Heavy periods: what helps and when to see a doctor

Practical ways to cope with heavy bleeding, and the treatments a doctor can offer.

What research and doctors say

Ask a doctor

Know what "heavy" means

Needing to change a pad or tampon every 1–2 hours, passing clots bigger than a coin, bleeding through to clothes or bedding, or periods lasting more than 7 days — these are worth seeing a doctor about.

Ask about tranexamic acid or the hormonal coil

A doctor can prescribe medicines that reduce bleeding a lot, such as tranexamic acid tablets taken only on period days, or a hormonal IUD.

Practical tip

Watch your iron

Heavy periods can cause anaemia, which makes you tired and breathless. Eat iron-rich foods and ask for a blood test if you're exhausted.

Practical tip

Period pants under a cup or tampon

Many women use a menstrual cup or tampon with period pants as back-up on the heaviest days, especially at night.
