Can I take Vamelan if I drink Iodomarin and Betaserc in the morning?

Yes, you can, especially if the medication is used as directed by your doctor. 

There are no contraindications to the simultaneous use of the drugs mentioned in the question.
However, it should be remembered that while taking Betaserc, you should avoid taking antihistamines and monoamine oxidase inhibitors (MAOIs) at the same time. Antihistamines can reduce the effectiveness of Betaserc, and monoamine oxidase inhibitors can increase its effects, which can lead to more side effects.

Additionally, caution is advised when consuming large amounts of coffee during treatment with Betacardia12. The tablets should be taken with water, as e.g. coffee and tea can reduce the absorption of the active substances of the drug.
