Navigating the world of over-the-counter and prescription medications requires caution, especially when considering combining them. A common question that arises is about the safety of mixing a prescription anxiety and allergy medication with a popular motion sickness remedy. It is generally advised to avoid taking hydroxyzine and Dramamine together due to the increased risk of significant side effects [1.2.1]. Both medications are first-generation antihistamines, which are known to cross the blood-brain barrier and cause sedation [1.3.3, 1.5.4]. Combining them potentiates these effects, leading to a state of enhanced central nervous system (CNS) depression [1.2.3].
What is Hydroxyzine?
Hydroxyzine is a prescription medication classified as a first-generation antihistamine [1.3.3]. It works by blocking histamine receptors in the body. While it's used for treating allergic reactions like itching and hives, it's also prescribed for anxiety [1.2.6, 1.4.8]. Its effectiveness in treating anxiety stems from its sedative properties, which help to calm the central nervous system [1.2.3]. However, these same properties contribute to its side effect profile, which includes drowsiness, dry mouth, and dizziness [1.6.1]. Hydroxyzine also has strong anticholinergic properties, meaning it blocks the neurotransmitter acetylcholine, which can affect memory, concentration, and other bodily functions [1.3.4, 1.6.1].
What is Dramamine?
Dramamine, with its active ingredient dimenhydrinate, is a well-known over-the-counter medication used primarily to prevent and treat nausea, vomiting, and dizziness associated with motion sickness [1.6.8]. Like hydroxyzine, dimenhydrinate is a first-generation antihistamine and possesses anticholinergic properties [1.3.3, 1.6.8]. It works by affecting the inner ear's vestibular system and the brain's vomiting center. Its sedating effect is a common side effect, which is why it's often labeled as 'drowsy' formula [1.4.6].
The Dangers of Combining Hydroxyzine and Dramamine
When you ask, Can you take hydroxyzine with Dramamine?, the primary concern is the amplification of adverse effects. Because both drugs belong to the same class and act on the body in similar ways, taking them together leads to an additive effect [1.3.1].
Additive Sedation and CNS Depression
Both hydroxyzine and Dramamine are CNS depressants [1.2.3, 1.3.9]. When taken together, their sedative effects are magnified. This can lead to:
- Excessive Drowsiness and Sedation: This can impair your ability to perform tasks that require mental alertness, such as driving or operating heavy machinery [1.2.1, 1.4.3].
- Impaired Cognitive Function: You may experience confusion, difficulty concentrating, and memory problems [1.2.1].
- Slowed Breathing: In severe cases, the combined CNS depression can lead to dangerously slowed breathing, coma, or even death, though this is rare [1.2.3, 1.4.7].
Increased Anticholinergic Side Effects
Both medications have anticholinergic properties, and combining them increases the 'anticholinergic burden' on the body [1.6.1, 1.6.6]. This can intensify a range of uncomfortable and potentially dangerous side effects, including [1.2.1, 1.3.4, 1.4.5]:
- Severe Dry Mouth
- Blurred Vision
- Constipation
- Urinary Retention (difficulty urinating)
- Heat Intolerance and flushing
- Increased Heart Rate or irregular heartbeat
- Confusion and Hallucinations, especially in the elderly [1.4.4].
Potential for Other Serious Interactions
Beyond sedation and anticholinergic effects, combining these drugs can pose other risks. Hydroxyzine is known to interact with drugs that prolong the QT interval, which can lead to a dangerous abnormal heart rhythm [1.2.6, 1.2.9]. Mixing multiple sedating antihistamines can, in severe instances, increase the risk of cardiac arrest or seizures [1.4.2].
Comparison Table: Hydroxyzine vs. Dramamine
| Feature | Hydroxyzine (Vistaril) | Dramamine (dimenhydrinate) |
|---|---|---|
| Primary Use | Anxiety, Itching, Allergies [1.2.6] | Motion Sickness, Nausea, Vomiting [1.6.8] |
| Drug Class | First-Generation Antihistamine [1.3.3] | First-Generation Antihistamine [1.3.3] |
| Prescription Status | Prescription Only [1.6.9] | Over-the-Counter [1.6.8] |
| Mechanism | H1 receptor antagonist with CNS depressant & anticholinergic effects [1.4.9, 1.6.1] | H1 receptor antagonist with CNS depressant & anticholinergic effects [1.6.8] |
| Common Side Effects | Drowsiness, dry mouth, headache [1.6.1] | Drowsiness, dizziness, dry mouth [1.4.6] |
Safer Alternatives and Precautions
Given the risks, it is best to avoid combining hydroxyzine and Dramamine [1.3.3]. If you are taking hydroxyzine and need relief from motion sickness, consult your doctor or pharmacist. They might recommend:
- Non-Drowsy Antihistamines: Second-generation antihistamines like loratadine (Claritin) or fexofenadine (Allegra) do not readily cross the blood-brain barrier and are less sedating [1.5.2, 1.5.4].
- Non-Pharmacological Options: Acupressure wristbands and ginger supplements are medication-free remedies for motion sickness [1.4.6].
- Timing Doses: A healthcare provider might advise on spacing out medications, but this should only be done under strict medical supervision [1.3.8, 1.4.7].
Always inform your doctor about all medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements, to prevent dangerous interactions [1.2.1].
Conclusion
Combining hydroxyzine with Dramamine is not recommended due to the high risk of additive sedative and anticholinergic side effects [1.2.1]. Both are first-generation antihistamines that depress the central nervous system, and taking them together can lead to excessive drowsiness, confusion, blurred vision, and other serious health issues [1.2.1, 1.2.3]. The risks generally outweigh any potential benefits [1.3.1]. Before mixing any medications, it is essential to seek guidance from a qualified healthcare professional who can assess your individual health status and recommend the safest course of action [1.2.2].
