Sleep & Stress

Short-term sleep aids and stress-support products. Most clinically-effective sleep aids contain a sedating antihistamine — these are pharmacy-only because they're not for long-term use. If sleep is persistently disrupted, we'd rather have a conversation than send you home with tablets.

When to talk to the pharmacist before buying

Sleep aids are for short-term use only — typically up to 7 nights. If you've been struggling with sleep for weeks or months, tablets aren't the right answer — let's talk about what's driving it.
You're over 65 — sedating antihistamines like diphenhydramine and promethazine can cause confusion and falls in older adults. We can suggest safer alternatives.
You drive or operate machinery — these medicines cause next-day drowsiness; not safe alongside driving.
You're already on antidepressants, anti-anxiety medicines, or strong painkillers — sedating effects can stack.
You're pregnant, breastfeeding, or have asthma, glaucoma, or prostate problems — many sleep aids are not recommended; ask first.
Anxiety that's affecting your daily life — your GP can offer talking therapies and other support. We can signpost.

Walk in, phone 0113 244 1551, or message WhatsApp.

Mental-health support: if you're struggling, Samaritans (116 123, free, 24/7) and NHS 111 (option 2 for mental health) are there. We can also point you to local Leeds NHS talking-therapy services.
