Finding an answer

I’ve had quite a few interesting patient enquiries this week for which I’ve needed to contact the relevant pharmaceutical companies. Some of them are:

• Can you mix Movical sachets in warm water? Answer: The company is aware that this has been done but doesn’t have any stability data and so doesn’t recommend it.

• There is grapefruit flavouring in Idrolax sachets so will this interact with simvastatin? Answer: No.

• Can a person who has had a cataract operation two months previously start to use Opticrom eye drops again for an allergy? Answer: Yes.

• Can a patient with chromic urticaria increase the maximum licensed daily dose of 180mg Fexofenadine (on the advice of their GP)? Answer: The company has studies to show that doses far in excess of 180mg daily can be administered safely but a consistent clinical benefit has not been shown.
