Drug interactions not recommended

Although Nopal Cactus has only moderate interaction with other drugs, you should be always cautious with the combinations shown below:

  • Metformin (Glucophage): It is the most common drug taken as diabetes medications in its early stages and motivates the pancreas to produce insulin and lower blood glucose levels. However, the consumption of Nopal Cactus can lower the sugar levels a lot more than usual. Consider lowering the dose of metformin when taking Nopal Cactus.
  • Mainstream antidiabetic drugs (insulin-like drugs): People who are diagnosed with diabetes mellitus usually take glimepiride (Amaryl), insulin, pioglitazone (Actos), rosiglitazone (Avandia), glipizide (Glucotrol), tolbutamide (Orinase). Try to avoid consuming prickly pear supplements when these drugs are prescribed to you.
  • Warfarin anticoagulant agents (Coumadin, Jantoven, Apo-warfarin): Should you take these drugs to prevent blood clotting then it would be better to minimize your exposure to cactus opuntia supplements and raw fruits, since you may experience unprecedented bleeding episodes.

Apart from these drugs, there are no other known interactions of Nopal Cactus extracts with other agents and in most cases, their consumption is safe and healthy for you.
