Who Makes Xanax: Is This a Product of Pfizer

Xanax is a medication prescribed to treat anxiety disorders and panic attacks. It is a Benzodiazepine, which means it belongs to a class of drugs that act as central nervous system depressants. But, who makes this drug?

Who Makes Xanax?

Today, Xanax is one of the most commonly prescribed psychiatric medications in the United States. But who makes Xanax? The answer may surprise you. While the drug is now manufactured by Pfizer, a leading pharmaceutical company, it was actually originally created by a small Swedish company called Pharmacia. In the early 1990s, Pharmacia began marketing the drug as a treatment for panic disorder, and it quickly became one of the most popular psychiatric medications on the market.

However, in 1995, Pharmacia was acquired by Upjohn Co., a large American pharmaceutical company. Upjohn was then acquired by Pfizer in 2002, and Pfizer has been manufacturing and marketing Xanax ever since. So while it may seem like Xanax has always been made by Pfizer, that is actually not the case. The drug has a long and interesting history, and it is now one of the most commonly prescribed medications in the world.

What Should You Not Do Before Taking Xanax?

Xanax is a prescription sedative or hypnotic used for the treatment of anxiety and panic disorders. It should only be taken as prescribed by a doctor. Some of the things you should avoid doing before taking Xanax include operating machinery, driving, or performing tasks that require mental alertness. You should also avoid alcohol while taking this medicine. 

The lowest effective dose of Xanax should be used for the shortest time possible. If you have any questions about what you should or should not do before taking Xanax, be sure to ask your doctor or pharmacist.

How Long Does Xanax Work in a Day?

The answer depends on a few factors, including the individual’s metabolism and the severity of symptoms. On average, Xanax has a half-life of around 12 hours, which means that it is no longer effective after 4 hours. For this reason, people who use Xanax may need to take it several times per day. The exact schedule will depend on the prescription and the individual’s response to the drug. 


In some cases, people may only need to take Xanax once or twice per day, while others may need to take it several times. If you are using Xanax, be sure to follow your doctor’s instructions carefully to ensure that you are taking it as directed.

Why Do You Lose Memory on Xanax?

GABA [1] is a neurotransmitter that plays a role in inhibiting excessive neuronal activity. It’s present throughout the entire brain and spinal cord. When it’s working properly, GABA helps regulate anxiety levels, mood, epileptic seizures, and sleep cycles. Drugs like Xanax and alcohol increase the effects of GABA. This is done by binding to the same receptors that GABA does. 

This action makes it so there’s less communication between neurons, which has a sedative and calming effect. In high enough doses, this can lead to anesthesia or even coma. That’s why it’s important not to drink alcohol while taking Xanax or any other benzo. Mixing the two can lead to dangerous levels of impairment and put you at risk for accidents and injuries. 

As for why you lose memory on Xanax specifically, it’s because the drug causes such a strong sedative effect that it can cause blackouts. During a blackout, you may be able to function but won’t remember what happened afterward. This is similar to what happens when people drink too much alcohol and experience a “beer goggles” type of effect.

Basically, your judgment and decision-making skills are impaired, which can lead to risky behavior. So if you’re planning on taking Xanax, make sure you don’t drink alcohol and have someone with you who can keep an eye on you.

What is the Strongest Xanax?

Alprazolam, better known by its brand name Xanax, is a powerful benzodiazepine medication primarily used to treat anxiety and panic disorders. Benzodiazepines work by enhancing the activity of the neurotransmitter GABA in the brain, leading to a calming effect. Xanax comes in a variety of strengths. The highest strength dose is a 3-mg extended-release tablet, which is triangular and green. 

Because of the wide range of strengths and manufacturers, it’s important to only take Xanax if it has been specifically prescribed to you and came from its original prescription pill bottle. Taking a higher strength than prescribed or taking someone else’s Xanax can be dangerous and lead to serious side effects or even overdose. 


Xanax is a powerful medication that should only be taken as prescribed by a doctor. If you or someone you know is struggling with an addiction to Xanax, please reach out for help. There are many resources available to get you on the road to recovery.
