Are there any other precautions or warnings for PMS-Gabapentin?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Alcohol: Avoid alcohol while taking gabapentin, as gabapentin may cause alcohol intolerance that leads to an unpleasant reaction after drinking alcohol, such as flushing, redness of the face after drinking alcohol, nausea, palpitations, or headache.

Drowsiness/reduced alertness: If you have uncontrolled epilepsy, do not drive or handle potentially dangerous machinery. Gabapentin may cause drowsiness, dizziness, or problems with coordination. Avoid any activity requiring mental alertness or physical coordination until you determine that gabapentin does not affect you in this way.

Kidney function: Gabapentin is not removed from the body as quickly in people with reduced kidney function as compared with those who have regular kidney function. Your doctor may reduce your dose as needed.

Stopping the medication: As with other medications used to control seizures, stopping gabapentin suddenly could increase the risk of seizures. Do not stop gabapentin suddenly. Ask your doctor how to safely and gradually stop the medication.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking gabapentin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children.

What other drugs could interact with PMS-Gabapentin?

There may be an interaction between gabapentin and any of the following:

  • antacids containing magnesium or aluminum
  • cimetidine
  • hydrocodone
  • morphine

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
