Antrolin is a rectal cream that contains nifedipine with a relaxing effect on soft peripheral muscles such as the anal sphincters.
The action of nifedipine is increased by lidocaine, with local anesthetic effect and pain reliever.

Indications:
– Treatment of hemorrhoids.
– Treatment of anal fissures.
– Treatment of other proctological diseases associated with anal sphincter hypertrophy.

Do not use Antrolin if:
– you are allergic to any of the ingredients present in the formulation.
– you are pregnant or breastfeeding.
– you suffer from a severe form of hypotension or cardiovascular insufficiency.

Pregnancy and breastfeeding
Nifedipine and lidocaine cross the placental barrier and are excreted in breast milk. Studies in mice and rabbits have shown that nifedipine can provoke teratogenic effects. Lidocaine has not been shown to pose a risk to the fetus. Antrolin should not be used during pregnancy and lactation.

Possible side effects
Side effects such as pain, burning sensation, itching, hyperemia, and bleeding may occur locally.
Such effects decrease when treatment is discontinued.
In very rare cases, allergic reactions happened mainly due to the presence of lidocaine.

This is an OTC medicine, so it can be taken without a doctor’s recommendation.
Before using this medicine carefully read the package leaflet as it contains more detailed information.
Consult your doctor or pharmacist for any doubt.
