Withdrawal From Tricyclics

Tricyclic antidepressants commonly produce withdrawal, frequently in the form of cholinergic rebound, with flulike symptoms such as nausea and vomiting, diarrhea, muscle aches, headache, fatigue, and anxiety (Breggin, 1991b). McMahon (1986) summarized  [Pg.419]

Autonomic symptoms are most common and include gastrointestinal disturbance (nausea, diarrhea), general somatic distress (myalgias, malaise, headache, rhinorrhea), sleep disturbances (insomnia, nightmares), and cardiovascular symptoms (arrhythmias, ventricular ectopy). Psychotic decompensation, withdrawal mania, and general anxietylike symptoms have been attributed to abrupt withdrawal of cyclic antidepressants. [Pg.419]

Maxmen and Ward (1995) provided an extensive list of tricyclic antidepressant withdrawal symptoms. One group of withdrawal symptoms includes a flulike syndrome without fever anorexia, nausea, vomiting, diarrhea, queasy stomach, and cramps. A second group involves sleep disturbances insomnia, hypersomnia, excessive dreaming, and nightmares. A third group includes mania and hypomania. Maxmen and Ward pointed out that these symptoms can also be experienced between doses as the blood level drops. [Pg.419]

In my clinical practice, I have seen relatively few cases of very severe, lasting withdrawal reactions from the older antidepressants in comparison to the newer ones, with which serious withdrawal problems are frequent. [Pg.419]

Desipramine has been used to facilitate withdrawal from chronic PCP use. The rationale is that PCP depletes norepinephrine concentrations in brain, and that this tricyclic antidepressant is the most selective blocker of norepinephrine uptake. Consequently, some of the deficiency of the neurotransmitter could be remedied. A dose of 25 to 50 mg was said to reduce craving for several hours. Six of eight patients treated with this drug were successfully withdrawn, while none of the eight offered other types of programs were successful (45). [Pg.145]

Tricyclic antidepressants also have a documented syndrome associated with withdrawal from medications (Petti and Law, 1981). This syndrome can mimic appendicitis or the flu, and can include such symptoms as nausea and vomiting, headache, lethargy, and abdominal pain. If a child on TCAs presents with withdrawal symptoms, questions of compliance must be addressed. [Pg.288]

RBD is characterized by a relative absence of the atonia characteristic of REM sleep. This lack of atonia permits the physical acting out of dream mentation, particularly dreams involving confrontation, aggression and violence. RBD is seen most frequently in older men. RBD occurs in both acute and chronic forms. Acute RBD can occur during withdrawal from alcohol or sedative-hypnotics. RBD has also been induced by the tricyclics, SSRIs and venlafaxine. The chronic form of RBD may occur as part of an identifiable underlying neurological disorder, but typically is idiopathic. RBD may also be an initial manifestation of parkinsonism. RBD is very responsive to clonazepam, although this use has not been FDA approved. [Pg.178]

Among the many toxicants that cause convulsions are chlorinated hydrocarbons, amphetamines, lead, organophosphates, and strychnine. There are several levels of coma, the term used to describe a lowered level of consciousness. At level 0, the subject may be awakened and will respond to questions. At level 1, withdrawal from painful stimuli is observed and all reflexes function. A subject at level 2 does not withdraw from painful stimuli, although most reflexes still function. Levels 3 and 4 are characterized by the absence of reflexes at level 4, respiratory action is depressed and the cardiovascular system fails. Among the many toxicants that cause coma are narcotic analgesics, alcohols, organophosphates, carbamates, lead, hydrocarbons, hydrogen sulfide, benzodiazepines, tricyclic antidepressants, isoniazid, phenothiazines, and opiates. [Pg.154]

The older tricyclic antidepressants and monoamine oxidase inhibitors also cause withdrawal mania and a variety of other adverse withdrawal effects, including cognitive and emotional disturbances and psychosis. Many of them have strong anticholinergic effects and therefore produce severe anticholinergic rebound on withdrawal, including cardiovascular and gastrointestinal symptoms. I have seen patients who have taken tricyclics for many years and then been unable to withdraw from them. [Pg.186]

