Anxiety Treatment

Medication Interactions and Safety

Hydroxyzine and buspirone can be safely used together for anxiety treatment, as they work through different mechanisms and have no significant contraindicated interactions, according to the American Academy of Pediatrics 1
The combination of hydroxyzine and buspirone does not carry a significant risk of serotonin syndrome, as stated by the American Academy of Child and Adolescent Psychiatry 2
Hydroxyzine is listed as a QT-prolonging medication, but buspirone does not have this effect, with moderate strength of evidence 1
Hydroxyzine pamoate should be used with caution in elderly patients due to increased risk of cognitive decline, falls, and anticholinergic effects, and in children, as it may impair learning and school performance, as advised by the American Geriatrics Society and the American Academy of Pediatrics 3, 4
Hydroxyzine pamoate is contraindicated during early pregnancy and should be used with caution in patients with renal or liver impairment, as recommended by the National Kidney Foundation, the American Association for the Study of Liver Diseases, and the FDA 3, 5

SSRIs or SNRIs may be preferred first-line options for long-term anxiety management, as recommended by the American Academy of Child and Adolescent Psychiatry 2
Buspirone may be a safer alternative for anxiety treatment, as recommended by the National Institute of Mental Health 6
For insomnia, short-acting benzodiazepine receptor agonists or ramelteon may be preferred, especially for those with substance use concerns, according to the American Academy of Sleep Medicine 6

Hydroxyzine is a suitable next-line antihistamine treatment for patients with persistent itching, or alternatively, topical hydrocortisone can be applied to affected areas up to 3-4 times daily, according to the British Journal of Dermatology guidelines 7
Non-sedating H1 antihistamine options include cetirizine 10mg, loratadine 10mg, or fexofenadine 180mg, which may be preferable for daytime use to avoid excessive sedation 7
H2 antagonists, such as famotidine or cimetidine, can be added to H1 antagonists for a synergistic effect, and the combination may be more effective than either alone 7
Menthol-containing preparations provide a cooling sensation that can help relieve itching 7
Consider nalbuphine or carefully titrated naloxone if pruritus is clearly opioid-related, as recommended by the National Comprehensive Cancer Network 8, 9
Ondansetron may be particularly helpful for opioid-induced pruritus 8, 9
Gabapentin may be considered for pruritus treatment, but should be avoided in hepatic pruritus 7
Broadband UVB phototherapy is effective for many patients 7
Rifampicin is first-line treatment for certain cases of pruritus 7

Monitor for anticholinergic effects, which are especially problematic in elderly patients, as advised by the American Geriatrics Society 3
Liver function tests should be monitored before and during antihistamine treatment in patients with liver disease, with careful consideration of the risk of hepatic encephalopathy and worsening liver function, as recommended by the American Association for the Study of Liver Diseases 10
When performing oral food challenges or allergy testing, hydroxyzine should be discontinued 7-10 days before the procedure, as recommended by the Journal of Allergy and Clinical Immunology 11
The American Academy of Allergy, Asthma, and Immunology recommends avoiding first-generation antihistamines due to their extensive hepatic metabolism and considering second-generation antihistamines at reduced doses, typically half the standard dose, for patients with liver disease 3, 10
