Patient teaching for Sympathomimetic’s
- The patient should take the medication as directed by the physician or other health care provider; the dosage should not be changed
- Overuse of these drugs may result in severe side effects.
- The physician should be contacted if the drug is not helping the patient.
- Contact the health care provider if bronchial irritation, dizziness, chest pain, insomnia, or any change in symptoms occurs.
- Drinking lots of fluid, especially water, makes the mucus thinner and helps the medication work better.
- The patient must not take any other medications without checking first with the physician or other health care provider.
- The patient should take the last dose a few hours before bedtime so that the drug does not produce insomnia

Patient teaching for Xanthines
- The patient should take the medications as ordered; this often means every 6 hours if taking a sustained release medication.
- Any unusual symptoms should be reported to the physician-especially seizures, rapid heartbeat, irregular heartbeat, vomiting, dizziness, and irritability.
- The patient should avoid drinking large amounts of caffeine-containing drinks such as tea, coffee, cocoa, and cola drinks.
- The patient should avoid taking any other drugs without first checking with the physician. This includes drugs that may be bought over the counter; they may also have an effect on the respiratory system.
- If a dose is missed and noticed within an hour, the patient should take the prescribed dose as soon as possible. I more than an hour has passed, the dose should be skipped and the patient should stay on the original dosing schedule.
- Some suppositories must be refrigerated, whereas others may not. Check with the pharmacist about this.
- The physician should be called if use of suppositories causes burning or irritation of the rectal area.
What are intranasal steroids
- a. The main action of topical intranasal steroids in an anti-inflammatory effect, which decreases local congestion. They are used to treat allergic, mechanical, or chemically induced local nasal inflammation or nasal polyps only when the more usual treatment has been tried and found to not work. Adverse reactions to intranasal steroids include asthma, nasal irritation and dryness, nausea, nosebleeds, perforation of the nasal septum, bad taste and smell, rebound congestion and skin rash. The patient should not use these drugs if an infection is present.
- prednisolone (Pediapred, Delta-Cortef)
- prednisone ( Meticorten)
- methylprednisolone (Medrol)
specialconsideration with the geriatric patient with intranasal steroids
a. Elderly patients are highly sensitive to these drugs and should be carefully watched for CNS stimulation. The physician may need to be contacted and doses may need to be altered.
whatmay affect theophylline (Elixophyllin)
Drinking or eating foods high in caffeine, like coffee, tea, cocoa, and chocolate, may increase the side effects caused by theophylline. Avoid large amounts of these substances while you are taking theophylline. Also the half life is shorter in people who smoke as appose to people who don’t smoke.
how do Antihistamines work?
- block the action ofhistamine by competing with it for the H_1 receptor site on the effectorstructures… The blocking action limits the vasodilatation (opening) andincreased capillary permeability and reduces the edema (swelling) caused byhistamine. Antihistamines also have asedative effect on the central nervous system. Cetirizine (Zyrtec) , fexofenadine (Allegra ), loratadine (Claritin) , hydroxyzine (Vistaril) , promethazine (Phenergan), diphenhydramine (Benadryl)
How do Antitussives
narcotic Antitussives suppress the cough reflex by acting directly on the cough center in the medulla of the brain. Non-narcotic Antitussives reduce the cough reflex at its sources by anesthetizing stretch receptors in respiratory passages, lungs and pleura, and by decreasing their activity. codeine phosphate hydrocodone (Hycodan)
How does Cromolyn sodium work? Asthma.
a. Cromolyn sodium helps treats asthma by slowing down the destruction of sensitized mast cells. As mast cells are destroyed, they release histamine and the slow-reacting substance of anaphylaxis created by breathing in specific antigens.
How do Bronchodilators work?
- Bronchodilators the main action of sympathomimetic’sbronchodilators (adrenergic stimulants) in asthma and other respiratorydiseases is to relax the smooth muscle cells of the bronchi by stimulatingbeta_2- adrenergic receptors. They alsostimulate alpha adrenergic receptors, which produce a vasoconstriction responseall through the body (systemically), especially a narrowing or constriction inthe blood vessels of the bronchialmucosa. This results in less mucosal and submucosal edema.
- levalbuterol (Xopenex) , , ipratropium (Atrovent)
how do Sympathomimetic’sbronchodilators work?
- Sympathomimetic’s bronchodilators stimulate beta_1 receptors, which results in an increased rate and force of theheart’s contractions.
- albuterol (Proventil), ephinephrine (Adrenalin Chloride)
how do Xanthines work?
act directly to relax the smooth muscle cells of the bronchi thereby dilating or opening up the bronchi, and blood vessels in the lungs. These drugs also act directly on the kidneys to produce diuresis (increased production and excretion of urine). These drugs cause CNS effects. theophylline (Elixophyllin)
how do Leukotriene receptorinhibitors work?
a. belong to the newest category of drugs used in treating asthma. These are not bronchodilators but act to block receptors for the cysteinyl leukotrienes C_4, D_4 and E_4 cysteinyl leukotrienes. These drugs are rapidly absorbed orally. Food interferes with their absorption, so they should be taken on an empty stomach. montelukast sodium (Singular)
how do Corticosteroids work?
