Pharmacist Warns of Risks Mixing Hay Fever Medication with Alcohol and Other Drugs

A leading pharmacist has cautioned hay fever sufferers about the potential risks of combining their allergy medication with other substances, including alcohol and certain medications. Peter Thnoia, a superintendent pharmacist, emphasized the importance of understanding the ingredients in antihistamines, as some can induce drowsiness, which can be intensified when mixed with other substances.

The Met Office has predicted elevated pollen levels across the UK, with particularly high levels expected in the East Midlands. Mr. Thnoia noted that many individuals consume alcohol while taking hay fever medication, potentially unaware of the possible adverse effects. He explained that alcohol significantly increases the sedative effects of first-generation hay fever tablets, which can lead to severe impairment, unconsciousness, or serious accidents. Even non-drowsy antihistamines can sometimes react with alcohol, depending on individual sensitivity, making it advisable to avoid alcohol altogether when taking allergy medication.

Furthermore, taking certain hay fever medications alongside sleeping tablets or tranquilizers, such as diazepam or zopiclone, can heighten the risk of breathing difficulties. First-generation antihistamines are particularly known for causing drowsiness and can become dangerous when combined with other sedatives. Mr. Thnoia stressed that taking sedating-style tablets is not recommended if already taking medication to aid sleep, as this combination can impact breathing, cause shortness of breath, dizziness, and in extreme cases, lead to unconsciousness.

Certain antidepressants, specifically tricyclic antidepressants (TCAs), can also have similar sedative effects when combined with hay fever medication. Mr. Thnoia also highlighted that even some of the most commonly prescribed antidepressants, such as SSRIs, can react negatively when combined with allergy medications. He recommended opting for non-drowsy antihistamines, such as loratadine, cetirizine, and fexofenadine, if taking them alongside sleep aids or tranquilizers. Individuals concerned about the potential interactions of their medications should consult with a healthcare professional.
