Yes, you can, especially if the medication is used as directed by your doctor. These medicines do not have clinically relevant interactions with each other that would preclude their combined use.

Due to the fact that all of the listed medications are prescription only, please follow your doctor's instructions. I also encourage you to inform your doctor about all the medications and dietary supplements you use, which will allow you to choose safe and effective pharmacotherapy.

You can check the availability of medicines and book them at the pharmacy of your choice and pick them up after presenting your prescription:
