This medication has rarely caused a very serious lack of blood flow to the hands and feet (peripheral ischemia) or to the brain, which could cause a stroke. The risk is increased when this medication is taken with other drugs that can affect the removal of ergotamine from your body. Examples include azole antifungals (such as ketoconazole, itraconazole), macrolide antibiotics (such as clarithromycin, erythromycin, troleandomycin), HIV protease inhibitors (such as ritonavir, nelfinavir, indinavir), among others. See also Drug Interactions section.Who should not take Cafetrate rectal?
This combination medication is used to treat or prevent a certain type of headache (vascular headaches such as migraine headaches and cluster headaches). Ergotamine helps narrow widened blood vessels in the head, which reduces the throbbing effects of vascular headaches. Caffeine increases the effects of ergotamine by also narrowing the widened blood vessels in the head.
The suppository form is used when medications cannot be taken by mouth (e.g., due to nausea and vomiting).
Unwrap and insert one suppository rectally as directed by your doctor. Remain lying down for a few minutes, and avoid having a bowel movement for an hour or longer so the drug will be absorbed. The suppository is for rectal use only.
If the suppository is exposed to heat and softens, chill in ice-cold water before unwrapping and using the suppository.
Dosage is based on your medical condition and response to therapy. This medication works best if it is used as the first signs of the headache occur. If you wait until the headache has worsened, the medication may not work as well.
This medication usually should be used only as needed. It is not meant for long-term daily use. The maximum dose is 2 suppositories for a single headache attack and 5 suppositories in any 7-day period.
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time (more than a few weeks) or in high doses. In such cases, rebound headaches may occur if you suddenly stop using this medication. This headache may be different from your original headache and may last a few days. Report any such headaches to your doctor immediately. Consult your doctor or pharmacist for more details.
Inform your doctor if you notice increased use of this medication, the medication not working as well, a worsening of headaches, an increase in the number of headaches, or use of this medication for more than 2 headache episodes a week. Your doctor may need to change your medication and/or add a separate medication to prevent the headaches.
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.
