Rectal suppositories are a dosage form which contains medication intended to be inserted into the rectum to deliver the medication directly to that area, or throughout the body. They can come in different shapes or sizes and most commonly have a narrow end on one side. The suppository melts once placed inside the body where the medication is then absorbed. Medications placed into a rectal suppository form may include laxatives, drugs to treat hemorrhoids, and are often used when someone is unable to take a medication by mouth. For instance, if the patient is vomiting or is experiencing seizures, during which a patient isn’t able to take medication by mouth. Talk with your doctor or pharmacist to see if compounded rectal suppositories are the right choice for you.
