Two other second-generation agents order cleocin gel with a mastercard acne prescriptions, azelastine [Astelin purchase cheapest cleocin gel and cleocin gel acne essential oils, Astepro] and olopatadine [Patanase] cheapest generic cleocin gel uk acne light mask, both used for local effects in the nose, are discussed in Chapter 60. Fexofenadine [Allegra, Allegra Allergy] is approved for oral therapy of seasonal allergic rhinitis and for chronic idiopathic urticaria. Of the second-generation antihistamines now available, fexofenadine appears to offer the best combination of efficacy and safety. In clinical trials, the incidence of drowsiness and other side effects was nearly the same as with placebo. To ensure fexofenadine absorption, patients should not drink fruit juices within 4 hours before dosing or 1 to 2 hours after dosing. Cetirizine is eliminated by a combination of hepatic metabolism and renal excretion. Although cetirizine is generally well tolerated, it can cause drowsiness, fatigue, and dryness of the mouth, nose, and throat. Cetirizine—and levocetirizine, its active isomer—cause more sedation than the other second-generation antihistamines, but less sedation than the first-generation drugs. Cetirizine is available in standard tablets (5 mg), chewable tablets (5 and 10 mg), orally disintegrating tablets (10 mg), and a syrup (1 mg/mL). Dosage should be reduced in patients with significant hepatic or renal impairment. Like cetirizine, levocetirizine is more sedating than the other second-generation antihistamines but less sedating than the first-generation agents. The most common side effects are drowsiness, fatigue, muscle weakness, and dry mouth. Dosing should be reduced in adults with mild to moderate renal impairment, and children with any degree of renal impairment should not use the drug. Loratadine [Claritin, Alavert, others] is approved only for seasonal allergic rhinitis. Like other second-generation antihistamines, the drug is generally well tolerated. However, in clinical trials, 8% of patients experienced drowsiness, and 12% experienced headache. The drug undergoes extensive hepatic metabolism and has a half-life of 8 to 28 hours. Loratadine is available in five formulations: a syrup (1 mg/mL), 10-mg liquid-gels, 10-mg standard tablets, 10-mg orally disintegrating tablets [Alavert], and 10-mg rapidly disintegrating tablets [Claritin RediTabs] designed to dissolve on the tongue. For patients with significant hepatic or renal impairment, dosing should be done every other day. Desloratadine [Clarinex, Clarinex RediTabs, Aerius ] is the major active metabolite of loratadine. The two drugs differ primarily in that desloratadine has a longer half-life (27 hours vs. However, although desloratadine has a longer half-life, there is no proof that its effects persist longer. Approved indications are seasonal allergic rhinitis, perennial allergic rhinitis, and chronic idiopathic urticaria.

Understand which health maintenance studies should be performed for a patient older than 65 years buy discount cleocin gel 20gm acne jeans review. Understand that preventive maintenance consists of immunizations order cleocin gel master card acne 1cd-9, cancer screening generic cleocin gel 20 gm with mastercard acne 7061, and screening for common diseases. Co n s i d e r a t i o n s The approach to health maintenance consists of three parts: (1) screening for cancer, cardiovascular disease or other conditions, (2) immunizations, and (3) behavioral counseling regarding healthy behaviors such as regular exercise and tobacco cessation. For a 66-year-old woman, this in cludes mammograph y for breast can cer screen in g, colon can cer scr een in g, t et anu s boost er ever y 10 year s, pn eu mococcal vaccin e, an d year ly in flu en z a im m u n iz at ion. S cr een in g for h yp er ch olest er olem ia ever y 5 year s up to age 75 and fasting blood glucose levels every 3 years also are recommended. The most common cause of mortality in men or women over 65 is cardiovascular disease. Cervical cancer screening can be stopped at age 65 if all previous Pap smears have been normal. An optimal screening test has high sensitivity and specificity, is inexpensive, and is easy to perform. Immunizations: Aside from childhood immunizations, routine adult immu- nizations include influenza, pneumococcal, diphtheria, tetanus, and acellular pertussis (Td/ Tdap), zoster, as well as others in certain situations such as hepatitis A or B vaccines. Behavioral counseling: I n q u ir y a n d co u n s elin g r ega r d in g r egu la r exer cis e, avo id - ance or cessat ion of tobacco, moderate alcohol use, or screening for depression. Chemoprevention: Use of medication to prevent disease, such as use of folate during pregnancy to prevent neural tube defects, or low-dose aspirin to prevent car diovascu lar event s. Screening: Ident ificat ion of disease or risk fact ors in an asympt omat ic pat ient. Of these preventive measures, screening requires firm medical evidence that it may offer benefit, and thoughtful consideration from the practitioner before he or she initiates screening, and recommends to an asymptomatic patient that he/ she undergoes a medical intervention with potential harms (such as cost, radiation exposure, anxiet y regarding false-posit ive t est s, biopsies, or ot her follow-up examinat ions). Facilities for diagnosis and treatment of the condition should be available to the patient. There needs to be a latent or preclinical stage of the disease in which it can be detected. The natural history of the disease should be understood to guide intervention or treatment. The cost of case-finding should be balanced within the context of overall medical expenditures. Using these criteria, one may deduce that it would not be useful to screen for Alzheimer dementia since there is no curative treatment and no evidence that early int ervent ion alters t he course of t he disease, or t o perform cancer screening in developing count ries where t reat ment facilit ies may not be available or acces- sible to large port ions of the populat ion. Among Americans bet ween ages 15 and 45, accident s and homicide are t he leading causes of deat h, so prevent ive care may include counseling regarding behavioral risk reduction, such as seatbelt use, avoiding alcohol or texting while driving, or substance abuse. After age 45, the leading causes of death are malig- nancy and cardiovascular disease, so screening is focused on risk factor reduction for t h ose diseases (such as t obacco cessat ion, or cont rol of blood pressure and hyperlipidemia), or early detection of cancers. Regarding cancer screening tests, the American Cancer Society and various subspecialty organizations publish var io u s r ecom m en d at ion s, wh ich are oft en n o t in agr eem en t. Rout ine immunizat ions include annual influenza vaccine (especially import ant in the geriat ric populat ion, since > 90% of influenza-related deat hs occur in pat ient s over 60 years), pneumo- coccal vaccin es (23-valent polysacch ar ide vaccin e an d 13-valent pn eumococcal con - jugat e vaccin e sh ou ld be given sequ ent ially), an d H er pes zost er vaccin e for pat ient s over age 60. O ffering cancer screening to older patients should consider estimated life expect ancy (t ypically at least 10 years), comorbid condit ions, and abilit y or will- ingness to undergo cancer t reat ment if a cancer is detected (eg, to tolerate a hemi- colectomy if a colon cancer is found).
