Hallow Dear,
You seem to be from Philippines. Althea is mainly available in Philippines. These pills contain
Cyproterone which is a progestational agent, and
Ethinylestradiol which is an Oestrogen product. Both these medicines cause nausea, sometimes vomiting and pain in abdomen due to the fact that they increase acidity in the stomach and secondly due to the fact that they are detoxicated in the Liver.
From your history, it seems you are not consuming these pills after dinner. Please change the timings of these pills to post dinner time. On full stomach, the
gastritis effect is much minimized. Stick to one specific time for consumption of these pills. Moreover, you may take some
proton pump inhibitors like
Pantoprazole every morning on empty stomach which will help you control the gastritis. All the gastro-enteric symptoms you are experiencing are known with the birth control pills due to hormones in them. Usually they stop after a month or so; however if they continue, you may try Pantoprazole. If still they persist, you may change the brand with the help of your Gynaecologist.
The brownish discharge you had is known as
breakthrough bleeding which is a hormonal effect. If it continues, you may take two pills on that day which will stop the bleeding.
Yes, putting on weight is a known (side) effect of birth control pills. It is due to water retention as well as fat deposition. You may try to control it by restriction on salt intake and consuming high protein, low fat and low
carbohydrate diet.
I am sure this would help you.
Dr. Nishikant Shrotri
