IVERMECTIN – ORAL
COMMON BRAND NAME(S): Stromectol
USES: This medication is used to treat certain parasitic roundworm infections. Curing parasitic infections helps to improve your quality of life. In people with weakened defence (immune) systems, curing roundworm infections can reduce the risk of developing a severe or life-threatening infection. Ivermectin belongs to a class of drugs known as anthelmintics. It works by paralyzing and killing parasites.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. This drug may also be used for other parasitic infections, including lice and scabies.
HOW TO USE: Take this medication by mouth with a full glass of water (8 ounces or 240 millilitres) on an empty stomach at least 1 hour before a meal. Ivermectin is usually taken as a single dose or series of doses, or as directed by your doctor. Dosage is based on your weight, medical condition, and response to treatment. Tell your doctor if your condition persists or worsens.
SIDE EFFECTS: Headache, dizziness, muscle pain, nausea, or diarrhea may occur. If you are being treated for “river blindness” (onchocerciasis), you may experience reactions to the dying parasites during the first 4 days of treatment, including joint pain, tender/swollen lymph nodes, eye swelling/redness/pain, weakness, vision changes, itching, rash, and fever. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To reduce dizziness upon standing, get up slowly when rising from a sitting or lying position. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if any of these rare but very serious side effects occur: neck/back pain, swelling face/arms/hands/feet, chest pain, fast heartbeat, confusion, seizures, loss of consciousness. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Before using this medication, tell your doctor or primary health care provider your medical history, especially of: liver problems. If you have traveled or lived in West or Central Africa, you may be infected with certain parasites (such as Loa loa, African trypanosomiasis) that could cause problems with ivermectin treatment.
