Patients did not exhibit the withdrawal symptoms when melatonin was used in combination with increased all-day light exposure provided by increasing overhead lighting in the assisted living facility. C were interested in trying melatonin in combination with increasing her daytime light exposure, so melatonin, 3 mg immediate release, 1 tablet at bedtime was prescribed. C would need to be followed closely for depressive symptoms because of the increased risk described above. C has made a conscious effort to ensure that the drapes are open and that the room is bright when Mrs. She also reports that "various aches and pains in her body are not as bad and that she has not had as much trouble settling down at night. Sharkey again in 6-to 9 months but is encouraged to return sooner if symptoms worsen. If acquiring a bright light box is not feasible, teaching patients and their families about outdoor light exposure and increasing the brightness of ambient lighting may be effective. If clinicians and patients want to do a trial of melatonin, patients should be monitored closely for sedation and mood symptoms. Melatonin in combination with bright light may be effective, however, and more studies are needed in this area. Sleep Strategies for Teens With Autism Sleep strategie for teens with auti Strategies and tools to help parents improve sleep for teens with these materials are the product of on-going activities of the Autism Speaks Autism Treatment Network, a funded program of Autism Speaks. These problems are often related, so creating habits that help someone fall asleep more easily may also help them stay asleep during the night. Trouble falling asleep Waking often at night the ideas presented here are based on research and on the experience of sleep experts. This brochure will focus on healthy sleep habits that you can help your teen put into place. Even if you have tried these strategies when your child was younger, it may be helpful to revisit them now that your child is a teen. Make sure your teen has a say in what new habits and routines he/she wants to try. The changes will be easiest and work best if everyone who helps your teen with daily routines knows and uses the strategies you and your teen choose. Regular Schedule There are activities teens can do during the day that will help them sleep better at night. Waking up and getting out of bed about the same time each day is as important as going to bed about the same time each night. Open the curtains Change out of sleep clothes Get some exercise Spend time in the sunlight Try to avoid naps p. Family dinners are encouraged, but if they are heavy meals, try to serve them several hours before bedtime. Just be sure to try to avoid foods and drinks that contain caffeine, particularly in the 3 to 4 hours before bedtime. Milk and fruit juices do not contain caffeine and are safe choices for afternoon and evening meals or snacks. This means slowly cutting down exciting, busy activities and choosing things that relax your teen. Different people relax in different ways so you may need to decide what is and what is not calming. Sleep Having a schedule like this that you and your teen can look at each evening can help him/her keep the same basic order. Post the schedule of activities where it is most likely to help your teen remember the schedule. Having pictures or a checklist can help some teens remember to keep the routine in the same order every night.

However, the marked increase in lovastatin levels that occurred with these flavonoids in the animal study, and the known important interaction of grapefruit juice (which is a rich source of flavonoids) with lovastatin and simvastatin (leading to rhabdomyolysis and myopathy), suggest that kaempferol and naringenin supplements should generally be avoided in patients taking these statins. Comparison of in vitro hepatic models for the prediction of metabolic interaction between simvastatin and naringenin. In vitro inhibition of simvastatin metabolism in rat and human liver by naringenin. Constituents the seeds contain a fixed oil, composed of glycerides of linoleic and linolenic acid. The seeds also contain: mucilage; the lignans secoisolariciresinol and its diglucoside; and the cyanogenetic glycosides linamarin and lotaustralin. Pharmacokinetics Ingested lignans such as secoisolariciresinol have been shown to undergo bacterial hydrolysis and metabolism to produce the mammalian lignans enterolactone and enterodiol, which have oestrogenic effects. Use and indications Flaxseed was formerly used as a demulcent and soothing emollient agent for bronchitis and coughs, and applied externally to burns. More recently, flaxseed oil has been used to lower blood-cholesterol levels, and flaxseed extract is being taken as a form of hormone replacement therapy due to its phytoestrogenic effects, thought to be due to the Interactions overview Flaxseed lignan supplementation appears to have no significant effect on blood-glucose levels in type 2 diabetic patients also taking oral antidiabetic drugs (not named). Limited evidence suggests that flaxseed oil may increase bleeding times and therefore some caution might therefore be appropriate with aspirin and anticoagulants. F 195 196 Flaxseed Clinical evidence In a randomised, crossover study in 68 patients with type 2 diabetes and mild hypercholesterolaemia, taking a supplement containing a total of 360 mg of flaxseed lignan daily for 12 weeks had no significant effect on blood-lipid profile, insulin resistance, fasting glucose and insulin concentrations. In this particular study, patients continued to take their usual medication, which included oral antidiabetics and lipid-lowering medications, none of which was specifically named in the study. Patients taking insulin were also excluded from this study; however, information on other concurrent medication was not reported. Importance and management It appears from these studies that flaxseed oil or lignans have minimal effects on glycaemic control in type 2 diabetes, and in one study the lignans had no additive blood-glucose-lowering effects with oral antidiabetic drugs (not named). Flaxseed is therefore unlikely to affect the blood-glucose-lowering efficacy of concurrent antidiabetic medication.

