Hi,
Double dose of Marvelon can not be an effective alternative to Plan-B. Marvelon is a
combined oral contraceptive pill is commonly used a regular birth control pill to prevent and unwanted pregnancy. Each pill of Marvelon contains two types
female sex hormones oestrogen (0.03 mg) and progestogen 0.15 mg. Whereas the Plan-B (
emergency contraceptive pill) contains 1.5 mg of progestogen which is commonly used within 72 hours after unprotected sex.
So, if you want to use Marvelon as an effective alternative to Plan-B, you need to take multiple pills of Marvelon to approximate the 1.5 mg of Progesterone found in Plan-B. This amounts to overdose of hormones which can cause
severe vomiting, breast tenderness, abdominal cramps, headache, tiredness and abnormal/
irregular vaginal bleeding. Hence, it is not advisable to take extra doses of Marvelon as an alternative to Plan-B.
Hope I have answered your query. Let me know if I can assist you further.
