What is Istin?
The active substance in Istin is amlodipine, a substance that dilates blood vessels. Istin causes the blood pressure to decrease and the heart has to work less hard. You can order Istin online through the pharmacies that work together with Dokteronline.com. The required prescription is provided through an online consultation.
What is this medication used for?
Doctors prescribe Istin among others against high blood pressure. Elevated blood pressure provokes little or no physical symptoms, but is harmful to the arteries and the heart. If the blood pressure is chronically high, this can increase the risk of cardiovascular disease. Istin ensures a lower blood pressure, which reduces this risk. Istin is also sometimes used to treat certain heart conditions (for example: angina pectoris) and Raynaud's phenomenon (a circulation problem in the hands and feet).
How to use Istin?
Take the tablet as a whole, with or without food. The action of this drug is sometimes affected by grapefruit (juice). This may increase the risk of side effects. Do not eat or drink grapefruit juice (juice) when you are using Istin. Keep using this medicine as long as the doctor recommends it.
The partner pharmacies offer Istin online in various strengths. A doctor knows which strength will suit your symptoms. Unless a doctor prescribes otherwise, the usual starting dose for high blood pressure is as follows:
- Adults: one tablet of 5 or 10 mg once a day.
- Children aged 6 years and more: once a day a half or a whole tablet of 5 mg.
For the treatment of other diseases (heart disease, Raynaud's phenomenon) a different dosage may apply. Do not deviate from the prescribed dosage and read the instructions before use.
Istin can cause side effects, although not everybody seems to experience this. Possible side effects of Istin include:
- Edema (fluid retention);
- Muscle cramps;
If you suffer a lot from side effects or if you experience any that are not mentioned in the patients' leaflet, please consult a doctor.
When is it best not to use this medication?
Istin is not a suitable medicine for everyone. Do not use this medication if you:
- are hypersensitive to amlodipine or any of the excipients used;
- are being treated with rifampicin (a medicine against infections);
- recently have suffered a heart attack.
