What drugs interfere with the reabsorption of contraceptive steroid?

Aspirin and Ibuprofen
Acetaminophen and Hydrocodone
Penicillin V and Tetracycline
Metformin and Simvastatin

The correct answer is: Penicillin V and Tetracycline

The correct answer is C, Penicillin V and Tetracycline. Penicillin V and Tetracycline are both antibiotics, meaning they can interfere with the effectiveness of contraceptive steroids. Antibiotics can alter the balance of bacteria in the gut, which in turn can change how estrogen and progesterone are metabolized by the body. This can lead to lower levels of these hormones in the blood, reducing the effectiveness of contraception. Aspirin and Ibuprofen (A) are pain relievers and do not interfere with contraceptive steroids. Acetaminophen and Hydrocodone (B) are also pain relievers and do not interact with contraceptive hormones. Metformin and Simvastatin (D) are commonly used for diabetes and high cholesterol respectively, and do not have any known interactions with contraceptive steroids.
