INQUIRE ABOUT Dronis P Tablet (Drospirenone)
What is Dronis P Tablet? Dronis P is a prescription contraceptive tablet.
Each active tablet contains Dronis 30 mg of drospirenone.
Drospirenone is a progestogen derived from spironolactone.
The tablet contains no oestrogen at all.
That makes it a progestogen-only pill.
It is marketed in India by Sun Pharmaceutical Industries Ltd.
It is sold as a strip of 24 tablets.
Preventing pregnancy in women of reproductive age.
That is the only licensed use in the labels consulted.
Who an oestrogen-free pill can suit:
Women who cannot take oestrogen for health reasons.
Women who prefer to avoid oestrogen.
Women who are breastfeeding, per UK guidance.
Smokers over the age of 35, per the same guidance.
It gives no protection against sexually transmitted infections.
It is not an emergency contraceptive.
How Dronis P Works (Mechanism of Action) The action happens in four simple steps:
Dronis 20 mg suppresses the hormone signals that mature an egg.
It prevents the surge that normally releases that egg.
So ovulation is reliably stopped across the cycle.
It also thickens the mucus at the cervix.
Two listings say it works by preventing fertilisation of the egg.
One says it works by preventing implantation in the womb.
The approved labels describe ovulation suppression as the main action.
In other words, no egg is released in the first place.
This page follows the approved labels.
What makes drospirenone distinctive:
It is chemically related to spironolactone, a water tablet.
It has mild anti-mineralocorticoid activity.
That can raise the potassium level in the blood.
It also has anti-androgenic properties.
It has no oestrogen-like or steroid-like activity.
Dosage Guide The regimen below comes from approved drospirenone 4 mg labelling.

The 24-hour window explained:
Most progestogen-only pills allow only a 3 or 12 hour delay.
Drospirenone 4 mg allows a 24-hour window in its labelling.
That is one of its main practical advantages.
It still works best taken at the same time daily.
UK guidance notes these rules differ from other mini-pills.
Do not copy starting advice from another progestogen-only pill.
Follow the instructions supplied with your own pack.
How to Take Dronis P Take one tablet every day at about the same time.
Aim for exactly 24 hours between tablets.
Swallow the tablet whole with water.
Follow the order printed on the blister.
Take the inactive tablets too, so the habit continues.
Start the next pack the day after finishing one.
Never leave a gap between packs.
Use condoms as well if you may be at risk of infection.
Within 3 to 4 hours of a tablet, absorption may be incomplete.
Take the next day’s tablet as soon as you can.
Take it within 12 hours of your usual time if possible.
Otherwise follow the missed-tablet advice on your pack.
