Can the use of Tamex 0.4mg Tablet increase blood sugar levels?

Does Tamex 0.4mg Tablet cause weight gain?

No, Tamex 0.4mg Tablet does not usually cause any increase in weight, even on long-term use. If you experience any weight gain while taking the medication, then consult your doctor to identify the cause of the weight gain.

When does Tamex 0.4mg Tablet start to work?

An improvement in urine flow can be seen in 4 to 8 hours after taking Tamex 0.4mg Tablet. However, it may take 2 to 4 weeks for the full effect to come.

Can I take Tamex 0.4mg Tablet with vitamin D?

Yes, Tamex 0.4mg Tablet can be taken with vitamin D. No harmful effects or interactions have been reported when these are used together.

Why does Tamex 0.4mg Tablet cause dizziness?

Tamex 0.4mg Tablet dilates the blood vessels and leads to the accumulation of blood in the extremities (ends of the arms and limbs). This restrains the proper flow of blood to the brain, thereby causing the blood pressure to fall with the sudden change in posture. As a result, the patient may experience dizziness, lightheadedness, fainting, spinning sensation, and vertigo.

Why should I stop taking Tamex 0.4mg Tablet before my cataract surgery?

Tamex 0.4mg Tablet can cause floppy eye syndrome, in which the muscles of the iris become floppy, and the pupil constricts unexpectedly during cataract surgery. So, when the eye surgeon actually needs a dilated pupil, it will constrict and restrict the field of surgery, which can affect the surgical outcomes.

Can Tamex 0.4mg Tablet cause frequent urination?

No, Tamex 0.4mg Tablet does not cause frequent urination. In fact, this medicine increases the urine flow and decreases the urge to urinate frequently, which is a symptom of benign enlargement of the prostate gland. This condition also leads to a weak stream while urinating, and hence, the patient is not able to empty the bladder. Tamex 0.4mg Tablet is used to treat all such symptoms related to urine flow in patients with benign enlargement of the prostate gland.

What are the long-term effects of taking Tamex 0.4mg Tablet?

Usually, Tamex 0.4mg Tablet does not cause any side effects in patients with benign enlargement of the prostate gland. However, long-term use of Tamex 0.4mg Tablet may increase the chances of having infection, rhinitis, pain, and pharyngitis. Its long-term use may also cause abnormal ejaculation, blackouts, faintness, lightheadedness, dizziness, and decreased blood pressure.

Apart from taking medicines, what should I do to manage my prostate symptoms?

Simple lifestyle changes can help you manage your symptoms better. Try to urinate when you first get the urge. However, take care not to strain or push to empty your bladder. Avoid drinking fluids (especially alcohol and caffeine) a few hours before bedtime or going out. Also, you should not take any other medicine without consulting your doctor because some medicines can increase your urge to urinate.
