Prior to starting treatment with opioids, a discussion should be held with patients to put in place a strategy for ending treatment with methadone in order to minimise the risk of addiction and drug withdrawal syndrome see section 4.

The decision to maintain a patient on a long-term opioid prescription should be an active decision agreed between the clinician and patient with review at regular intervals usually at least three-monthly, depending on clinical progress. Initially 10 - 20mg per day, increasing by 10 - 20mg daily until there is no of withdrawal or intoxication.

The usual dose is mg per day. Dosage in pregnancy: Drug withdrawal needs to be achieved weeks Green methadone pill delivery if neonatal abstinence syndrome is to be certain to be avoided, but abrupt withdrawal can cause intrauterine death. Detoxification to abstinence is least stressful to mother and foetus if undertaken during the mid-trimester. Abstinence syndrome may not occur Green methadone pill the neonate for some days after birth.

In the event that withdrawal is not possible prior to delivery, methadone administered to the mother may result in prolonged respiratory depression in the neonate and the administration of opiod antagonists may be required. In the case of elderly or ill patients, repeated doses should only be given with extreme caution. Methadone is a drug of addiction and is controlled under the. Misuse of Drugs Act Schedule 2. Methadone has a long half-life and can therefore accumulate. A single dose which will relieve symptoms may, if repeated on a daily basis, lead to accumulation and possibly death.

Prolonged use of this product may lead to drug dependence addictioneven at therapeutic doses. The risks are increased in individuals with current or past history of substance misuse disorder including alcohol misuse or mental health disorder e. It is important that patients only use medicines that are prescribed for them at the dose they have been prescribed Green methadone pill do not give this medicine to anyone else.

Patients should be closely Green methadone pill for s of misuse, abuse, or addiction. The clinical need for continuing opioid substitution therapy should be reviewed regularly. Tolerance and dependence of the morphine type may occur. Methadone should be given with caution to patients with history of asthma see section 4. In cases of hepatic or renal impairment the use of methadone should be avoided or given in reduced doses. Methadone can produce drowsiness and reduce consciousness although tolerance to these effects can occur after repeated use.

Methadone should be administered with caution to patients at risk for development of prolonged QT interval, e. In patients with recognised risk factors for QT prolongation, or in case of concomitant treatment with drugs that have a potential for QT-prolongation, ECG monitoring is recommended prior to methadone treatment, with a further ECG test at dose stabilisation. Methadone, as with other opiates, has the potential to increase intracranial pressure especially where it is already raised. Prior to starting treatment with any opioids, a discussion should be held with patients to put in place a withdrawal strategy for ending treatment with methadone.

Drug withdrawal syndrome may occur upon abrupt cessation of therapy or dose reduction.

When a patient no longer requires therapy, it is advisable to taper the dose gradually to minimise symptoms of withdrawal. The opioid drug withdrawal syndrome is characterised by some or all of the following: restlessness, lacrimation, rhinorrhoea, yawning, perspiration, chills, myalgia, mydriasis and palpitations.

Other symptoms may also develop including irritability, agitation, anxiety, hyperkinesia, tremor, weakness, insomnia, anorexia, abdominal cramps, nausea, vomiting, diarrhoea, increased blood pressure, increased respiratory rate or heart rate. If women take this drug during pregnancy, there is a risk that their new-born infants will experience neonatal withdrawal syndrome. Opioid analgesics may cause reversible adrenal insufficiency requiring monitoring and glucocorticoid replacement therapy. Symptoms of adrenal insufficiency may include nausea, vomiting, loss of appetite, fatigue, weakness, dizziness, or low blood pressure.

Long-term use of opioid analgesics may be associated with decreased sex hormone levels and increased prolactin. Symptoms include decreased libido, impotence or amenorrhea. Hypoglycaemia has been observed in the context of methadone overdose or dose escalation. Regular monitoring of blood sugar is recommended during dose escalation see section 4. Caution as methadone may precipitate porto--systemic encephalopathy in patients with severe liver damage.

As with other opioids, methadone may cause troublesome constipation, which is particularly dangerous in patients with severe hepatic impairment, and measures to avoid constipation should be initiated early. Risk from concomitant use of sedative medicines such as benzodiazepines or related drugs :. Because of these risks, concomitant prescribing with these Green methadone pill medicines should be reserved for patients for whom alternative treatment options are not possible.

The patients should be followed closely for s and symptoms of respiratory depression and sedation. In this respect, it Green methadone pill strongly recommended to inform patients and their caregivers to be aware of these Green methadone pill see section 4. As there is a risk of greater respiratory depression in neonates and because there are currently insufficient published data on the use in children, methadone is Green methadone pill recommended in those under 16 See sections 4.

Due to the slow accumulation of methadone in the tissues, respiratory depression may not be fully apparent for a week or two and may exacerbate asthma due to histamine release. Concomitant treatment with other agents with CNS depressant activity is not advised due to the potential for CNS and respiratory depression see also section 4.

Contains Liquid Maltitol E Patients with rare Green methadone pill problems of fructose intolerance should not take this medicine. Alcohol, anaesthetics, hypnotics and sedatives, barbiturates, phenothiazines, some other major tranquillizers and tricyclic antidepressants may increase the general depressant effects of methadone when used concomintantly. See 4. There are reports that antidepressant drugs e. Histamine H2 antagonists such as cimetidine, can reduce the protein binding of methadone resulting in increased opiate action. Reduced plasma levels and increased urinary excretion of methadone can occur with concurrent administration of rifampicin.

