Osmotic laxatives (lactulose, PEG): draw water into the bowel
Stimulant laxatives (senna, bisacodyl): short-term only
Common over-the-counter options

Lactulose, polyethylene glycol (PEG) — osmotic
Senna, bisacodyl — stimulant (short-term)

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 laxative for constipation?
Fibre and osmotic laxatives (like ispaghula, lactulose or PEG) are gentle and suit regular use; stimulant laxatives (senna, bisacodyl) work faster but are for short-term use.
Are laxatives safe for daily use?
Gentle fibre and osmotic laxatives can be used longer term under guidance; stimulant laxatives are best short-term. Diet and fluids should come first.
When should constipation be checked?
With severe pain and vomiting, blood in the stool, weight loss, or a new change in bowel habit — especially over 50.