- arethe most potent (powerful) and consistently effective medications for thelong-term control of asthma. Theiraction on the inflammatory process may account for their effectiveness. They block the reaction to allergens andreduce airway hyper responsiveness. --
- : triamcinolone acetonide (Azmacort) ,
- Budesonide (Pulmicort Turbuhaler) ,
- fluticasone (Flovent or Flonase)
- prednisolone (Pediapred, Delta-Cortef)
- prednisone ( Meticorten)
- methylprednisolone (Medrol)
How do Decongestants work
- Decongestants directly affect the alphareceptors of blood vessels in the nasal mucosa, causing vasoconstriction. This action reduces blood flow, fluidmovement, and mucosal edema. Many agentsalso act on beta receptors, which may cause rebound vasodilatation, or anincrease in blood flow leading to further congestion. This problem is commonly seen with prolongeduse of the medication
- oxymetazoline (Afrin)
- pseydoephedrine sulfate (Sudafed)
How do Expectorants work?
- They decrease the thickness of respiratory secretions and aid in their removal. It is believed they work by increasing the amount of fluid in the respiratory tract.
- guaifenesin (Robitussin, Mucinex, & Mytussin)
Patient teaching for Cromolyn Antitussives

Patient teaching for Decongestants
- These meds are OTC meds. They should be carefully used and the HCP should be told whether they are on these or not
- Also not for little children
Patient teaching for Expectorants
- Pt should be aware that these drugs will help make the sputum more liquid. This will make it easier to bring sputum up when the pt coughs.
- The pt should use a humidifier and drink at least 2 quarts of water daily while taking an expectorant. These actions will help get the mucus out
- HCP should be notified if the cough is present wit ha high fever, rash or persistent headaches, or if the cough returns once the pt thinks it has been under control
- The pt should use the med only in the dosage recommended to decrease chances of side effects
Patient teaching for Topical Intranasal Steroids
- The pt should not use these drugs if an infection is present. Pts should notify the HCP if an infection develops while taking this drug
- The pt should not exceed the prescribed dosage and frequency.
- There may be temporary dryness and irritation of the nose
- When stopping this drug, the dosage must be tapered slowly and not stopped suddenly
- The HCP should be notified if symptoms do not improve or if they get worse
What is the best way to assure thet the antibiotic will be effective?
a. The best way to assure that the antibiotic will be effective is to have the organism responsible for the infection to be identified by a culture. The patient needs to take the medication exactly as prescribed for as long as prescribed, and not stop because of feeling better. Every dose should be taken. Avoid Bacteriostatic antibiotics such as tetracycline and erythromycin because these drugs can decrease the bactericidal effect of other antibiotics especially Penicillin. Avoid antacids especially with Penicillin because it may decrease the absorption of the antibiotic. Also many antibiotics interfere with the action of birth control pills, leaving women at risk of pregnancy. Tell women on birth control on antibiotics to use a backup method for protection.
- a. Aminoglycosides is an antibiotic b. And may cause significant damage to the kidney (nephrotoxicity) or ears (ototoxicity).
- c. Bacitracin may cause renal failure as a result of tubular and glomerular necrosis; therefore, the patient’s renal status must be closely monitored. It is effective in treatment of gram-negative infections when penicillin contraindicated.
- d. An adverse reaction with aminoglycosides would be significant renal toxicity, which is usually reversible; risk of toxicity increases in patients with renal impairment. Significant auditory and vestibular ototoxicity may occur in patients on prolonged therapy or those taking higher than recommended dosages
- .e. Aminoglycosides have a narrow therapeutic rage, so closely monitor blood levels of these drugs to avoid toxic levels. Dosage is calculated on the basis of the patient’s weight and is increased or decreased based on blood levels so an effective level is maintained. The narrow therapeutic range (when the lowest and highest acceptable drug levels are not far apart) requires that the sample for the antibiotic blood level be drawn just before the next scheduled dose is given. This sample will show the lowest blood level of the antibiotic (found at the “trough”), rather than a blood level at a higher range (at or near the “peak”). The lowest blood level will determine whether the dosage needs to be adjusted to stay within the therapeutic range and not go above the toxic level or below the effective level. Because of the nephrotoxicity of these agents, blood urea nitrogen and creatinine levels must also be monitored during the course of therapy.
Adverse vs.side effect
- a. Side Effect: Any effect of a drug, chemical, or other medicine that is in addition to its intended effect, especially an effect that is harmful or unpleasant.
