Tenex vs Adderall
Introduction
For patients with attention deficit hyperactivity disorder (ADHD) or related disorders, certain drugs that alter the concentrations of compounds in the brain linked to focus and impulse control can help in managing symptoms. Tenex and Adderall are two such drugs often prescribed for ADHD. They each impact different neurotransmitters in the brain but both have effects on patients' ability to concentrate and control impulses. Tenex, also known as Guanfacine, is classified as a selective alpha-2A adrenergic receptor agonist which primarily affects norepinephrine levels by stimulating receptors in the prefrontal cortex - an area associated with attention, impulse regulation, and executive function. On the other hand, Adderall is an amphetamine type stimulant affecting levels of both dopamine and norepinephrine by increasing their release into the synaptic cleft where neurons communicate.

What is Tenex?
Guanfacine (the generic name for Tenex) is a non-stimulant medication first approved by the FDA in 1986. It's often used to treat high blood pressure but has also been found effective in treating Attention Deficit Hyperactivity Disorder (ADHD), particularly when stimulant medications are not preferred or have caused adverse side effects. Guanfacine works by stimulating receptors in the brain that reduce nerve signal transmission, thus helping to decrease distractibility and impulsivity.
On the other hand, Adderall is a well-known stimulant medication primarily prescribed for ADHD treatment. Originally approved by the FDA in 1996, it works differently from Tenex; rather than reducing nerve signal transmission, Adderall increases levels of dopamine and norepinephrine neurotransmitters within the brain. This increased activity can improve focus, attention span, and behavioral control.
While both drugs serve as treatment options for ADHD, they work via different mechanisms and may produce differing side effects. For instance, while both can potentially cause dizziness or dry mouth among other side effects, Adderall might increase heart rate more significantly due to its stimulant properties.
What conditions is Tenex approved to treat?
Tenex (guanfacine) and Adderall are both approved for distinct medical conditions:
- Tenex is primarily used to treat high blood pressure (hypertension), but it's also used off-label for attention deficit hyperactivity disorder (ADHD)
- Adderall, on the other hand, is specifically approved to treat ADHD and narcolepsy.
How does Tenex help with these illnesses?
Tenex, also known as guanfacine, helps manage symptoms of ADHD by increasing the amount of norepinephrine available in the synapses of the brain. It does this by stimulating receptors that inhibit norepinephrine release, which paradoxically results in overall increased levels. Norepinephrine is a neurotransmitter, a chemical messenger in the brain and throughout the body, involved in attention and response actions amongst other things. In those with ADHD, there may be relatively lower levels or an inefficient use of norepinephrine. Therefore, by increasing its availability through stimulation of these inhibitory receptors, Tenex can help limit negative effects associated with ADHD such as impulsivity and improve patients' ability to focus.
On another hand, Adderall works on both dopamine and norepinephrine neurotransmitters not just one like Tenex. This different mechanism makes Adderall generally more potent but potentially comes with more side effects compared to Tenex.
What is Adderall?
Adderall is a brand name for a combination of amphetamine and dextroamphetamine, central nervous system stimulants that affect chemicals in the brain and nerves contributing to hyperactivity and impulse control. It is primarily used as part of a treatment plan for attention deficit hyperactivity disorder (ADHD). The drug was first approved by the FDA in 1996.
As Adderall is not an alpha-2 adrenergic receptor agonist like Tenex, it does not work by relaxing blood vessels or decreasing heart rate. Instead, its action on stimulating the release of norepinephrine from presynaptic neurons results in enhanced cognitive function, including increased concentration and decreased impulsivity. Its lack of action on alpha-2 receptors means its side-effect profile also differs from that of drugs like Tenex; instead, common side effects can include insomnia, dry mouth, loss of appetite and mood swings. The benefits on focus and attentiveness can make Adderall particularly beneficial for those struggling with ADHD symptoms unresponsive to other medications such as Tenex.
What conditions is Adderall approved to treat?
Adderall is a medication that has been approved by the FDA for treating a range of conditions, including:
- Attention Deficit Hyperactivity Disorder (ADHD)
- Narcolepsy, which is characterized by excessive daytime sleepiness or sudden attacks of deep sleep.
How does Adderall help with these illnesses?
Adderall is a central nervous system stimulant that works by increasing the levels of norepinephrine and dopamine in the brain, thereby improving focus, attention, and reducing impulsivity and hyperactivity in patients with ADHD. This makes it an effective treatment for individuals struggling with this condition. Its impact on these neurotransmitters can also increase wakefulness, which may be beneficial for those dealing with narcolepsy. While Tenex can be used to manage symptoms of ADHD as well, it primarily lowers blood pressure by relaxing the blood vessels. Unlike Adderall, Tenex does not significantly affect dopamine or norepinephrine levels in the brain which means it doesn't have stimulatory effects or addiction potential like Adderall does.
How effective are both Tenex and Adderall?
Both guanfacine (Tenex) and amphetamine-dextroamphetamine (Adderall) have established roles in the treatment of Attention Deficit Hyperactivity Disorder (ADHD), though they were approved by the FDA several years apart, with Adderall gaining approval first. These medications function differently in addressing ADHD symptoms, hence they might be prescribed under different circumstances.
Guanfacine is an alpha-2A adrenergic receptor agonist that acts on the prefrontal cortex to improve attention span and reduce impulsivity; a 2001 double-blind clinical trial directly compared its efficacy against placebo for treating children with ADHD, finding it to provide significant symptom improvement. A later meta-analysis conducted in 2016 confirmed these findings and suggested that guanfacine may be particularly beneficial for patients who experience side effects from stimulant medication like Adderall or those who do not respond adequately to such treatments.
On the other hand, amphetamine-dextroamphetamine works primarily by increasing levels of dopamine and norepinephrine in the brain thus improving focus while reducing hyperactivity and impulsive behavior. This dual action makes it highly effective at managing ADHD symptoms as evidenced by numerous studies over many years since its initial development as a therapeutic agent for this disorder.
In summary, both Tenex and Adderall are effective options for treating ADHD each having unique features dictated by their distinct mechanisms of action which influence their prescription based on individual patient needs.