Adjustment of the dose of methadone may be necessary. Induces the metabolism of methadone and there may be a risk of precipitating withdrawal syndrome. Adjustment of the dose of methadone should be considered. The concurrent use of MAOl's is contraindicated see 4. Drugs that acidify or alkalinise the urine may have an effect on clearance of methadone as it is increased at acidic pH and decreased at alkaline pH.

Naloxone and naltrexone antagonises the analgesic, CNS and respiratory depressant effects of methadone and can rapidly precipitate withdrawal symptoms See Section 4. Similarly buprenorphine and pentazocine may precipitate withdrawal symptoms. Based on the known metabolism of methadone, these agents may decrease plasma concentrations of methadone by increasing its hepatic metabolism. Methadone may increase the plasma concentration of zidovudine.

Narcotic withdrawal syndrome has been reported Green methadone pill patients treated with some retroviral agents and methadone concomitantly. Methadone maintained patients beginning antiretroviral therapy should be monitored for evidence of withdrawal and methadone dose should be adjusted accordingly.

Methadone may have an effect on other drugs as a consequence of reduced gastro-intestinal motility. Methadone clearance is decreased when co-administered with drugs which inhibit CYP3A4 activity, such as some anti-HIV agents, macrolide antibiotics, cimetidine and azole antifungal agents since the metabolism of methadone is mediated by the CYP3A4 isoenzyme. In patients taking drugs affecting cardiac conduction, or drugs which may affect electrolyte balance there is a risk of cardiac events when methadone is taken concurrently. The concomitant use of opioids with sedative medicines such as benzodiazepines or related drugs increases the risk of sedation, respiratory depression, coma Green methadone pill death because of additive CNS depressant effect.

The dose and duration of concomitant use should be limited see section 4. Methadone administered to pregnant women for the management of opioid addiction has the potential for several adverse effects on the foetus and neonate. Apart from the risk of prolonged respiratory depression in the neonate, the immediate problems are withdrawal syndrome in utero and following birth and low birth weight; increased stillbirth rates have also been reported.

The effects of methadone itself on pregnancy and infants born to methadone-treated mothers are difficult to assess in view of the complicating factors such as poor prenatal care, poor maternal nutrition, smoking, poor environmental and social conditions. Most studies have associated methadone with a low birth weight but methadone has not convincingly been associated with congenital malformations.

Methadone is excreted in breastmilk at low levels. The decision to recommend breast-feeding should take into clinical specialist advice and consideration should be given to whether the woman is on a stable maintenance dose of methadone and any continued use of illicit substances. If breastfeeding is considered, the dose of methadone should be as low as possible. Prescribers should advise breastfeeding women to monitor the infant for sedation and breathing difficulties and to seek immediate medical care if this occurs.

Although the amount of methadone excreted in breast milk is not sufficient to fully suppress withdrawal symptoms in breast-fed infants, it may attenuate the severity of neonatal abstinence syndrome. If it is necessary to discontinue breastfeeding it should be done gradually, as abrupt weaning could increase withdrawal symptoms in the infant.

The ability to drive or operate machinery may be severely affected during and after treatment with methadone. The time after which such activities can be safely d is extremely patient dependent and must be decided by the physician.

This medicine can impair cognitive function and can affect a patient's ability to drive safely. This class of medicine is in the list of drugs included in regulations under 5a of the Road Traffic Act When prescribing this medicine, patients should be told:.

Changes of mood, including euphoria, and hallucinations are occasionally reported. Drug dependence see section 4. Drowsiness and headache. Methadone has the Green methadone pill to increase intracranial pressure, particularly in circumstances where it is already raised. Bradycardia and palpitations can occur. Cases of QT prolongation and torsades de pointes have been rarely reported. Exacerbation of existing asthma, dry nose, respiratory depression particularly with larger doses. Reporting suspected adverse reactions after authorisation of the medicinal product is important.

Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at:www. Patients should be informed of the s and symptoms of overdose and to ensure that family and friends are also aware of these s and to seek immediate medical help if they occur. Serious overdosage is characterised by respiratory depression, extreme somnolence progressing to stupor or coma, maximally constricted pupils, skeletal muscle flaccidity, cold and clammy skin and sometimes bradycardia and hypotension.

In severe overdosage, particularly by the intravenous route, apnea, circulatory collapse, cardiac arrest and death may occur. Hypoglycaemia has been reported. Narcotic antagonists may be required but it should be remembered that methadone is a long acting depressant 36 - 48 hourswhereas antagonists act for 1 -3 hours, so Green methadone pill treatment with the latter must be repeated as needed.

An antagonist should not be administered, however, in the absence of clinically ificant respiratory or cardiovascular depression. Nalorphine 0. Oxygen, intravenous fluids, vasopressors and other supportive measures should be employed as indicated. In a person physically dependent on narcotics, Green methadone pill of the usual dose of a narcotic antagonist will precipitate an acute withdrawal syndrome: use of the antagonist in such a person should be avoided if possible, but if it must be used to treat serious respiratory depression, it should be administered with great care.

Pharmacotherapeutic group: Nervous system, other nervous system drugs, drugs used in addictive disorders, methadone. The analgesic activity of the race mate is almost entirely due to the 1-isomer, which is at Green methadone pill 10 times more potent as an analgesic than the d- isomer. The d-isomer lacks ificant respiratory depressant activity but does have anti-tussive effects.

These actions result in analgesia, depression of respiration, suppression of cough, nausea and vomiting via an effect on the chemoreceptor trigger zone and constipation. An effect on the nucleus of the oculomotor nerve, and perhaps on opioid receptors in the pupillary muscles causes pupillary constriction. All these effects are reversible by naloxone with pA2 value similar to its antagonism of morphine.

Like many basic drugs, Methadone enters mast cells and releases histamine by a non-immunological mechanism. It causes a dependence syndrome of the morphine type.
