a. oxycodone HCl, 2.25 mg; oxycodone terephthalate, 0.19 mg; aspirin, 325 mg
This schedule II pain reliever contains oxycodone, a potent opioid analgesic, and aspirin, a nonopioid analgesic. Your patient may feel drowsy or dizzy while taking it.
b. pseudoephedrine HCl, 120 mg; guaifenesin, 600 mg
Prescribed to relieve cough and cold symptoms, this time-release tablet contains pseudoephedrine, a nasal decongestant, and guaifenesin, an expectorant. Tell your patient to call her health care provider if she feels nervous or dizzy or has trouble sleeping.
c. sodium acid phosphate, 500 mg; methenamine mandelate, 500 mg
This medication is given to prevent chronic, recurrent urinary tract infections. Sodium acid phosphate acidifies the urine, which methenamine needs to hydrolyze to bactericidal formaldehyde.
d. dipyridamole, 200 mg; aspirin, 25 mg
This extended-release combination helps prevent recurrent transient ischemic attacks or stroke. Dipyridamole, an antiplatelet agent, and aspirin work together to prevent blood clot formation. Both interact with various other drugs, so tell your patient to check with his health care provider before taking any overthe-counter or prescription medications.
e. ethinyl estradiol, 35 or 50 mcg; ethynodiol diacetate, 1 mg
A woman with dysmenorrhea is likely to see an improvement in her cycle after a few months taking this combination. Ethinyl estradiol is an estrogen and ethynodiol diacetate a progestin. To help your patient comply with treatment, tell her to take the medication at the same time every day.
