Peds: Monitor growth, both height and weight, in children on long-term therapy. May produce a false sense of euphoria and well-being. Provide frequent rest periods and observe patient for rebound depression after the effects of the medication have worn off. Usual Dosage & Route: PO and transdermal. PO: Administer immediate and sustained-release tablets on an empty stomach (30- 45 min before a meal). Sustained-release tablets should be swallowed whole; do not break, crush, or chew.

Information Patient Needs: Emphasize the importance of continuing to take this medication, even if feeling well. Instruct patient to take medication at the same time each day; last dose of the day should be taken at bedtime. Take missed doses as soon as remembered; do not double doses. If more than 2 doses in a row are missed, consult health care professional. Must be discontinued gradually to avoid sudden increase in BP. Hydralazine controls but does not cure hypertension. Encourage patient to comply with additional interventions for hypertension (weight reduction, low-sodium diet, smoking cessation, moderation of alcohol intake, regular exercise, and stress management). Instruct patient and family on proper technique for BP monitoring. Advise them to check BP at least weekly and report significant changes. Patients should weigh themselves twice weekly and assess feet and ankles for fluid retention. May occasionally cause drowsiness. Advise patient to avoid driving or other activities requiring alertness until response to medication is known. Caution patient to avoid sudden changes in position to minimize orthostatic hypotension. Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications, especially cough, cold, or allergy remedies. Instruct patient to notify health care professional of medication prior to treatment or surgery. Advise patient to notify health care professional immediately if general tiredness; fever; muscle or joint aching; chest pain; skin rash; sore throat; or numbness, tingling, pain, or weakness of hands and feet occurs. Vitamin B6 (pyridoxine) may be used to treat peripheral neuritis.

Trade Name/Generic Name: Demerol (meperidine)*

Classifications: Opioid Uses/Actions: For the treatment of severe pain requiring an opioid analgesic and for which alternative treatments are inadequate. Contraindications: Meperidine is contraindicated for use in patients with significant respiratory depression and in patients with acute or severe asthma (e.g., status asthmaticus) in unmonitored care settings or in the absence of resuscitative equipment. Additionally, avoid coadministration with other CNS depressants when possible, as this significantly increases the risk for profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate; if concurrent use is necessary, use the lowest effective dosages and minimum treatment durations needed. Monitor patients closely for signs or symptoms of respiratory depression and sedation. In patients with chronic obstructive pulmonary disease (COPD), cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, respiratory insufficiency, upper airway obstruction, or preexisting respiratory depression, it is recommended that non-opioid analgesics be considered as alternatives to meperidine, as even usual therapeutic doses may decrease respiratory drive and cause apnea in these patient populations. Extreme caution should also be used in patients with chronic asthma, kyphoscoliosis (a type of scoliosis), hypoxemia, or paralysis of the phrenic nerve. Patients with advanced age, debilitation, or sleep apnea are at an increased risk for the development of respiratory depression associated with meperidine. Use with caution in patients with obesity as this is a risk factor for obstructive sleep-apnea syndrome and/or decreased respiratory reserve. Meperidine should not be used during impaired consciousness or coma, as significant decreases in respiratory drive may lead to adverse intracranial effects from carbon dioxide retention. Respiratory depression, if left untreated, may cause respiratory arrest and death. Symptoms of respiratory depression include a reduced urge to breathe, a decreased respiratory rate, or deep breaths separated by long pauses High addiction rate. Nursing Implications: Take apical pulse before administering. If <50 bpm or if arrhythmia occurs, withhold medication and notify, administer metoprolol with meals or directly after eating.

Trade Name/ Generic Name: Proventil (albuterol)*

Uses/Actions: Binds to beta2-adrenergic receptors in airway smooth muscle, leading to activation of adenyl cyclase and increased levels of cyclic-3, 5-adenosine monophosphate (cAMP). Increases in cAMP activate kinases, which inhibit the phosphorylation of myosin and decrease intracellular calcium. Decreased intracellular calcium relaxes smooth muscle airways. Relaxation of airway smooth muscle with subsequent bronchodilation. Relatively selective for beta2 (pulmonary) receptors. Therapeutic Effects: Bronchodilation. Contraindications: Cardiac disease; Hypertension; Hyperthyroidism; Diabetes; Glaucoma; Seizure disorders; Excess inhaler use may lead to tolerance and paradoxical bronchospasm; OB, Lactation, Pedi: Safety not established for pregnant women near term, breast-feeding women, and children less than 2 years' old. Side Effects: nervousness, restlessness, tremor, headache, insomnia (occurs more frequently in young children than adults), hyperactivity in children, paradoxical bronchospasm (excessive use of inhalers), chest pain, palpitations, angina, arrhythmias, hypertension, nausea, vomiting, hyperglycemia, and tremor. Nursing Implications: Assess lung sounds, pulse, and BP before administration and during peak of medication. Note amount, color, and character of sputum produced. Monitor pulmonary function tests before initiating therapy and periodically during therapy. Observe for paradoxical bronchospasm (wheezing). If condition occurs, withhold medication and notify health care professional immediately. Usual Dosage & Route: the usual dosage for adults and children 4 years of age and older is two inhalations repeated every 4 to 6 hours. More frequent administration or a larger number of inhalations is not recommended. In some patients, one inhalation every 4 hours may be sufficient. Each actuation of PROVENTIL HFA Inhalation Aerosol delivers 108 mcg of albuterol sulfate (equivalent to 90 mcg of albuterol base) from the mouthpiece. Proventil (albuterol sulfate) Inhalation Aerosol is supplied as a pressurized aluminum canister, with an attached dose indicator, a yellow plastic actuator and orange dust cap each in boxes of one. Each actuation delivers 120 mcg of albuterol sulfate from the valve and 108 mcg of albuterol sulfate from the mouthpiece (equivalent to 90 mcg of albuterol base). Canisters with a labeled net weight of 6.7 g contain 200 inhalations Information Patient Needs: Instruct patient to take albuterol as directed. If on a scheduled dosing regimen, take missed dose as soon as remembered, spacing remaining doses at regular intervals. Do not double doses or increase the dose or frequency of doses. Caution patient not to exceed recommended dose; may cause adverse effects, paradoxical bronchospasm (more likely with first dose from new canister), or loss of effectiveness of medication. Instruct patient to contact health care professional immediately if shortness of breath is not relieved by medication or is accompanied by diaphoresis, dizziness, palpitations, or chest pain. Instruct patient to prime unit with 4 sprays before using and to discard canister after 200 sprays.
