Cialis (Tadalafil)

Do's

• The manufacturer directs to swallow the regular tablet whole; however, similar drugs in immediate-release tablet form can be split or crushed.
• Follow your healthcare provider’s directions on how to take the medication.
• The frequency and timing of Cialis administration depend on the specific medical condition being treated, whether it's for erectile dysfunction (ED), benign prostatic hyperplasia (BPH), or a combination of both.
• Cialis may be prescribed in two ways for treating ED. The first way is to take it as needed, usually at least 30 minutes before sexual activity. The second way is to take it regularly, once a day every day. The dosage for ED depends on how it is being taken, and the effect on sexual ability may last up to 36 hours.
• To treat the symptoms of BPH, Cialis is taken as directed by a healthcare provider, usually once a day. If also taking finasteride with this medication to treat symptoms of BPH, discuss with your healthcare provider about the duration of taking this medication.
• If taking Cialis to treat both ED and BPH, it is taken as directed by a healthcare provider, usually once a day. Sexual activity may be attempted at any time between doses.
• Cialis can be taken with or without food. It should be taken exactly as prescribed by your health care provider, following all directions on the prescription label and reading all medication guides or instruction sheets.

The dosage of Cialis is determined based on the individual's medical condition, response to treatment, and other medications being taken. Inform your healthcare provider about all the products being used, including prescription drugs, nonprescription drugs, and herbal products.
