Ask your doctor, pharmacist or other healthcare professional about any side effects associated with the medication and any specific recommendations about how and when to take it. Virtually any drug will occasionally cause an unwanted reaction. A side effect is a reaction or consequence of medication or therapy that is additional to the desired effect of the medicine.
Some side effects are predictable.
For example, some antihistamines can cause drowsiness and many cancer therapies can cause hair loss. Some adverse reactions are unexpected, may be serious, and are unpredictable. Serious adverse reactions are also, in general, rare. Call your doctor, pharmacist, or other healthcare professional immediately if you think you've experienced an adverse drug reaction to your medication. Do not be afraid to ask your doctor, pharmacist or other healthcare professionals any questions or concerns you have about your medications.
