Antihistamines And Alcohol: Safe To Mix?

Drinking alcohol while taking antihistamines is generally not recommended, as it can lead to negative side effects such as drowsiness, dizziness, impaired coordination, and slowed breathing. First-generation antihistamines like Benadryl are especially dangerous to combine with alcohol due to the increased risk of severe drowsiness and potential for dangerous side effects. While second-generation antihistamines like Claritin and Zyrtec are considered slightly safer, caution is still advised as individual reactions may vary. It is important to talk to your doctor before taking antihistamines to understand your risks and whether it is safe to consume alcohol.

Why you shouldn't drink beer with antihistamines

Antihistamines are commonly used to treat allergy symptoms, such as allergic rhinitis, hay fever, skin rashes, and the common cold. While antihistamines can be effective in providing relief from these symptoms, it is important to be aware of certain precautions, especially when it comes to mixing them with alcohol. Here are several reasons why you shouldn't drink beer with antihistamines:

Increased Risk of Drowsiness:

First-generation antihistamines, such as diphenhydramine (Benadryl), are known to cause drowsiness as a primary side effect. Since alcohol also induces drowsiness, combining the two can lead to extreme sleepiness, impairing your ability to function and increasing the risk of accidents or injuries. This effect may be more pronounced in older adults.

Impaired Brain Communication:

Alcohol interferes with brain communication, initially leading to feelings of happiness and excitement. However, excessive alcohol consumption can result in confusion and lethargy. Mixing alcohol with antihistamines can enhance these negative effects, impacting your coordination, reaction speed, and cognitive abilities.

Dehydration:

Both alcohol and antihistamines can dehydrate the body. When combined, they can increase the risk of dehydration, leading to discomfort and worsening hangover symptoms. Dehydration can also have other negative impacts on your overall health.

Learning and Memory Impairment:

Antihistamines block the action of acetylcholine, a neurotransmitter necessary for learning and memory. Alcohol consumption also inhibits learning and memory functions. Therefore, mixing the two can have a more noticeable detrimental effect on cognitive processes related to learning and memory retention.

Interactions with Other Medications:

Antihistamines may interact with other medications, including prescription drugs, cough and cold medicines, and even other antihistamines. Consuming alcohol while taking antihistamines can heighten these interactions and increase the risk of adverse side effects. It is always important to consult a healthcare professional before mixing medications.

Potential for Misuse:

Antihistamines are sometimes used as sleeping pills, and alcohol is often viewed as a sleep aid. However, mixing the two can disrupt sleep, cause dizziness, and negatively impact your overall well-being. It is important to use antihistamines as directed and avoid combining them with alcohol for purposes beyond their intended use.

In conclusion, while antihistamines can be effective in treating allergy symptoms, it is crucial to avoid drinking beer or consuming any alcohol while taking them. The combination can lead to a range of negative side effects, including drowsiness, impaired coordination, dehydration, cognitive impairment, and potential interactions with other medications. Always consult your healthcare provider for guidance on safely managing your allergies and understanding the risks associated with mixing antihistamines and alcohol.

First-generation antihistamines and alcohol

First-generation antihistamines are the older class of antihistamines known for causing excessive drowsiness. They work by affecting the histamine receptors in the brain and spinal cord. They are also defined by their ability to cross the blood-brain barrier, which can lead to sleepiness.

First-generation antihistamines include:

• Brompheniramine (Children's Dimetapp Cold)
• Clemastine (Dayhist, Tavist)
• Chlorpheniramine (Chlor-Trimeton)
• Cyproheptadine (Periactin)
• Diphenhydramine (Benadryl, Nytol, Sominex)
• Dexchlorpheniramine Dimenhydrinate (Dramamine)
• Doxylamine (Vicks NyQuil, Tylenol Cold and Cough Nighttime)
• Phenindamine (Nolahist)
• Hydroxyzine (Vistaril, Atarax)

When mixed with alcohol, first-generation antihistamines can cause serious side effects. Both alcohol and first-generation antihistamines slow down the central nervous system, which can lead to enhanced drowsiness, dizziness, impaired coordination, and slowed breathing. Older adults are at an increased risk of experiencing these side effects.

It is recommended that individuals avoid alcohol completely when taking first-generation antihistamines. If you are taking a first-generation antihistamine, speak to your doctor about your risks and whether you should stick to non-alcoholic drinks.

Second-generation antihistamines and alcohol

Second-generation antihistamines are generally considered safer than first-generation antihistamines because they do not cause sleepiness and interact better with other medications. Examples of second-generation antihistamines include desloratadine (Clarinex), fexofenadine (Allegra), and loratadine (Claritin). While second-generation antihistamines are less likely to produce sedation, they can still cause drowsiness, especially when combined with alcohol.

Alcohol can slow down your central nervous system (CNS), making you feel drowsy, impairing your coordination, and slowing down your breathing. When combined with antihistamines, these effects can be enhanced. Therefore, it is generally recommended to avoid or limit alcohol consumption when taking second-generation antihistamines.

