WHY is this medicine prescribed?

Ivermectin is used to treat strongyloidiasis (threadworm; infection with a type of roundworm that enters the body through the skin, moves through the airways and lives in the intestines). Ivermectin is also used to control onchocerciasis (river blindness; infection with a type of roundworm that may cause rash, bumps under the skin, and vision problems including vision loss or blindness). Ivermectin is in a class of medications called anthelmintics. It treats strongyloidosis by killing the worms in the intestines. It treats onchocerciasis by killing the developing worms. Ivermectin does not kill the adult worms that cause onchocerciasis and therefore it will not cure this type of infection.

HOW should this medicine be used?

Ivermectin comes as a tablet to take by mouth. It is usually taken as a single dose on an empty stomach with water. If you are taking ivermectin to treat onchocerciasis, additional doses 3, 6, or 12 months later may be necessary to control your infection. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ivermectin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are taking ivermectin to treat strongyloidiasis, you will need to have a stool exam at least three times during the first 3 months after your treatment to see if your infection has cleared. If your infection has not cleared, your doctor will probably prescribe additional doses of ivermectin.

Are there OTHER USES for this medicine?

Ivermectin is also sometimes used to treat certain other roundworm infections, head or pubic lice infestation, and scabies (itchy skin condition caused by infestation with small mites that live under the skin). Talk to your doctor about the risks of using this medication for your condition.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

ask your doctor about the safe use of alcoholic beverages while you are taking ivermectin.
if you are taking ivermectin for onchocerciasis, you should know that you may experience dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.if you are taking ivermectin for strongyloidiasis and have had loiasis (Loa loa infection with a type of worm that causes skin and eye problems) or if you have ever lived in or traveled to areas of West or Central Africa where loiasis is common, you should know that you may have a serious reaction. Call your doctor immediately if you experience blurred vision, head or neck pain, seizures or difficulty walking or standing.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.http://www.upandaway.org
