Tenex

Tenex

Other Name: Guanfacine

Category: Antihypertensive

Uses of Tenex:

Tenex belongs to the general class of medicines called antihypertensives. It is used to treat high blood pressure (hypertension) but that may also be helpful in reducing ADHD symptoms. Like another antihypertensive drug, Catapres etc. (Clonidine), Tenex regulates levels of the neurotransmitter norepinephrine and may be effective in reducing ADHD symptoms alone or in combination with stimulants. They also may be used as an alternative to stimulant medication, especially in the 30% of children who cannot tolerate stimulants and in children with conduct problems. However, antihypertensives may not improve attention deficit or distractibility. Tenex may also reduce symptoms of aggression and reduce the insomnia associated with stimulants.

Tenex works by controlling nerve impulses along certain nerve pathways. As a result, it relaxes blood vessels so that blood passes through them more easily. This helps to lower blood pressure.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Tenex for ADHD and Tics disorders like Tourette's syndrome

Tenex is pharmacologically similar to clonidine. In a controlled trial of children with ADHD plus tics like Tourette's syndrome, Tenex improved symptoms in both domains, though the improvements in attention fell short of what is generally seen with standard medications. Side effects are similar to those of clonidine, though Tenex is less sedating.

Research published in the Journal of Psychiatry (July, 2001) concluded that Tenex appears to be a safe and effective treatment for children with tic disorders and ADHD. In the study, Tenex was associated with a mean improvement of 37% in the total score on a teacher-rated ADHD Rating Scale, compared to 8% improvement for placebo after 8 weeks of treatment.

• Check with your doctor before you stop taking guanfacine. Your doctor may want you to reduce gradually the amount you are taking before stopping completely.
• Tenex will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine .
• Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine.
• Make sure that you have enough guanfacine on hand to last through weekends, holidays, and vacations. You should not miss any doses. You may want to ask your doctor for another written prescription for guanfacine to carry in your wallet or purse. You can then have it filled if you run out when you are away from home.
