I have a question regarding Modafinil which I have had prescribed to me by a Doctor for my hyper insomnia.

However, I forgot to mention to him I am currently taking 50mg Atenelol along with the 10mg of Coversyl.

I am concerned that the 100mg of Modafinil will react badly with my current medication. Mainly only due to what I have read online. I generally take everything I read online as people experience, hence why I am asking for a specialists advice.

Thanking you.

Hello Sir,

Welcome to XXXXXXX com!!

Modafinil is a psychostimulant which is used for excessive daytime sleepiness. (I hope indication of use of this drug in your case is hypersomnia (excessive sleepiness) rather than hyperinsomnia).

This drug has no known interactions with atenolol and coversyl (perindopril) and is not known to increase or decrease their effect. Neither of the two drugs is known to increase or decrease effect of modafinil.

However, since you have the problem of high blood pressure (as I can judge from your medication) your doctor must be knowing this fact. As this drug is not recommended for patients with uncontrolled hypertension (high blood pressure), patient with left ventricular hypertrophy (a complication of high blood pressure) and anginal heart disease. Moreover, patients who have been started on modafinil should check their blood pressure more frequently, especially for first 3 months.

In summary, modafinil is not known to adversely react with your two drugs but is to be taken carefully in patients with high blood pressure hence you must tell this to your doctor, that you have high blood pressure.

I hope I have answered your query. Still feel free to write, if there is any concern.

Wishing you a good health

Thank you so much for your answer. It definately makes me feel more at ease starting a new medication.

I am wondering if starting at 100mg of Modafinil would be ok, or would you suggest a smaller dose. This drug is extremely expensive in Australia ($700) so I dont want to be using more than needed. Also, is this fine to take with my other medication, or should it be taken say 1hour after my blood pressure medication

I also did mean hypersomnia :)

Thank you again Dr.?

Dear Sir,

The usual standard dosage of this drug is 200 mg once per day for most of indications. Hence prescription of your doctor seems to be ok. Moreover, your treating physician knows best about the dose suitable for you and his advise should be followed.

You can take this drug with other medications mentioned by you. However, if taken with food, the absorption may be delayed by ~1 hour (although the total extent/amount of drug being absorbed remains the same).

I do agree with you that it is an expensive medicine.

Hopefully I answered your query to your satisfaction.

Feel free to discuss further.

Thank you Doctor for your response.

I am happy with your answers. I was looking online and found Indian brand called ModAlert. A lot cheaper, i am wondering if you know of this brand.

Again thankyou for your help.

Dear Sir,

MODALERT is a brand from "sun pharma" which is a reputed company in India and we commonly use drugs manufactured by this company.

I wonder if it will be available in Australia at same price!

Wishing you good health.
