Your doctor will prescribe a medication to help you pass the tapeworm. Carefully follow your doctor's instructions for how to take your medication. The most common medications prescribed to treat a tapeworm infection include:  Praziquantel (Biltricide). This medication works by killing certain worms. Do not take this medication if you are pregnant or breastfeeding, allergic to any ingredient in the medication, have a worm infection in your eye, or if you are on rifampin.  Albendazole (Albenza). This medication prevents newly hatched worms from growing in your body. It treats specific types of tapeworm infections, including those you get from eating pork and from being around infected dogs.  Nitazoxanide (Alinia). This medication is mainly used to treat parasites that you pick up from swimming in a lake or spending time in other moist places. If you have to pass a large tapeworm, it is likely that you will have some pain and cramping. This is normal, but make sure that you call your doctor if the pain becomes severe. To ensure that you are tapeworm free, your doctor will need to check your stools again one month following your treatment and then again three months after your treatment. Make sure that you keep this appointment even if you are feeling fine.
