Hallucinations and possibly delirium resembling the effects of Datura stramonium can result if the drug is taken in much higher than therapeutic doses. Antihistamines are widely available over the counter at drug stores (without a prescription), in the form of allergy medication and some cough medicines. They are sometimes used in combination with other substances such as alcohol. The most common unsupervised use of antihistamines in terms of volume and percentage of the total is perhaps in parallel to the medicinal use of some antihistamines to extend and intensify the effects of opioids and depressants. The most commonly used are hydroxyzine, mainly to extend a supply of other drugs, as in medical use, and the above-mentioned ethanolamine and alkylamine-class first-generation antihistamines, which are – once again as in the 1950s – the subject of medical research into their anti-depressant properties.
