Cialis (tadalafil) tips from pharmacists

• You can take Cialis in one of two ways - either on a daily basis or as needed. If you have sex occasionally, you can take it as needed. On the other hand, if you desire more spontaneity in sexual activity, you can take it every day.
• The side effects of Cialis, like back pain or muscle ache, usually improve within a few days. However, if they are severe or do not go away, talk to your doctor.
• If you have an erection that is painful and lasts more than 4 hours, go to the emergency room. 
• Cialis does not prevent pregnancy or protect you against sexually transmitted diseases. Take proper precautions to prevent STDs and pregnancy.
