Avoid combining amitriptyline with MAO inhibitors. This combination can cause a dangerous increase in blood pressure, potentially leading to a serious medical emergency. Allow at least two weeks between stopping an MAO inhibitor and starting amitriptyline.
Alcohol and Other CNS Depressants
Mixing amitriptyline with alcohol or other central nervous system depressants, such as benzodiazepines (like diazepam or alprazolam) or opioids, significantly increases the risk of drowsiness, dizziness, and impaired coordination. This combination can be dangerous and should be strictly avoided.
Certain Medications
Some medications interact negatively with amitriptyline. These include some antihistamines (particularly those causing drowsiness), certain antipsychotics, and some blood pressure medications. Always inform your doctor or pharmacist of all medications, including over-the-counter drugs and supplements, you are taking before starting amitriptyline.
Grapefruit Juice
Grapefruit juice can interfere with the metabolism of amitriptyline, potentially increasing its levels in your blood. This can lead to side effects. Limit or avoid grapefruit juice while taking this medication.
Herbal Remedies and Supplements
Many herbal remedies and supplements can interact with medications. Discuss any herbal remedies or supplements with your doctor or pharmacist before taking them alongside amitriptyline. St. John’s Wort, in particular, is known to interact negatively with many antidepressants and should be avoided.
Always Consult Your Doctor
This information is not exhaustive. Always consult your doctor or pharmacist before starting or stopping any medication, including over-the-counter drugs, supplements, or herbal remedies, to ensure the safe and effective use of amitriptyline.
