Patients should stop taking methadone and contact a doctor or emergency services right away if they: 1  Experience difficulty breathing or shallow breathing. 2  Feel lightheaded or faint. 3  Experience hives or a rash; swelling of the face, lips, tongue, or throat.

It makes sense. The card with the highest interest rate is usually the one that will cause you the most financial pain. The national average interest rate on a credit card is 15.2 percent, so if you bought a $1,000 refrigerator with a credit card, you'd pay a lot in interest if you took your time paying it off.
These days, most credit cards compound interest on a daily basis, not monthly. For example, letâs say you have a revolving balance of $10,000 on your credit card, and your daily interest rate is 0.041% (which is approximately equivalent to an APR of 15%).
