Can I take Danazol and Tramadol together?

Drug interaction guide

Taking danazol and tramadol together can increase the amount of tramadol in your bloodstream. This makes you much more likely to experience serious side effects, such as extreme sleepiness, breathing difficulties, and a rare but dangerous condition called serotonin syndrome (which causes confusion, sweating, and shaking). It may also increase the risk of having a seizure.

Why this happens

Tramadol is broken down in the liver by specific enzymes. Danazol blocks these enzymes, preventing the body from clearing the tramadol. This leads to a build-up of the painkiller to potentially toxic levels.

You should speak to your doctor before taking these two medicines together. Your doctor may need to adjust your dose of tramadol or monitor you more closely for side effects. If you feel unusually dizzy, sleepy, or have trouble breathing, seek medical help immediately.

Pregnancy

You must not take danazol if you are pregnant or planning to become pregnant. It can cause the development of male physical characteristics in a female foetus. You must use effective, non-hormonal contraception (such as condoms) while taking it.

Blood clots (Thromboembolism)

Danazol significantly increases the risk of serious blood clots. Seek immediate medical help if you experience sudden leg swelling, chest pain, or shortness of breath.

Liver disease

Danazol can cause serious liver damage and non-cancerous liver tumours. You will need regular blood tests to monitor your liver function while taking this medicine.

Epilepsy or history of seizures

Tramadol can increase the risk of having a fit (seizure), even at the recommended dose. This risk is higher if you already have epilepsy or are taking certain antidepressants.

Asthma or breathing problems

Tramadol can cause dangerous breathing difficulties (respiratory depression). You must not take it if you have severe asthma or significant breathing problems.

Alcohol

It is best to avoid or strictly limit alcohol while taking danazol. Combining danazol with alcohol can cause you to feel nauseous or short of breath (a disulfiram-like reaction). Additionally, both danazol and alcohol can put strain on your liver, and using them together increases the risk of liver damage.
