Cerave Itch Relief (pramoxine HCl)

For self-medication for the temporary relief of pain and itching associated with lip or skin irritations in adults and children 2 years of age and older, pramoxine hydrochloride 1% gel, lotion, ointment, or solution is applied topically to the affected area up to 3 or 4 times daily. For use in children younger than 2 years of age, a pediatrician should be consulted.

For self-medication for the temporary relief of pain, soreness, burning, itching, or discomfort caused by hemorrhoids or other anorectal disorders in adults and children 12 years of age and older, pramoxine hydrochloride 1% aerosol foam, cream, ointment, or pledget is applied topically to the affected area up to 4 or 5 times daily or after each bowel movement. The manufacturers state that this dosage should not be exceeded unless directed by a clinician. For use in children younger than 12 years of age, a clinician should be consulted.

For self-medication for the management of anogenital pruritus, pramoxine hydrochloride 1% pledget is applied to the external vaginal area up to 3-4 times daily. For use in children younger than 12 years of age, a clinician should be consulted.

Preparations containing pramoxine hydrochloride are applied topically. These preparations may be applied to the lip in the form of an ointment (''lip balm''); to the skin in the form of a gel, lotion, ointment, or solution; to the external vaginal area in the form of pledgets (pads); or to the external anorectal area in the form of an aerosol foam, cream, ointment, or pledgets.

The lotion containing pramoxine hydrochloride should be shaken well prior to use. The aerosol foam should be shaken well and dispersed onto a clean tissue before applying to the affected area. Pledgets should be applied gently by patting or wiping the affected area; pledgets should be used only once and then discarded.

Patients receiving pramoxine-containing preparations for the management of hemorrhoids or other anorectal disorders should be advised to cleanse the affected perianal area with mild soap and warm water and rinsing thoroughly whenever practical; the area then should be dried by patting or blotting with toilet tissue or a soft cloth before application of the drug.

Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

Local Anesthetics/Long-Acting Bupivacaine

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Concurrent use of other local anesthetics or use of other local anesthetics within 96 hours following long-acting bupivacaine may result in additive neurologic and cardiovascular effects. Use of articaine, benzocaine, bupivacaine, lidocaine, mepivacaine, prilocaine, procaine, ropivacaine, and tetracaine may also increase the risk of methemoglobinemia.(1,2) Non-liposomal bupivacaine may impact the pharmacokinetic and/or physicochemical properties of the liposomal formulation when administered in the same syringe or used simultaneously unless the ratio of mg of non-liposomal bupivacaine to mg of bupivacaine liposomal does not exceed 1:2.(1) Local anesthetics other than bupivacaine may trigger the immediate release of bupivacaine from the liposomal formulation when administered together locally.(1)

CLINICAL EFFECTS: Concurrent or use of local anesthetics with 96 hours of use of long-acting bupivacaine may result in neurologic and cardiovascular toxicity. Use of articaine, benzocaine, bupivacaine, lidocaine, mepivacaine, prilocaine, procaine, ropivacaine, and tetracaine may also result in methemoglobinemia.(1,2) Non-liposomal bupivacaine may impact the pharmacokinetic and/or physicochemical properties of the liposomal formulation when administered in the same syringe or used simultaneously unless the ratio of mg of non-liposomal bupivacaine to mg of bupivacaine liposomal does not exceed 1:2.(1) Local anesthetics other than bupivacaine may trigger the immediate release of bupivacaine from the liposomal formulation when administered together locally.(1)

PREDISPOSING FACTORS: Use of additional agents that are associated with methemoglobinemia may further increase the risk of methemoglobinemia.(1) Patients who are at increased risk of developing methemoglobinemia include those with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, infants under 6 months of age, and concurrent exposure to oxidizing agents or their metabolites are more susceptible to developing clinical manifestations of the condition. If local anesthetics must be used in these patients, close monitoring for symptoms and signs of methemoglobinemia is recommended.(1)

PATIENT MANAGEMENT: Avoid the use of other local anesthetics within 96 hours following the administration of long-acting bupivacaine. In patients for whom use is required, monitor for neurologic and cardiovascular effects. Also monitor for methemoglobinemia with use of articaine, benzocaine, bupivacaine, lidocaine, mepivacaine, prilocaine, procaine, ropivacaine, and tetracaine.(1,2) Non-liposomal bupivacaine may be administered in the same syringe as bupivacaine liposomal or injected immediately before bupivacaine liposomal as long as the ratio of mg of non-liposomal bupivacaine to mg of bupivacaine liposomal does not exceed 1:2.(1) Lidocaine may be administered 20 minutes or more prior to bupivacaine. It is unknown if other local anesthetics may be used without compromising the release characteristic of bupivacaine liposomal.(1)

DISCUSSION: Concurrent use of other local anesthetics or use of other local anesthetics within 96 hours following long-acting bupivacaine may result in additive neurologic and cardiovascular effects. Use of articaine, benzocaine, bupivacaine, lidocaine, mepivacaine, prilocaine, procaine, ropivacaine, and tetracaine may also increase the risk of methemoglobinemia.(1,2) Non-liposome bupivacaine may impact the pharmacokinetic and/or physicochemical properties of the liposomal formulation when administered in the same syringe or used simultaneously unless the ratio of mg of non-liposomal bupivacaine to mg of bupivacaine liposomal does not exceed 1:2.(1) Local anesthetics other than bupivacaine may trigger the immediate release of bupivacaine from the liposomal formulation when administered together locally. Lidocaine may be administered 20 minutes or more prior to bupivacaine. It is unknown if other local anesthetics may be used without compromising the release characteristic of bupivacaine liposomal.(1)
