Can I take Diazepam and Tirzepatide together?

Why this happens

Tirzepatide is a GLP-1 and GIP receptor agonist that delays gastric emptying (the rate at which food and pills leave the stomach). This can delay the absorption (Tmax) of oral medications like diazepam. There is also a potential for additive central nervous system (CNS) depression.

What you should do

Be aware that your diazepam might take longer to work than usual. Do not take extra doses if you don't feel the effects immediately. Be extra cautious when driving or using machinery until you know how this combination affects your alertness. If you feel excessively sleepy or your anxiety/seizures are not well-controlled, speak to your doctor.

Important precautions

Alcohol consumption

You must not drink alcohol while taking diazepam. Combining them can cause dangerously shallow breathing, extreme sleepiness, and can be fatal.

History of pancreatitis or severe stomach issues

This medicine can cause severe inflammation of the pancreas (pancreatitis). Seek immediate medical help if you experience severe, persistent stomach pain that radiates to your back.

Long-term use and dependency

This medicine is for short-term use only (usually 2-4 weeks). Using it longer can lead to physical addiction and severe withdrawal symptoms if stopped suddenly.

Food and drink warnings

Alcohol

You must avoid drinking alcohol while taking diazepam. Alcohol increases the sedative effects of the medicine, which can lead to extreme sleepiness, dangerous breathing problems, and a risk of coma.

Grapefruit juice

Avoid drinking large amounts of grapefruit juice. Grapefruit can prevent your body from breaking down diazepam properly, leading to higher levels of the medicine in your blood and increasing the risk of side effects like drowsiness.

Caffeine (Coffee, tea, energy drinks)

Caffeine is a stimulant and can reduce the calming and sedative effects of diazepam. If you consume a lot of caffeine, you may find the medicine is less effective at treating anxiety or helping you sleep.
