Ok. Hunni, they’re not like paracetamol where you can take 1 when youve got a headache or up to 8 a day if you’ve got a migraine. Adding an extra dose when you’re feeling worse isn’t the way to use them. You need to take the dose every day that the doctor prescribed and see how it goes over a couple of months - if they’re not helping then you need to go back to your doctor and either change the dose or change the medication, according to the drs prescription.
