 Anacin is like a doctor's prescription. That is, anacin contains not just one, but a combination of medically proven active ingredients in easy-to-take tablet form. Thousands of people have received envelopes containing anacin tablets from their own dentist or physician, and in this way discovered the incredibly fast relief anacin brings from pains of headache, neuritis, or neuralgia. So the next time a headache strikes, take anacin for this wonderfully fast relief.