There is clearly a need for larger controlled studies to determine the incidence and severity of withdrawal effects after withdrawal of tricyclic antidepressants. Based on uncontrolled observations, it has been suggested that the incidence varies from under a quarter to over half of all patients. [Pg.16]

Imipramine (brand name Tofranil) Often referred to as the grandfather of all antidepressants. It is the oldest tricyclic antidepressant available and has traditionally been used for the treatment of depression and for those who have panic attacks. It is sometimes used now to assist with withdrawal from cocaine addiction and in obsessive-compulsive disorder. [Pg.303]

In addition, withdrawal from certain medications, such as baclofen, clonidine, corticosteroids, or tricyclic antidepressants, may cause manic symptoms. [Pg.402]

Other clinical uses Tricyclic drugs are also used in the treatment of bipolar affective disorders, acute panic attacks, phobic disorders (compare with alprazolam Chapter 22), enuresis, and chronic pain states. Clomipramine and the selective serotonin reuptake inhibitors, including fiuvoxamine, are effective in obsessive-compulsive disorders. SSRls are also effective in patients who suffer from panic attacks, social phobias, bulimia, and premenstrual syndrome (PMS) and may also be useful in the treatment of alcohol dependence. Bupropion is used for management of patients attempting to withdraw from nicotine dependence. [Pg.272]

Tricyclics modify peripheral sympathetic effects in two ways through blockade of norepinephrine reuptake at neuroeffector junctions and through alpha adrenoceptor blockade. Sedation and atropine-like side effects are common with tricyclics, especially amitriptyline. In contrast to sedative-hypnotics, tricyclics lower the threshold to seizures. The answer is (B). Selective serotonin reuptake inhibitors cause sexual dysfunction in some patients, with changes in libido, erectile dysfunction, and anorgasmia. Tricyclic antidepressants may also decrease libido or prevent ejaculation. Of the heterocyclic antidepressants bupropion is the least likely to affect sexual performance. The drug is also used in withdrawal from nicotine dependence. The answer is (B). [Pg.277]

A lot of 2- or 2,5-substituted EDOT derivatives can be summarized under the heading "molecular band gap engineering." A wide variety of polymers on EDOT basis with "tuned band gap" and hence modified optical properties have been obtained from tricyclic precursors mentioned earlier (see Eigure 13.24). Copolymerization of EDOT with electron-withdrawing thiophene comonomers was utilized to construct low band gap polymers via electro-oxidation and via Stille coupling (see Figure 13.29). [Pg.313]

In 190 patients taking tricyclic antidepressants that could not be discontinued before surgery, who underwent general and 61 local or regional anesthesia, there were no changes in the cardiovascular effect of halothane, induction time with pentobarbital, propanidid, or ketamine, or the duration of depolarization or recovery time (160). The general conclusion was that it is safer to continue treatment with tricyclic antidepressants than to risk potential disruption from withdrawal before surgery. [Pg.19]

Tricyclic antidepressants reverse the hypotensive effects of postganglionic blocking agents, guanethidine, reser-pine, clonidine, and alpha-methyldopa, and the addition of a tricyclic can result in loss of blood pressure control (159,179). Sudden withdrawal of a tricyclic compound from a patient stabilized with these compounds can also result in serious hypotension. An additional reason for avoiding drugs such as reserpine, methyldopa, and... [Pg.3503]

The tributyltin hydride mediated reaction of a (bromobutyl)cyclohexadienone affords the 6,6-m-annulated bicycle as the sole product32. The exclusive formation of the 6-cxo-product is caused by the rate-accelerating effect of the electron-withdrawing carbonyl group. A similar precursor with an unsubstituted cyclohexadiene gives a tricyclic product derived from 6-endo cyclization as a minor product. [Pg.77]

Opioids (especially methadone and heroin) are the most common cause of serious neonatal drug withdrawal symptoms. Other dmgs for which a withdrawal syndrome has been reported include phencyclidine (POP), cocaine, amphetamines, tricyclic antidepressants, phenothiazines, benzodiazepines, barbiturates, ethanol, clonidine, diphenhydramine, lithium, meprobamate, and theophylline. A careful dmg history from the mother should include illicit drugs, alcohol, and prescription and over-the-counter medications, and whether she is breast-feeding. [Pg.62]
