When using more than one medication, there may be a situation of drug interaction, which is also true in the case of medical Cannabis. It is recommended to consult with your treating physician prior to starting treatment with Cannabis, and to examine whether there are reciprocal reactions that can be expected between the Cannabis and the medication taken by the patient. Also, during the treatment with Cannabis it is important to monitor the patient’s condition regularly and to ensure that the drug treatment remains balanced even with the use of Cannabis.
