Phenobarbital is a barbiturate medication primarily used as an anticonvulsant to control seizures and as a sedative to treat anxiety and insomnia. It works by depressing the central nervous system, leading to sedation and a reduction in neuronal excitability. Phenobarbital is often prescribed for conditions like epilepsy and is sometimes used in the management of withdrawal symptoms from alcohol or other sedatives. Due to its potential for dependence and side effects, its use is generally more restricted compared to newer anticonvulsants.
Phenobarbital is a barbiturate with mild sedative and hypnotic qualities used mostly for the treatment of siezures.
The cost of 2 grams of phenobarbital can vary depending on the brand, location, and prescription coverage. It's best to check with your local pharmacy for accurate pricing.
It is very unlikely for one drug to cause a false positive on a drug screen for any other substance. Drug screens test for metabolites of specific drugs. All drug tests have a rating based on specificity and sensitivity. The higher the sensitivity, the lower the specificity. Basically it is only possible to have a false positive by using another drug that is very chemically similar to the positive test.
