While above self-limiting or acute complaints are suitable for home treatment, also contact your healthcare provider during emergency situations or if symptoms worsen or fail to improve. Chronic or persistent complaints, which may or may not be mentioned above, require a different treatment and dosage protocol so are best managed by a qualified homeopath for good results.

Dosage Instructions (suitable for babies to adults)

For acute and self-limiting complaints, take one pill or five drops of the remedy every 15 minutes to 4 hours (15 minutes for intense symptoms, 4 hours for milder ones). Once an improvement is noticed, stop dosing and repeat the remedy only if symptoms return. If there is no improvement at all by three doses, choose a different remedy or seek professional guidance. Chronic symptoms or complaints require a course of professional treatment to manage the changes in potencies and remedies that will be required.
