Can I take Cannabis and Ibuprofen together?

Why this happens

Both substances can affect the lining of the stomach and how blood clots (pharmacodynamic effect). Additionally, cannabis may slow down the liver's ability to process certain non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, potentially leading to higher levels of the medicine in your system (pharmacokinetic effect).

Use caution when combining these two. If you need to take them together, use the lowest dose of ibuprofen possible for the shortest time. Watch for signs of stomach pain, dark stools, or unusual bruising. If you feel excessively dizzy or sleepy, avoid driving or operating machinery.

Asthma

Do not take ibuprofen if you have asthma that is worsened by aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), as it can trigger a severe or life-threatening asthma attack.

Stomach ulcers or bleeding

Do not take ibuprofen if you have a history of stomach ulcers, perforation, or bleeding, as it significantly increases the risk of serious gastrointestinal bleeding.

Pregnancy (third trimester)

Do not take ibuprofen if you are more than 6 months pregnant (third trimester), as it can cause serious heart and kidney problems in the unborn baby and complications during delivery.

Psychosis or Schizophrenia

You must not use cannabis if you have a personal or strong family history of schizophrenia or other psychotic disorders, as it can trigger or worsen these conditions.

Driving and operating machinery

It is an offence to drive if your ability is impaired by cannabis. Even if you do not feel 'high', the drug stays in your system and can result in a drug-driving conviction.

Alcohol

Drinking alcohol while using cannabis can significantly increase the sedative effects, leading to extreme drowsiness, dizziness, and impaired coordination. It may also increase the levels of THC in your blood, making the 'high' more intense or unpredictable.

Grapefruit juice

Grapefruit and grapefruit juice can interfere with how your body breaks down certain compounds in cannabis (particularly CBD). This can lead to higher levels of the medicine in your system, potentially increasing side effects.

Fatty meals

If you are taking cannabis in oral forms (like oils or capsules), eating a high-fat meal can significantly increase the amount of the drug absorbed into your system. This can make the effects much stronger than usual. It is best to be consistent with how you take it in relation to food.

Food (General)

While not an interaction that changes how the drug works, it is strongly recommended to take ibuprofen with food or a glass of milk to protect your stomach lining and reduce the risk of indigestion.
