Can I take Morphine and Solifenacin together?

Varför detta händer

Both drugs have 'anticholinergic' effects, meaning they slow down the movement of the gut and the bladder. When used together, these effects add up, making it much harder for your body to move waste through your system or empty your bladder.

Use this combination with caution. Ensure you drink plenty of water and eat a high-fibre diet to prevent constipation. If you find it difficult to urinate, or if you experience severe stomach pain or confusion, contact your doctor immediately. Your doctor may need to adjust your doses.

Respiratory conditions (e.g. asthma, COPD)

Morphine can cause life-threatening breathing difficulties. Do not take this medicine if you have severe asthma or breathing problems.

Opioid dependence and withdrawal

Morphine carries a high risk of addiction and dependence. Long-term use can lead to withdrawal symptoms if stopped suddenly; always follow a tapering schedule.

Glaucoma

Do not take solifenacin if you have narrow-angle glaucoma that is not being effectively treated, as it can increase the pressure in your eyes.

Urinary or gastric retention

Do not take solifenacin if you have severe difficulty passing urine or if you have a condition where your stomach empties very slowly (gastric retention).

Alkohol

It is best to avoid or strictly limit alcohol while taking morphine. Combining alcohol with morphine significantly increases the risk of dangerous side effects, such as extreme sleepiness, breathing difficulties, and a potentially fatal overdose.

Grapefruit juice

Avoid drinking large amounts of grapefruit juice. Grapefruit can increase the level of solifenacin in your blood, which may increase the risk of side effects like dry mouth, blurred vision, and constipation.

Caffeine (Coffee, Tea, Energy drinks)

While not a direct chemical interaction, caffeine is a bladder irritant and a diuretic. Since solifenacin is used to treat overactive bladder symptoms, consuming caffeine may reduce the effectiveness of your treatment.
