Composition of Linaster-5 mg Tablet

Linaster-5 mg Tablet contains Finasteride 5 mg. It belongs to the 5-alpha reductase inhibitor class of medicines.

Uses of Linaster-5 mg Tablet

  • Treatment of benign prostatic hyperplasia (BPH) to reduce enlarged prostate size
  • improve urinary symptoms (weak stream
  • hesitancy
  • incomplete emptying) and lower risk of acute urinary retention and need for surgery.

Key benefits

  • Reduces prostate size over time
  • Improves urinary flow and BPH symptoms
  • Decreases risk of acute urinary retention
  • Reduces likelihood of BPH-related surgery

How Linaster-5 mg Tablet works

Finasteride inhibits 5-alpha reductase (type II), reducing conversion of testosterone to dihydrotestosterone (DHT). Lower DHT levels shrink the prostate over time and improve urine flow and related BPH symptoms.

How to take Linaster-5 mg Tablet

Tablet for oral use. Take as prescribed by the doctor, usually once daily at the same time each day, with or without food. Swallow whole; do not crush or break. Benefits may take 3–6 months of regular use.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take the missed dose of Linaster-5 mg as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.

If you take too much

Taking more Linaster-5 mg than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.

Side effects of Linaster-5 mg Tablet

Most side effects of Linaster-5 mg are mild and settle as the body adjusts. Reported side effects include:

  • Decreased libido
  • erectile dysfunction
  • ejaculation disorder
  • decreased semen volume
  • breast tenderness or enlargement
  • rash
  • dizziness

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Safety advice for Linaster-5 mg Tablet

AlcoholUse with caution (no specific interaction, but alcohol may worsen urinary symptoms and dizziness)
Habit formingNo

Warnings and precautions

For use in men only. Not for women/children. Finasteride can cause abnormalities in a male fetus—pregnant women or those who may become pregnant should not handle crushed/broken tablets. Inform doctor if you have liver disease or any breast lumps/pain or nipple discharge. May lower PSA levels and affect prostate cancer screening—tell your doctor/lab that you take finasteride. Seek medical help for allergic reactions or breast changes.

Interactions with other medicines

No major clinically significant interactions are common; however, inform doctor about all medicines. Caution with other BPH medicines (e.g., alpha-blockers like tamsulosin) due to additive symptom relief/low BP risk, and with strong CYP3A4 inhibitors/inducers (potential to alter finasteride levels though usually not clinically significant).

How to store Linaster-5 mg Tablet

Store below 25°C in a cool, dry place, protected from light and moisture. Keep in original strip and out of reach of children.
