Practical Management of MS in the Primary Care Office Setting Case Study 3
Case 3Managing Adverse Events • Ms. M, 23-year-old woman newly diagnosed with MS • Initiated on interferon beta-1a IM weekly – 1st dose 48 hours ago • Calls office today with complaints of horrible flu-like symptoms for over 24 hours after her 1st dose Discussion question: What triage questions should you ask her?
Case 3Triage Questions • Did she premedicate with any pain relievers/antipyretics? • Acetaminophen? NSAID? • Did she take any medication (eg, acetaminophen or NSAID) around the clock after dosing? • What dose of interferon beta-1a did she take?
Case 3Patient Responses • Ms. M did not premedicate • She did not use acetaminophen or NSAID postdose • She gave herself the full dose of interferon beta-1a; she did not know to titrate the dose
Case 3Instructions to Patient • Premedicate with naproxen 500 mg before administering interferon and then dose every 8−12 hours if needed • Reduce interferon beta-1a dose to ½ for 2 weeks, then ¾ dose for 2 weeks, then full dose • Follow up in clinic in about 1 month
Case 3Clinic Follow-Up 5 Weeks Later • Ms. M reports that she tolerated 1/2 dose and 3/4 dose without problem • She is having minor flu-like symptoms with full dose
Case 3Clinic Follow-Up 6 Months Later • Ms. M reports being “laid up” for 24 or more hours each week after interferon beta-1a dose • She is taking naproxen 500 mg before dosing and around the clock afterward • She has skipped the last few interferon doses and is thinking about discontinuing treatment completely because “it is just not worth it” Discussion question: What options would you discuss with her?
Case 3Options Discussed • Switch to a different disease-modifying therapy (especially glatiramer acetate) • Prednisone 10 mg weekly with interferon beta-1a IM dose • No treatment • She should be informed of the benefits of early disease-modifying therapy, which she would be losing by choosing no treatment
Case 3Ms. M’s Choice • Ms. M is engaged in a discussion regarding all of her options • She recognizes the benefits of early treatment, and indicates a desire to continue on some form of MS disease-modifying therapy • She does not want to inject more than once weekly, so she decides to continue interferon beta-1a IM but with the addition of prednisone • Another follow-up is scheduled in 1 month
Case 3Clinic Follow-Up 1 Month Later • Ms. M is tolerating interferon beta-1a at full dose • She has had minimal to no side effects with prednisone
