Q & A

Heavy and painful periods are common concerns of many women. The medical term for heavy bleeding is Menorrhagia. While painful periods are termed as dysmenorrhea. Menorrhagia does not allow you to follow your regular activities due to severe blood flow and cramps. Need of more than one sanitary pads for a few hours, extra protection during the night, bleeding longer than a week, blood clots larger than usual, anemia, tiredness, fatigue, etc. are some of the symptoms of menorrhagia. Although Menorrhagia is very common, many women do not experience severe blood loss.

Mefenamic Acid tablets are anti-fibrinolytic medicines. They reduce/stop heavy bleeding. Our body forms clots to stop bleeding. However, in some cases, these clots break down increasing the bleeding. Mefenamic Acid stops this clots from breaking down resulting in reduced bleeding. This is a short-term treatment.

Is having period pain normal?

YES. Many females experience levels of discomfort and pain during menstrual periods. For some, it is bearable, but some have severe pain and their day-to-day lives get affected with this.

How long do the pains normally last?

The pain can begin a day or two before your periods start. It can last for 2-4 days.

Will nonsteroidal anti-inflammatory medicines affect my stomach?

NO. But if you are a smoker or you consume caffeine, these drugs do have the potential to cause some irritation in your stomach. To avoid this as much as possible, you should take this medicine with milk and after a meal (with a full stomach).

Are there any risk factors associated with heavy menstrual bleeding (menorrhagia)?

YES. Anemia is one of the risks associated with menorrhagia or heavy menstrual bleeding. The blood loss reduces the number of circulating red blood cells (hemoglobin). Menorrhagia can also cause iron deficiency anemia.
