Meclizine is a popular over-the-counter (OTC) medication for motion sickness and dizziness.
While effective, it can cause side effects that users should understand. This article explores meclizine OTC side effects to help you use it safely.
What Is Meclizine?
Meclizine is an antihistamine used to relieve motion sickness and vertigo. It’s sold under brands like Bonine and Dramamine Less Drowsy. Available without a prescription, it’s taken by adults and children over 12.
It works by calming the inner ear and brain signals causing nausea. Most people tolerate it well. However, side effects can occur with improper use.
Why Use Meclizine OTC?
Meclizine is widely available at pharmacies and stores. It’s affordable and effective for preventing nausea during travel or vertigo episodes. Tablets or chewables make it easy to use.
Understanding meclizine OTC side effects ensures safe use. It’s ideal for occasional symptoms. Always follow dosing instructions to minimize risks.
How Meclizine Works
Meclizine blocks histamine receptors in the brain. This reduces signals that trigger nausea and dizziness. It’s most effective when taken before symptoms start.
Effects last up to 24 hours, making it great for long trips. It’s not a cure for underlying conditions. Side effects may arise from its sedative properties.
Common Meclizine OTC Side Effects
Meclizine is generally safe, but side effects can occur. Most are mild and temporary. Knowing these helps you manage or avoid them.
Drowsiness
Drowsiness is the most common side effect of meclizine. It can make you feel sleepy or sluggish. This is due to its antihistamine properties.
Avoid driving or operating machinery after taking it. Use at night if drowsiness is a concern. The effect varies by person.
Dry Mouth
Dry mouth is another frequent side effect. It happens because meclizine reduces saliva production. This can feel uncomfortable but is usually mild.
Sip water or chew sugar-free gum to ease it. Avoid caffeine, which worsens dryness. The symptom often fades with time.
Blurred Vision
Some users experience blurred vision temporarily. This occurs as meclizine affects the nervous system. It’s usually mild and short-lived.
Avoid activities requiring clear vision, like reading, if affected. Rest your eyes until it passes. See a doctor if it persists.
Fatigue
Fatigue or feeling tired can occur with meclizine. It’s related to its calming effects on the brain. This may impact daily energy levels.
Take it when you can rest, like before bed. Avoid combining with other sedatives. Rest usually helps this side effect.
Headache
Headaches are less common but possible. They may result from meclizine’s effect on the nervous system. Staying hydrated can help reduce this.
Take the recommended dose to avoid worsening. Rest in a quiet space if a headache occurs. Consult a doctor if severe.
Less Common but Serious Side Effects
Rare side effects of meclizine can be more serious. These require attention if they occur. Here are a few to watch for.
- Confusion: Some users, especially older adults, may feel confused. This is rare but can affect focus or memory. Stop use and consult a doctor if noticed.
