• Antacids containing aluminum or magnesium: may reduce gabapentin absorption if taken together. Leave at least two hours between doses.
• Opioid analgesics such as morphine: combined use can increase drowsiness coupled with the risk of respiratory depression.
• Phosphate binders like sevelamer: may lower gabapentin levels due to reduced absorption.
• Some non-steroidal anti-inflammatory drugs: may alter gabapentin pharmacokinetics slightly.
• Alcohol content by volume, benzodiazepines, sleeping tablets and other sedatives: increase the risk of dizziness, drowsiness and breathing problems.

This list is not comprehensive. Always give your clinician a complete list of prescription drugs, over-the-counter remedies, supplements and recreational substances you use.

Alternative medicines and analogous drugs

Treatment choices depend on the condition being treated, patient characteristics and previous response to medicines. Some spare options commonly considered in the UK include:

• Pregabalin (for example Lyrica): similar action to gabapentin; tends to allow faster dose escalation but may cause dizziness in some patients.
• Amitriptyline: a tricyclic antidepressant often used for chronic nerve pain; sedative effects can be helpful at night.
• Duloxetine treatment: an SNRI antidepressant useful in some forms of neuropathic pain.
• Carbamazepine: used for trigeminal neuralgia and certain seizure types; has significant mutual interaction potential.
• Other antiepileptics such as lamotrigine, valproate and topiramate: choice depends on seizure type, age, pregnancy plans and comorbidities.

Discuss the relative benefits, likely residual effects and intercommunication profiles of these options with your prescriber involved. For cost information, consult the pricing details. Costs in the United Kingdom.
