How to take CLARUS

Depending on your dosage of Clarus, you’ll probably take it for at least 12 to 16 weeks. This is called a course of therapy. If you require a second course of therapy, it will start eight or more weeks after your first course is done.

Read your prescription label carefully and take the exact amount of medicine prescribed by your doctor. The amount of Clarus you should take has been chosen just for you. Your dose of Clarus is based on your body weight, and your doctor may change your prescribed dose from time to time, so it’s important to check the label every time you fill your prescription. If you have any questions, call your doctor.

The soft gelatin Clarus capsule is easy to swallow. Do not chew or suck on the capsule. Swallow your Clarus capsule whole with a full glass of liquid. It should be taken with food or just after a meal. If you forget to take your dose at mealtime, you can take it with a later meal that day, but don’t take more Clarus® in one day than your doctor has prescribed. The reddish brown capsule is the 10 mg size and the orange brown capsule is the 40 mg size.

How to store CLARUS

You don’t need to refrigerate Clarus but it should be kept in its original package at a temperature of 15-30°C, protected from sunlight and heat.

Be sure to keep Clarus out of the reach of children.
