Hvis behandlingen afbrydes i mere end nogle dage, må behandlingen genoptages med 1, 5 mg 2 gange daglig for at formindske muligheden for bivirkninger (f. eks. opkastninger).
If treatment is interrupted for more than several days, it should be re-initiated at 1.5 mg twice daily to reduce the possibility of adverse reactions (e. g. vomiting).
