Hi, Easy Lax Plus is a medication that contains bisacodyl, which is used to treat constipation. Some of the common side effects of Easy Lax Plus are abdominal cramps, nausea, diarrhea, electrolyte imbalance, and dehydration. The sensation of feeling the medication stuck in the lower esophagus and difficulty breathing when taking deep breaths may be due to irritation or inflammation caused by the medication. It is recommended to drink the medication with plenty of water to help it pass through the esophagus and into the stomach. You should avoid taking the medication with small amounts of water, as it may not be enough to help it move through the esophagus properly. If you continue to experience difficulty breathing or pain when taking deep breaths, you should seek medical attention immediately. This may indicate a more serious condition that requires medical attention. Additionally, it is important to speak with your doctor before taking any new medications, especially if you have any underlying medical conditions or are taking any other medications. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
