What is Tuinal?

Tuinal also known as Pentobarbital, is a barbiturate used in the short-term treatment of insomnia. Tuinal slows the activity of your brain and nervous system allowing use as a sedative to relieve anxiety and induce sleep before a surgical procedure.

Barbiturates such as Tuinal may be habit forming. Tolerance, psychological and physical dependence may occur following prolonged use of high doses of Barbiturates. Symptoms of acute intoxication with Barbiturates may include unsteady gait, sustained nystagmus, and slurred speech. Mental signs of chronic intoxication include poor judgment, confusion, irritability, insomnia, and somatic complaints.

Symptoms of Barbiturate dependence are similar to those of chronic alcoholism. Individuals appear to be intoxicated with alcohol to a degree that is radically disproportionate to the amount of alcohol in their blood.

Symptoms of Barbiturate withdrawal can be severe and may cause death. Minor withdrawal symptoms may appear 8 to 12 hours after the last dose. These symptoms generally appear in the following order: anxiety, muscle twitching, tremor of hands and fingers, progressive weakness, dizziness, distortion in visual perception, nausea, vomiting, insomnia, and orthostatic hypotension. Major withdrawal symptoms can occur within 16 hours and last up to 5 days after abrupt cessation in usage.

Intensity of withdrawal symptoms gradually decline over a period of approximately 15 days without use.
