Caffeine, memory, and OTC medication safety: what old links were pointing to

A high-authority cluster of old links points to a 1999 PlanetRx news item titled around caffeine and brain cells. Rather than republishing an old news item as current health guidance, this page explains the historical link and points readers to modern, source-backed OTC safety basics.

Caffeine is widely used in beverages and some OTC products. The practical safety question is usually total daily intake, interactions with other stimulants, sleep disruption, anxiety, blood pressure, and medication-specific warnings.

Read the Drug Facts label, check total caffeine from all sources, avoid combining multiple stimulant products, and ask a pharmacist if you take heart, blood-pressure, ADHD, anxiety, sleep, or migraine medications.

PlanetRx does not provide medical advice. If caffeine causes palpitations, severe anxiety, chest pain, or other concerning symptoms, seek medical care.
