PATIENT COUNSELING

Poison Prevention Week is in March National Poison Prevention Week, March 20-26, provides a special opportunity for pharmacists to educate patients about avoiding accidental poisonings and handling pOisonings if they do occur. For more than 30 years, National Poison Prevention Week has focused consumers' attention on the importance of keeping dnlgs and chemicals out of children's reach. Thanks to increased public awareness, the number of children dying from poisoning decreased from 450 in 1961 to 55 in 1989. Educational materials are available each year from the Poison Prevention Week COlllcil and other sources. Key points they emphasize are: • Use child-resistant packaging. Even people without small children should use this packaging if there is any chance small children will visit. • Call a poison center or physician immediately if someone ingests a poison. Children under age five are especially at risk for accidental poisonings because they explore their environment by putting things in their mouths. And they cannot tell the difference between Vol. NS34, No.2

things that taste good-like candy or soda-and drugs or household cleaners. • Always read the label and follow instructions when taking medicines. Inspect the packaging and the product itself to protect against taking medicines that have been tampered with. • Store pesticides in locked cabinets or sheds. Follow the product's directions precisely. Keep children and their toys away from areas where pesticides are to be applied; keep them away llltil the chemicals are dry, or as recommended on the labels.

Although hypertension in elderly patients is common, it should not be viewed as normal or an inevitable consequence of aging, according to a report fmalized in November by the National High Blood Pressure Education Program. The report on hypertension in the elderly, and a companion report on hypertension in people with diabetes, provide an overview of hypertension's risks in these special populations and recommend treatments. The reports define "hypertension" as systolic blood pressure of 140 mmHg or higher, or diastolic blood pressure of 90 mmHg or higher-the same classification put forth in 1993 by the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure. The report on the elderly notes that variability of blood pressure according to when the measurement is taken is more pronounced in older people, as are the effects on blood pressure of food, position, and other influences. Other important points contained in the report: • Blood pressure should be reduced slowly and cautiously in the elderly. Lifestyle modifications should be tried before drug therapy is initiated. Key lifestyle changes include losing weight; getting aerobic exerAMERICAN PHARMACY

cise; limiting salt, fat, and alcohol intake; and avoiding smoking. • All classes of antihypertensive drugs are effective in older people. Although adverse drug reactions are two-to-three times more common in the elderly, there is no evidence that they tolerate certain antihypertensive drugs or classes less well than YOlmger patients do. • Health care professionals should reinforce to patients during every visit the importance of controlling hypertension and taking blood pressure medications as prescribed. • To encourage compliance, schedules for taking medications should be as simple as possible. Both verbal and written instructions should be provided. Other aids, such as refillable lmitdose dispensers, may be helpful. • Prescribing medications in small quantities until the drug of choice is established is helpful, especially for patients with limited incomes. The size of the tablet or capsule is an important consideration in this age group because some elderly people have difficulty swallowing. According to the report on hypertension with diabetes, patients with hypertension and diabetes are at higher risk for coronary heart disease, stroke, peripheral vascular disease, diabetic retinopathy, and end-stage renal disease, and are more likely to require amputations February 1994

of lower extremities. Although the general approach to treating hypertension in patients with or without diabetes is the same, special considerations must be taken into account for diabetic patients: • Diabetic patients whose blood pressures have been lowered to 140/90 mmHg remain candidates for further intervention. The recommended goal is 130/85 mmHg. • When making therapeutic decisions, the effects of a specific antihypertensive therapy on renal function and the progression of diabetic nephropathy must be considered. • Some therapies can have adverse effects on glucose and lipid metabolism. • Autonomic dysfunction, which can result in postural hypotension, is common with diabetes and must be taken into account when therapeutic decisions are made.

Public Lacks Knowledge on Genital Warts A recent survey of more than 1,200 Americans found that fewer than half had ever heard of genital warts. More than 90% of those unfamiliar Vol. NS34, No.2

with the condition believe they have no personal risk of contracting genital wartsdespite evidence that there is a 50% risk of transmission from a single sexual encounter with an infected partner. The survey, conducted by the Opinion Research Corporation for the Condyloma Education Council, also found that 49% of respondents do not know how to prevent genital warts. Genital warts, caused by the human papilloma virus (HPV), affects about eight million Americans, making it one of the four most common sexually transmitted diseases. The only foolproof way to avoid transmitting the warts is abstinence, because warts often occur in outlying genital areas on both men and women. According to Marcia Bowling, MD, a professor of

obstetrics and gynecology at the University of Cincinnati and a member of the council, "This is a virus that may exist outside the area protected by a condom -even if the warts are not visible. " After the warts are removed, the virus "remains in or on the skin and may cause the wart to reappear and infect or reinfect a sexual partner," she said. Some strains of HPV are believed to be associated with cervical cancer in women and other genital cancers. The warts, which appear as pink or flesh-colored cauliflower-like lesions, are unsightly and can be uncomfortable when they persist or recur. Symptoms may range from none at all, to itching; burning; tenderness; vaginal discharge; frequent urination or bleeding during urination, for men; or pain during sexual intercourse.

Hypertension May be Linked to Tension in Men Despite a lack of supporting medical evidence, people often think hypertension is linked in some way with nervous tension and anxiety. A recent study suggests that they may be right: in middle-aged men, at least, anxiety and anger may increase the risk for developing hypertension (lAMA. 1993;270:2439-43). Researchers followed 1,123 men and women for 18 to 20 years. All had nonnal blood pressure at the start of the study. Highly anxious middle-aged men were found to have twice the risk of developing hypertension compared with men in the same age group without tension symptoms. Among symptoms the researchers considered indicative of tension were headache; nervousness or shaking; feeling tense, restless, or worried; holding anger in; and taking anger out on others. An association between tension and hypertension was found neither in women, whether they worked in or outside the home, nor in elderlymen.

Although people with multiple sex partners are at greatest risk for contracting genital warts, they can be spread from any skin-to-skin contact, and even by sharing underwear or bath towels. Treatments include topical solutions such as podophyllin and trichloroacetic acid, surgical removal, cryotherapy, electrocautery, laser therapy, or repeated injections of alpha interferon-the only treatment that attacks the underlying HPV infection.
