Can I take Promethazine and Vitamin D3 together?

Perché succede

Promethazine is an antihistamine processed primarily by the liver's cytochrome P450 enzymes, while vitamin D3 is a fat-soluble vitamin that undergoes a different metabolic pathway (hydroxylation in the liver and kidneys). They do not interfere with each other's absorption, metabolism, or effects in the body.

You can continue to take both medications as prescribed. As with any supplement, it is best to take vitamin D3 with a meal containing some fat to help with absorption. Promethazine can cause drowsiness, so be aware of how it affects you before driving or operating machinery.

Breathing problems (e.g. asthma, COPD, sleep apnoea)

Promethazine can cause severe breathing difficulties and should be avoided if you have chronic lung disease or sleep apnoea.

Promethazine causes significant drowsiness that can last into the next day. Do not drive or use tools if you feel sleepy or less alert.

Glaucoma (Closed-angle)

Promethazine can increase the pressure inside your eye. If you have closed-angle glaucoma, this medicine could cause a sudden, painful increase in eye pressure (acute glaucoma attack).

Children under 2 years old

Promethazine must not be given to children under 2 years of age because it can cause fatal breathing difficulties (respiratory depression).

Alcol

It is best to avoid or strictly limit alcohol when taking promethazine. Alcohol significantly increases the sedative effects of this medicine, making you feel much more drowsy, dizzy, or uncoordinated. This combination can also lead to dangerous breathing difficulties.
