The most important "medicine" for loose motion is ORS to prevent dehydration. Most cases are viral and settle on their own — anti-diarrhoeals and antibiotics are only for specific situations.
ORS is the mainstay — replaces lost fluids and salts
Zinc helps children recover faster
Continue eating bland food; keep breastfeeding
Most cases do NOT need antibiotics
Commonly used

Not a prescription. This lists medicines commonly used for this condition to help you understand your options — it is NOT a prescription. Do not self-medicate: the right choice and dose depend on the cause, your health and other medicines, and prescription drugs (especially antibiotics) need a doctor. Misusing antibiotics drives resistance.
Frequently asked questions
What is the best medicine for loose motion?
ORS to prevent dehydration is the key treatment, plus zinc for children. Most cases are viral and need no antibiotics; loperamide may help adults but not with blood or high fever.
Should I take antibiotics for loose motion?
Usually not — most diarrhoea is viral. Antibiotics are only for specific bacterial or parasitic infections diagnosed by a doctor.
Is loperamide safe?
For simple adult diarrhoea it can help, but avoid it if there is blood or high fever, and do not give it to young children.
