Take Propecia as prescribed by your doctor. Avoid taking it in larger amounts or for longer than recommended.
Take this medicine with a full glass of water. Propecia can be taken with or without food. Take the medicine at the same time each day. You may need to take Propecia daily for three months or more before you see a benefit. If the drug has not worked for you in twelve months, further treatment is unlikely to be of benefit.
If you stop taking Propecia, you will likely lose the hair you have gained within 12 months of stopping treatment. To be sure this medication is helping your condition and not causing harmful effects, your blood may need to be tested often. Your doctor will also test your prostate specific antigen (PSA) to check for prostate cancer. Visit your doctor regularly.
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
An overdose of Propecia is not expected to produce life-threatening symptoms.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
