==Special Precautions of Caffeine==
* Caffeine is LIKELY SAFE for most adults when used appropriately. Caffeine can cause insomnia, nervousness and restlessness, stomach irritation, nausea and vomiting, increased heart rate and respiration, and other side effects. Caffeine can make sleep disorders in patients with acquired immunodeficiency syndrome (AIDS) worse. Larger doses might cause headache, anxiety, agitation, chest pain, and ringing in the ears.* Headache : caffeine does not directly cause headache, too much of the substance can trigger “caffeine rebound.” A caffeine rebound headache occurs from withdrawals of caffeine after a sufferer continually consumes too much of it. Though the physical side effects can be severe, only 2% of the population suffers from caffeine rebound.
* Large doses may be UNSAFE and can cause irregular heartbeats and even death.
*Pregnancy and breast-feeding: Caffeine is POSSIBLY SAFE in pregnant or breast-feeding women in daily amounts of less than 200 mg. This is about the amount in 1-2 cups of coffee. Consuming larger amounts during pregnancy might increase the chance of miscarriage and other problems. Caffeine passes into breast milk, so nursing mothers should closely monitor caffeine intake to make sure it is on the low side. Caffeine in large amounts is POSSIBLY UNSAFE during breast-feeding. Caffeine can cause sleep disturbances, irritability, and increased bowel activity in breast-fed infants.
*High blood pressure: Consuming caffeine might increase blood pressure in people with high blood pressure. However, this effect might be less in people who use caffeine regularly.
*Weak bones (osteoporosis): Caffeine can increase the amount of calcium that is flushed out in the urine. If you have osteoporosis or low bone density, caffeine should be limited to less than 300 mg per day (approximately 2-3 cups of coffee). It’s also a good idea to get extra calcium to make up for the amount that may be lost in the urine. Older women with an inherited disorder that affects the way vitamin D is used should use caffeine with caution. Vitamin D works with calcium to build bones.
* Caffeine Linked to vasomotor symptoms of menopause (Hot Flashes and Night Sweats)
* Ephedrine interacts with CAFFEINE
