STROMECTOL

Active ingredient: Ivermectin


Consumer Medicine Information (CMI)

This leaflet provides important information about using STROMECTOL.

You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using STROMECTOL.

Where to find information in this leaflet:

1. Why am I using STROMECTOL?

STROMECTOL contains the active ingredient Ivermectin. Ivermectin is derived from a class of antiparasitic agents called avermectins.

STROMECTOL is used to treat river blindness (onchocerciasis) and threadworm involving the intestines (intestinal strongyloidiasis). These are caused by worm infections. In onchocerciasis the worm infection mainly affects the skin, glands (lymph nodes) and eyes. Changes to the skin may include an itchy rash, pale or dark patches, nodules (small lumps under the skin), thickening of the skin and/or loss of elasticity. The infection can cause enlarged glands in the neck, armpits or groin. The infection can also affect the eye and may cause conjunctivitis, a gritty or painful eye and may lead to blindness.

In the form of strongyloidiasis that is treated with STROMECTOL, the worm infection mainly affects the intestines and skin. Symptoms which may occur include itchy rash, vomiting, diarrhoea and stomach pain.

STROMECTOL works by killing the developing worms.

STROMECTOL is also used to treat scabies which is caused by the Sarcoptes scabiei mite.

Infection with the scabies mite causes discomfort and often intense itching of the skin, particularly at night, with irritating blisters or lumps on the skin. Classical sites of infestation are between the fingers, the wrists, underarm areas, female breasts (particularly the skin of the nipples), stomach area, penis, scrotum, and buttocks. Infants are usually affected on the face, scalp, palms and soles.

Scabies is usually spread person to person via direct skin contact, including sexual contact, though transfer via objects such as clothing or furnishings is also possible. Each person in contact with the infected person should seek treatment immediately. Note that the blisters or lumps on your skin may not go way immediately.

Bed linen and clothing should be washed in hot water, no bleaching is required. Shoes and other non washable items should be placed in a tightly sealed plastic bag for at least 3 days.

There are 2 types of scabies: typical scabies and crusted scabies (more severe).

Your doctor may have prescribed STROMECTOL for another reason. Ask your doctor if you have any questions about why STROMECTOL has been prescribed for you.
