Part of a class of medications known as antihistamines, meclizine hydrochloride (Antivert®, Bonine®, Dramamine® Less Drowsy Formula) is used for treating vertigo and motion sickness. Even though most people do not experience any problems while taking this drug, risks associated with meclizine should be reviewed before you begin treatment.
Some side effects with meclizine are potentially serious and should be reported immediately to your healthcare provider. Although generally rare, some of these side effects may actually be fairly common, particularly in young children or the elderly. These include, but are not limited to:
- Heart palpitations
- A rapid heart rate (tachycardia)
- An irregular heartbeat
- Difficulty passing urine
- Worsening of ulcers or gastroesophageal reflux disease
- Worsening of glaucoma.
You may be at an increased risk for developing side effects if you are over 60 years old. It is recommended that elderly people check with their healthcare providers before taking this drug. You should also consult your healthcare provider before using meclizine if you have hyperthyroidism, heart disease, or high blood pressure (as the drug may worsen these conditions).
