  • Naproxen sodium, such as Anaprox.

Other medicines can cause abdominal cramping, diarrhea, or constipation. Medicines that may cause these symptoms include:

• Antidiarrheals, which can cause constipation and abdominal cramping.
• Laxatives, which can cause diarrhea and abdominal cramping.
• Antibiotics, such as ampicillin, amoxicillin, tetracycline, cefuroxime, erythromycin, and clindamycin, which can cause abdominal cramping and burning pain.
