multicheck MultiCheck Results - 4 Interactions

Smiley face Smiley face

Avoid/Use Alternative

Smiley face Smiley face Cheratussin AC (codeine/ guaifenesin) + Topamax (topiramate)

Avoid/Use Alternative


codeine + topiramate

avoid combo if antitussive use; otherwise, use alternative or monitor withdrawal sx, respiratory rate; decr. dose of one or both drugs, use lowest effective doses and shortest duration of concomitant tx: combo with topiramate doses >200 mg/day may decr. codeine and active metabolite morphine levels, efficacy; may incr. risk of profound CNS and respiratory depression, psychomotor impairment; may alter seizure control (hepatic metabolism induced, may decr. production of active metabolite morphine; additive effects; antagonistic effects, codeine may decr. seizure threshold)

Smiley face Smiley face Cheratussin AC (codeine/ guaifenesin) + Vasculera (diosmiplex)

Avoid/Use Alternative


codeine + diosmin

use alternative or monitor respiratory rate, consider decr. codeine dose: combo may incr. codeine and active metabolite morphine levels, risk of CNS and respiratory depression, psychomotor impairment, other adverse effects (hepatic metabolism inhibited, may incr. production of active metabolite morphine)

Monitor/Modify Tx

Smiley face Smiley face Cambia (diclofenac potassium) + EstroGel (estradiol transdermal)

Monitor/Modify Tx


diclofenac + estradiol (hormone replacement)

monitor thrombosis s/sx; use lowest effective diclofenac dose, shortest effective tx duration: combo may incr. risk of thromboembolism (additive effects)

Smiley face Smiley face Cambia (diclofenac potassium) + Vasculera (diosmiplex)

Monitor/Modify Tx


diclofenac + diosmin

monitor bleeding s/sx; use lowest effective diclofenac dose, shortest duration of concomitant tx: combo may incr. diclofenac levels, risk of GI or other bleeding (including life-threatening), other adverse effects (hepatic metabolism inhibited, additive effects)

Additional Considerations

Smiley face Smiley face topiramate in Topamax

beverages or products containing ethanol are contraindicated within 6h of topiramate extended-release (ER) capsules administration; combo may incr. topiramate release rate, levels, risk of adverse effects, decr. duration of efficacy

Smiley face Smiley face codeine in Cheratussin AC

consider prescribing an opioid overdose reversal agent, especially with concomitant CNS depressant use

add MAO inhibitor to Interaction Check if recent (14 days) use
