Interactions between substances are often difficult to predict reliably. Individual factors (e.g., pre-existing conditions, medications, dosage, purity/contaminants, method of consumption) can significantly alter risks and interactions. Combining drugs is therefore generally not recommended, as it usually increases the risks of substance use.

Although considerable effort has been made to avoid errors or misleading information, with the very large number of possible combinations, some content may not be completely correct or up-to-date. Where no scientific sources are cited, information may be based solely on users' experiences. SaferMix should not be used as your sole source of information, but is intended as a supplementary quick reference that makes no claim to completeness.

In acute emergencies, emergency services should be contacted at 112 for immediate on-site medical assistance and/or the responsible poison control center for telemedical advice regarding substance interactions.
