Instarise 100 mg Tablet is used for treatment of Erectile dysfunction.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Instarise 100 mg Tablet contains Sildenafil (100mg). It belongs to the Prescription-only medicine class of medicines.
Treatment of Erectile dysfunction
Instarise 100mg Tablet is a phosphodiesterase-5 (PDE-5) inhibitor. It works by relaxing the blood vessels in your penis, thereby increasing blood flow into the penis on sexual stimulation. This helps you achieve and maintain a hard, erect penis suitable for sexual activity.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Instarise 100mg Tablet may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Instarise 100mg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine may be harmful — seek medical advice immediately. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Instarise are mild and settle as the body adjusts. Reported side effects include:
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.

This is a prescription-only medicine. Take it exactly as your doctor has directed, for the period directed. Do not share it with anyone else, even if their symptoms seem the same. Tell your doctor about every other medicine, supplement and herbal product you take. Report any unexpected or severe symptom to your doctor rather than stopping on your own.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Your doctor will confirm this medicine is suitable for you.
Give your doctor and pharmacist a full list of everything you take.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Take Instarise 100mg Tablet about 30-60 minutes before anticipated sexual activity as directed by your doctor. Do not take Instarise 100mg Tablet more than once in 24 hours. Instarise 100mg Tablet may cause dizziness, sleepiness, or fainting, so avoid driving or operating machinery until you know how it affects you. Avoid alcohol while taking Instarise 100mg Tablet, as it may increase dizziness or fainting risk. Do not combine Instarise 100mg Tablet with nitrates (used for chest pain) or recreational “poppers,” as this may cause a dangerous drop in blood pressure. Avoid using Instarise 100mg Tablet with other erectile dysfunction or premature ejaculation medicines unless advised by your doctor. Inform your doctor if you take medicines for heart problems, blood pressure, or chest pain. Seek urgent medical attention if you develop chest pain, severe dizziness, fainting, or shortness of breath during sexual activity. Seek immediate medical care if an erection lasts longer than 4 hours (priapism). Tell your doctor if you have heart disease, liver or kidney disease, seizures, or bleeding disorders before using Instarise 100mg Tablet. Consult your doctor if symptoms persist despite treatment, as lifestyle factors such as stress, sleep, and overall health may also need attention.