However, the effects of alcohol and antihistamines can vary between individuals. Some people might tolerate one to two drinks while taking second-generation antihistamines, as alcohol tolerance can vary with age and sex. It is always a good idea to talk to your doctor before taking any medication, including antihistamines, to understand your risks and potential side effects.

If you are concerned about the effects of alcohol and antihistamines, there are alternative treatment options for allergies. Nasal corticosteroids, such as Nasonex or Flonase, can provide congestion relief without causing drowsiness. However, they only provide local relief for symptoms like a stuffy nose and irritation. Always consult a healthcare professional to determine the most suitable treatment option for your specific situation.

Side effects of mixing antihistamines and alcohol

Mixing antihistamines and alcohol can cause several side effects, and it's generally not recommended. The specific side effects will depend on the type of antihistamine you're taking, as well as your age, size, health conditions, and other medications you may be taking. Here are some of the possible side effects:

First-Generation Antihistamines (H-1 Blockers)

First-generation antihistamines are known for causing excessive drowsiness, and mixing them with alcohol can lead to extreme drowsiness, impaired coordination and judgment, and increased risk of injury or accident. Older adults are at a higher risk of experiencing these side effects. Examples of first-generation antihistamines include:

• Diphenhydramine (Benadryl)
• Brompheniramine (Children's Dimetapp Cold)
• Chlorpheniramine (Chlor-Trimeton)
• Clemastine (Dayhist, Tavist)
• Cyproheptadine (Periactin)
• Dexchlorpheniramine (Polaramine)
• Dimenhydrinate (Dramamine)
• Doxylamine (Tylenol Cold and Cough Nighttime, Vicks NyQuil)
• Phenindamine (Nolahist)
• Hydroxyzine (Vistaril, Atarax)

Second-Generation Antihistamines (Non-Drowsy)

While second-generation antihistamines are less likely to cause drowsiness, consuming alcohol with them can still enhance this side effect. Examples of second-generation antihistamines include:

• Cetirizine (Zyrtec)
• Loratadine (Claritin)
• Fexofenadine (Allegra)
• Azelastine (Astelin)
• Desloratadine (Clarinex)

Other Side Effects

In addition to drowsiness, mixing antihistamines and alcohol can potentially lead to more serious complications, especially in the case of an overdose. Signs of an antihistamine overdose may include increased drowsiness, increased heart rate, fever, dilated pupils, low blood pressure, and urinary retention. In severe cases, an overdose can lead to respiratory distress, cardiac arrest, seizures, or even death.

Alternatives to antihistamines

While antihistamines are a common way to treat allergies, they can cause side effects such as drowsiness and nausea. As a result, some people opt for natural alternatives. Here are some alternatives to antihistamines:

Stinging Nettle

Stinging nettle (Urtica dioica) is a centuries-old herbal medication used to treat various conditions. Some naturopathic practitioners believe it has antihistamine effects. However, evidence supporting its use for allergies is limited. Stinging nettle is available in teas, tinctures, or supplements. Possible side effects include an upset stomach, fluid retention, sweating, and diarrhea.

Vitamin C

Vitamin C has potent anti-inflammatory and antioxidant effects, which can help alleviate inflammation-induced allergy symptoms. A 2018 study found that high doses of intravenous vitamin C improved allergy symptoms in adults with skin and respiratory allergies. Citrus fruits and juices, tomatoes and tomato juice are good sources of vitamin C. However, taking more than 2,000 milligrams per day is not advised due to potential side effects.

Quercetin

Quercetin is an antioxidant flavonoid found in many plants and foods. Research suggests it has anti-allergic and antihistamine properties. It may block the pathways that trigger the release of histamine into the bloodstream. Quercetin is available as a nutritional supplement and is found in foods such as apples, berries, red grapes, red onions, black tea, cranberries, and blueberries. Side effects may include headaches or an upset stomach.

Ceylon Cinnamon

Ceylon cinnamon, derived from the bark of the Cinnamomum zeylanicum tree, has been used in traditional medicine to treat cold symptoms and allergic reactions. Its active ingredient, cinnamaldehyde, has anti-inflammatory properties that may reduce inflammatory responses related to allergens. Ceylon cinnamon can be used to create tea or added to other beverages and dishes.

Butterbur

Butterbur (Petasites hybridus) is a shrub native to Europe, Asia, and North America. It has been used since the Middle Ages to treat various conditions, including allergic rhinitis and hay fever. Butterbur extract may provide significant and sustained relief from seasonal allergy symptoms for up to eight weeks. However, it is unclear if butterbur works as a standalone antihistamine or in conjunction with other treatments. Butterbur is sold in supplement, extract, or dried forms. Side effects may include belching, headaches, itchy eyes, diarrhea, and breathing problems. People with allergies to ragweed, chrysanthemums, marigolds, or daisies should avoid butterbur.

Nasal Corticosteroids

Nasal corticosteroids, such as Nasonex or Flonase, are an alternative treatment option for seasonal allergies. They relieve congestion without causing drowsiness. However, they only provide local relief for symptoms like a stuffy nose and irritation. A healthcare professional can advise if nasal corticosteroids are suitable for you.
