizine hydrochloride should be given approximately 30 minutes before travel. Anti-nauseal effects can be expected to last approximately 6 hours. Meclizine hydrochloride can be given with or without food.
If a dose is accidentally skipped, do not double up on the next dose. Simply give the medication when it is remembered and be sure to wait at least 6-8 hours before the next dose.
Meclizine hydrochloride is a member of the piperazine class of antihistamines. It may produce some drowsiness though nothing like the 6 to 8 hours of tranquilization yielded by its cousin, acepromazine.
Most antihistamines have potential to cause any of a group of symptoms referred to as anticholinergic symptoms: urinary retention, dry mouth, dry eyes, increased heart rate, and exacerbation of glaucoma (elevated pressure within the eye). It may also reduce the ability to produce milk in lactating mothers.
INTERACTIONS WITH OTHER DRUGS
Meclizine hydrochloride should not be given in conjunction with other tranquilizing drugs as such a combination may lead to excess sedation. Similarly, it should not be given in conjunction with other antihistamines nor with tricyclic antidepressants such as fluoxetine (Prozac®) so as to minimize the potential for the unpleasant (anticholinergic) side effects listed above.
Meclizine can reduce the effectiveness of GI motility modifiers such as metoclopramide and cisapride.