Effects of a flaxseed-derived lignan supplement in type 2 diabetic patients: a randomised, double-blind, cross-over trial. High dose flaxseed oil supplementation may affect blood glucose management in human type 2 diabetics. Flaxseed dietary supplement versus hormone replacement therapy in hypercholesterolemic menopausal women. Flaxseed + Anticoagulant or Antiplatelet drugs Limited evidence suggests that flaxseed oil may have some antiplatelet effects, which could be additive with those of conventional antiplatelet drugs, and increase the risk of bleeding with anticoagulants. Clinical evidence Two case reports briefly describe increased bleeding (haematuria and nosebleeds) in patients taking aspirin and flaxseed oil, one of whom was taking low-dose aspirin. Mechanism Omega-3 fatty acids such as linolenic acid are thought to have some antiplatelet effects and might therefore prolong bleeding time. Theoretically, this effect might be additive to that of other antiplatelet drugs, and increase the risk of bleeding with anticoagulants. Importance and management the general significance of these reports is unclear and no interaction has been established. Nevertheless, a large epidemiological study would be needed to quantify any excess risk in the order of that seen with antiplatelet doses of aspirin taken with warfarin. As with high doses of fish oils (marine omega-3 fatty acids), it may be prudent to use some caution with the concurrent use of high doses of flaxseed supplements in patients also taking aspirin or anticoagulants. Dietary -linolenic acid alters tissue fatty acid composition but not blood lipids, lipoproteins or coagulation status in humans. A double-blind, placebocontrolled and randomized study: flaxseed vs safflower seed. Flaxseed + Antidiabetics Flaxseed lignan supplementation appears to have no significant effect on blood-glucose levels in type 2 diabetic patients also taking oral antidiabetic drugs. Pharmacokinetics For information on the pharmacokinetics of an anthraquinone glycoside present in frangula, see under aloes, page 27. Interactions overview No interactions with frangula found; however, frangula (by virtue of its anthraquinone content) is expected to share some of the interactions of a number of other anthraquinonecontaining laxatives, such as aloes, page 27 and senna, page 349. Of particular relevance are the interactions with corticosteroids, digitalis glycosides and potassium-depleting diuretics. The frangulosides are the main components, which include frangulin A and B, emodin derivatives, chrysophanol and physcion glycosides, and free aglycones.

