I am personally quite lenient and will say to take your remedy. If it is effective and then you drink coffee and you are feeling worse, then this may indicate an interaction. See what happens when you stop drinking coffee and take your remedy again. It’s every individual and each person has different sensitivities. I think it is better to stay away just in case. Possibly it does antidote the effectiveness of a remedy not on an energetic level but by harming the body’s ability to heal. In our practice I have seen the patients who takes coffee and who does not takes coffee the effect of the medicine is same.

   Dr. J. H. Clarke writes in his Clinical Repertory –Part 4 i.e. Clinical Relationships of Coffea cruda—this remedy antidotes following remedies. Amb,Am-m, Ana, Ang, Aur, Bei, Bor, Carb v, Caust, Cham, Cic, Cal, Con, Cyc, Gam, Gels, Glo, Hy-x, Ign,Iod, K ca, Lach, Lau, Lyc, Man, Mos, Nux Par Ph x, Phos, Puls, Rhs, Sty, Tab and Val.

   This clearly shows that Coffea cruda antidotes above mentioned homoeopathic medicines and not all homoeopathic medicines. Hence, my opinion is “Generalizing the term as Coffee antidotes homoeopathic medicines are not realistic.

   Even though coffee don’t antidote any homoeopathic medicines , I advise patient not to take any Homoeopathic Medicines before tea, coffee, or any strong smelling food or any liquid. I advise them to take on clean tongue. I have seen many patients strictly follow the instructions, but however I have seen with good improvement even in disobedient patients. My inference is if correct similimum is prescribed, it will not antidote.
