Side effects definition

Side effects. The most common side effects reported in the trials were peripheral oedema, nausea, dizziness, fatigue, and ascites. Drug interactions (see also above under cautions): There is no experience regarding administration of rifaximin to subjects who are taking another rifamycin antibacterial agent to treat a systemic bacterial infection. In vitro data show that rifaximin did not inhibit the major cytochrome P-450 (CYP) drug metabolizing enzymes (CYPs1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A4). In in vitro induction studies, rifaximin did not induce CYP1A2 and CYP 2B6 but was a weak inducer of CYP3A4. In healthy subjects, clinical drug interaction studies demonstrated that rifaximin did not significantly affect the pharmacokinetics of CYP3A4 substrates, however, in hepatic impaired patients it cannot be excluded that rifaximin may decrease the exposure of concomitant CYP3A4 substrates administered (e.g. warfarin, antiepileptics, antiarrhythmics), due to the higher systemic exposure with respect to healthy subjects. An in vitro study suggested that rifaximin is a moderate substrate of P-glycoprotein (P-gp) and metabolized by CYP3A4. It is unknown whether concomitant drugs which inhibit P-gp and/or CYP3A4 can increase the systemic exposure of rifaximin. The potential for drug-drug interactions to occur at the level of transporter systems has been evaluated in vitro and these studies suggest that a clinical interaction between rifaximin and other compounds that undergo efflux via P-gp and other transport proteins is unlikely (MDR1, MRP2, MRP4, BCRP and BSEP).

Side effects. The most common adverse events with leflunomide treatment in clinical trials were gastrointestinal effects, pruritus, rash, hypertension, alopecia and liver enzyme elevations. Post-marketing, there have been rare reports of serious hepatic reactions and pancytopenia. See the SPC for more details on adverse events. Leflunomide does not have black triangle (▼) status. All serious suspected adverse reactions (even well recognised or causal link uncertain) should be reported to the MHRA. Drug interactions: Recent treatment with hepatotoxic or haematotoxic (eg.methotrexate) drugs may result in increased side effects; care should be taken when initiating leflunomide therapy. Switching to another DMARD after leflunomide treatment may raise the possibility of additive risks because of its long half-life. A washout period is required. Patients treated with leflunomide should not receive concomitant treatment with cholestyramine or activated powdered charcoal, because this leads to rapid and significant decreases in plasma leflunomide concentration.

Side effects. The most frequent and very common adverse reactions related to propafenone therapy are dizziness, cardiac conduction disorders and palpitations. Refer to SPC for full side-effect profile Propafenone does not have black triangle (▼) status. All serious suspected adverse reactions (even well recognised or causal link uncertain) should be reported to the MHRA.
