Hi,
Althea pill contains both cyproterone acetate and
ethinyl estradiol which is used in the prevention of unwanted pregnancies from unprotected sexual intercourses and in the treatment of acne as well as hirsutism. But like other medications this medication has some side effects of its own. Again, taking this medication too frequently, also may aggravate side effects.
It may cause nausea, vomiting, headache, breast tenderness and enlargement, mood swings, changes in appetite, spotting or breakthrough
bleeding between periods, vaginal bleeding,
vaginal discharge and many more. Usually these side effects are mild as well as self limiting and go away over time as the body adjusts to this medication.
But if any of these side effects persist for long or bother you then you should consult your doctor first for
medical help. Without knowing the date of your last menstrual period, it is difficult to predict whether you will become pregnant or not. If you have any doubt, then you can undergo urine test for pregnancy 7 days after the last missed period.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General And Family Physician