At what dose is Tenex typically prescribed?
Oral dosages of Tenex, also known as guanfacine, usually start at 0.5-1 mg/day for treating high blood pressure or ADHD in adults and children over the age of 12. However, this can be increased after a few weeks if there is no response, up to a maximum of 3 mg/day. For children aged between 6 and 12 years old with ADHD, the starting dose is typically lower at about 0.5 mg/day but can again be adjusted upwards as necessary by their healthcare provider. The maximum dosage that should not be exceeded in any case is 4 mg/day.
At what dose is Adderall typically prescribed?
Adderall therapy typically starts with a dosage of 5 mg once or twice a day. The dose can be gradually increased at weekly intervals by 5 mg per day, as needed and tolerated. Most patients find that their optimal dosage is between 20-30 mg/day, divided into two doses, spaced about 4 to 6 hours apart. However, in some cases where there is no response to initial treatment or for severe symptoms, the maximum dose could go up to 40 mg/day divided into two doses and spaced approximately 4-6 hours apart after consultation with your healthcare provider.

Contraindications for Tenex and Adderall?
Both Tenex and Adderall, like most central nervous system stimulants and alpha-2 adrenergic agonists, can exacerbate symptoms of anxiety or other psychiatric disorders. If you notice worsening anxiety or any changes in behavior such as agitation, hallucinations, paranoia or suicidal ideation while using these medications, seek immediate medical attention.
Neither Tenex nor Adderall should be used if you have taken monoamine oxidase (MAO) inhibitors within the past two weeks. Always inform your doctor about all the medications you're taking; MAOIs will require a period of approximately 2 weeks to clear from your system to prevent potentially dangerous interactions with both Tenex and Adderall.
How much do Tenex and Adderall cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Tenex (1 mg) averages around $80, which works out to roughly $2.67 per day if taking two tablets daily.
- The price of 30 capsules of Adderall XR (20 mg) is approximately $220, working out to about $7/day.
Thus, if you are on a higher dosage for Adderall i.e., 40 mg/day or higher, then brand-name Tenex would be less expensive on a per-day treatment basis. Please note that cost should not be your primary consideration when determining which medication might work best for you.
Regarding the generic versions:
-
Guanfacine (generic version of Tenex) costs between $0.50 and $1 per tablet depending upon the strength chosen and quantity bought at one time; this translates into an approximate daily cost range from as low as less than half a dollar up to two dollars based on typical doses.
-
Amphetamine salts ER (the generic form equivalent to Adderall XR), depending upon dose and pack size purchased together with possible insurance coverage applied, may come in quite variable pricing but could average somewhere between just over one dollar up toward five dollars each day given common dosing schedules.
Popularity of Tenex and Adderall
Guanfacine, available in generic form as well as under brand names such as Tenex, was prescribed to approximately 2 million people in the US in 2020. Guanfacine accounts for a significant portion of non-stimulant ADHD medication prescriptions. Although it's less commonly known than stimulant medications like Adderall or Ritalin, its use has been increasing over the last decade due to its effectiveness and lower risk of abuse.
On the other hand, mixed amphetamine salts including brand versions such as Adderall were prescribed to nearly 16 million people in USA during 2020. In America, Adderall represents a large percentage of overall stimulant prescriptions for ADHD treatment and is one of the most recognized treatments for this condition. The prevalence of Adderall usage has shown an upward trend over recent years due to increased awareness and diagnosis rates of ADHD.
Conclusion
Both Tenex (guanfacine) and Adderall (amphetamine and dextroamphetamine) have established usage in managing attention-deficit hyperactivity disorder (ADHD), with numerous clinical studies supporting their efficacy over placebo treatments. In some cases, these drugs may be used together, but this requires careful consideration by a healthcare professional due to potential drug interactions. Their mechanisms of action differ: Tenex works primarily on alpha-2 adrenergic receptors to help reduce nerve signal transmission linked with impulse control and attention, while Adderall acts mainly on the release of dopamine and norepinephrine for improved concentration.
Adderall is often considered as a first-line treatment option in ADHD management owing to its robust evidence base, whereas Tenex might typically be added as an adjunct therapy or prescribed for patients who don't respond well to stimulant medications or need to avoid common side effects associated with them such as appetite suppression or insomnia.
Both drugs are available in generic forms which can lead to significant cost savings especially for patients paying out-of-pocket. Both medications may require an adjustment period where benefits aren't immediately noticeable.
Side effect profiles are relatively similar between the two drugs; however, they're generally well-tolerated. Notably though, unlike Adderall's tendency towards side effects like increased heart rate and blood pressure, Tenex can cause low blood pressure and slow heart rate instead. For both medications, it's essential that individuals closely monitor their response particularly when starting treatment and promptly seek medical assistance if adverse reactions occur or symptoms worsen.
