You will have to take the pill on day one of your menstrual cycle and continue taking it for a whole month. Once the pack gets over, start with a new one. If you experience vomiting within 4 hours of dose intake, take another tablet. In case you missed your dose and you are late by 12 hours in taking the missed dose, use a condom during intercourse for a period of 2 days. If you experience stomach upset, then start taking it with food in the evening or at bedtime.

Headache, breast pain, nausea, and acne are some commonly seen side effects of this medicine. If these bother you or appear serious, let your doctor know. There may be ways of reducing or preventing them. You might experience spotting or bleeding between menstrual periods or missed periods. Consult with your doctor if this occurs frequently or persists longer. It might increase your blood pressure, monitor your blood pressure regularly.

Before taking this medicine, let your doctor know if you smoke and are over 35, or if you have ever had a heart attack or have cancer of uterus/cervix, or vagina. Your doctor should also know about all other medicines you are taking as many of these may make this medicine less effective or change the way it works. Do not take the medicine if you are pregnant already or breastfeeding.

Uses of Deereg Tablet

Benefits of Deereg Tablet

Contraception
Deereg Tablet is a contraceptive medicine that stops you from getting pregnant in multiple ways. Firstly, it prevents an egg from being released from your ovaries. Secondly, it makes the fluid (mucus) in your cervix thicker, which makes it more difficult for sperm to enter the womb. Deereg Tablet is a reliable and safe method for contraception, if used correctly. It does not interrupt with sex and you can lead a normal routine life without any worries. Take it as directed by the doctor to get the most benefit.

How to use Deereg Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Deereg Tablet may be taken with or without food.

How Deereg Tablet works

Deereg Tablet is a combination of two medicines. Ethinyl Estradiol and Dienogest are two synthetic hormones that inhibit ovulation (release of an egg from an ovary) in women to prevent unintended pregnancy. It also protects the sperms from entering into the uterus (womb) by changing the mucus consistency of the vagina and cervix (passage to the womb).

Quick tips

  • Take Deereg Tablet at the same time daily without skipping, even if you are not sexually active, to keep hormones stable.
  • If you miss a dose, take it as soon as you remember. But if it is more than 12 hours late, use backup protection.
  • You may experience spotting or irregular periods in the first few months. This is common and usually settles.
  • Avoid smoking while on Deereg Tablet, especially if you are over 35, as it increases the risk of serious side effects.
  • Keep a small calendar or pill tracker to ensure you follow the 28-day cycle correctly without confusion.
