Since ivermectin is usually taken as a one-time dose, missing a dose is uncommon. If your doctor prescribed multiple doses and you forgot one, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed one and do not double up.
Buy only from registered pharmacies and avoid roadside sellers or unverified online stores, as fake ivermectin tablets are common in Nigeria. Do not use ivermectin meant for animals (veterinary ivermectin) on yourself, as the concentration is different and dangerous. If you live in areas where Loa loa (African eye worm) is common, make sure your doctor tests you before prescribing ivermectin.
Avoid taking ivermectin with warfarin (blood thinner) as it may increase the risk of bleeding. Be cautious if you are also taking drugs for seizures or epilepsy like carbamazepine, as they may reduce ivermectin's effectiveness. Avoid drinking alcohol around the time you take ivermectin as it may increase dizziness and side effects.