Interactions overview An isolated case of lithium toxicity has been reported in a patient who took a herbal diuretic containing horsetail among other ingredients, see under Parsley + Lithium, page 305. For information on the interactions of individual flavonoids present in horsetail, see under flavonoids, page 186. Horsetail + Lithium `For mention of a case of lithium toxicity in a woman who had been taking a non-prescription herbal diuretic containing corn silk, Equisetum hyemale, juniper, buchu, parsley and bearberry, all of which are believed to have diuretic actions, see under Parsley + Lithium, page 305. Note that this case was with Equisetum hyemale, which is not the species more commonly used (Equisetum arvense). H Isoflavones Isoflavonoids this is a large group of related compounds with similar structures and biological properties in common, which are widely available as additives in dietary supplements as well as the herbs or foods that they were originally derived from. Isoflavones are the subject of intensive investigations and new information is constantly being published. The information in this monograph relates to the individual isoflavones, and the reader is referred back to the herb (and vice versa) where appropriate. It is very difficult to confidently predict whether a herb that contains one of the isoflavones mentioned will interact in the same way. The levels of the isoflavone in the particular herb can vary a great deal between specimens, related species, extracts and brands, and it is important to take this into account when viewing the interactions described below. Types, sources and related compounds Isoflavones are plant-derived polyphenolic compounds that are a distinct group of flavonoids, page 186. Most occur as simple isoflavones, but there are other derivatives such as the coumestans, the pterocarpans and the rotenoids, some of which also have oestrogenic properties. The isoflavones are found in small amounts in many legumes, seeds, grains and vegetables, but soya, page 356, is by far the most concentrated dietary source; it contains principally genistein and daidzein. There are various other isoflavone-rich supplements, including those derived from alfalfa, page 21 and red clover, page 332 (both of which are rich in biochanin A and formononetin), and kudzu, page 267, which contains puerarin. In addition, some popular herbal medicines, such as astragalus, page 46 and shatavari, page 353 contain isoflavones as well as other types of active constituents. The most important isoflavones are: genistein and daidzein, which are hydrolysed from their glycosides genistin, daidzin and puerarin (daidzein 8-C-glucoside); glycetein and its glycoside glycitin; formononetin, biochanin A, isoformononetin, prunetin, calycosin, ononin, orobol; and others. I used for these possible benefits, it remains to be seen whether they are effective. Isoflavones have weak oestrogenic effects, but under certain conditions (for example, in premenopausal women) they can also act as oestrogen antagonists by preventing the more potent natural compounds, such as estriol, from binding to receptor sites. Isoflavones also inhibit the synthesis and activity of enzymes involved in oestrogen and testosterone metabolism, such as aromatase. Because of their oestrogenic effects, isoflavone supplements have been investigated for treating menopausal symptoms such as hot flushes (hot flashes)1,2 and for prevention of menopausal osteoporosis,3 with generally modest to no benefits when compared with placebo in randomised controlled studies. Isoflavones have also been extensively studied for lipid lowering,4 and there are a few studies on other cardiovascular benefits, and effects on cognitive function. In a 2006 analysis, the American Heart Advisory Committee concluded that the efficacy and safety of soya isoflavones were not established for any indication and, for this reason, they recommended against the use of isoflavone supplements in food or pills. Isoflavone glycosides are probably hydrolysed in the gut wall by intestinal beta-glucosidases to release the aglycones (genistein, daidzein, etc. Gut bacteria also extensively metabolise isoflavones: for example, daidzein may be metabolised to equol, a metabolite with greater oestrogenic activity than daidzein, but also to other compounds that are less oestrogenic. Although isoflavone supplements are 258 Isoflavones about one-third of Western individuals metabolise daidzein to equol. The elimination half-life was not significantly altered after repeated administration. The authors concluded that three times a day dosing is recommended, as accumulation will not occur, and plasma levels remain at levels that are biologically active, even 8 hours after the last steady-state dose. In an in vitro study in human liver microsomes, fluvoxamine was a potent inhibitor of genistein and tangeretin metabolism. The relevance of this to the activity of these isoflavones is unknown, since the relative activity of the metabolites to the parent isoflavone is unknown. This highlights the problems of extrapolating the findings of in vitro studies to the clinical situation. Some of these may be directly applicable to isoflavone supplements; however, caution must be taken when extrapolating these interactions to herbs or foods known to contain the isoflavone in question. This is because the amount of the isoflavone found in the herb or food can be highly variable, and might not be known, and other constituents present in the herb or food might affect the bioavailability or activity of the isoflavone.
