1. What is Bitamsol and what is it used for

Bitamsol is a combination of two different medicines called solifenacin and tamsulosin in one tablet. Solifenacin belongs to a group of medicines called anticholinergics and tamsulosin belongs to a group of medicines called alpha-blockers.

Bitamsol is used in men to treat both moderate to severe filling symptoms and emptying symptoms of the lower urinary tract caused by bladder problems and by an enlarged prostate (benign prostatic hyperplasia). Bitamsol is used when previous treatment with monotherapy for this condition did not sufficiently relieve the symptoms.

When the prostate gland enlarges, it can cause urinary problems (emptying symptoms) such as delayed urination (difficulty starting urination), reduced urine flow (weak stream), dripping, and a feeling of incomplete emptying of the bladder. At the same time, the bladder is also affected and contracts spontaneously at times when urination is not desired. This causes filling symptoms such as changes in bladder sensation, urgency (having a strong and sudden desire to urinate without prior warning), and having to urinate more frequently.

Solifenacin reduces the involuntary contractions of the bladder and increases the amount of urine that your bladder can hold. Therefore, you can expect to wait longer before you need to go to the bathroom. Tamsulosin allows urine to pass more easily through the urethra and facilitates urination.

2. What you need to know before you take Bitamsol

Do not take Bitamsol if:

  • you are allergic to solifenacin or tamsulosin or any of the other ingredients of this medicine (listed in section 6).
  • you are undergoing renal dialysis.
  • you have severe liver disease.
  • you have severe kidney disease AND you are being treated with medicines that may decrease the elimination of this medicine from the body (e.g. ketoconazole, ritonavir, nelfinavir, itraconazole). Your doctor or pharmacist will inform you if this is the case.
  • you have moderate liver disease AND you are being treated with medicines that may decrease the elimination of this medicine from the body (e.g. ketoconazole, ritonavir, nelfinavir, itraconazole). Your doctor or pharmacist will inform you if this is the case.
  • you have a severe stomach or intestinal disorder (including toxic megacolon, a complication associated with ulcerative colitis).
  • you have a muscle disorder called myasthenia gravis, which can cause extreme weakness of certain muscles.
  • you have increased pressure in the eyes (glaucoma), with gradual loss of vision.
  • you experience fainting due to a decrease in blood pressure when changing posture (when sitting or standing up); this is called orthostatic hypotension.

Tell your doctor if you think you have any of these conditions.

Warnings and precautions

Consult your doctor or pharmacist before starting to use Bitamsol if:

  • you have difficulty eliminating fluid (urinary retention).
  • you have any obstruction of the digestive tract.
  • you are at risk of decreased activity of the digestive tract (movements of the stomach and intestine). Your doctor will inform you if this is the case.
  • you have a tear in the diaphragm (hiatal hernia) or heartburn and/or you are taking medicines that may cause or worsen esophagitis.
  • you have a certain type of nerve disease (autonomic neuropathy).
  • you have severe kidney disease.
  • you have moderate liver disease.

Regular medical check-ups are necessary to monitor the development of the condition for which you are being treated.

This medicine may affect blood pressure, which can cause dizziness, drowsiness, or rarely, fainting (orthostatic hypotension). You should sit or lie down if you experience any of these symptoms until they have disappeared.

If you are going to undergo or have scheduled eye surgery due to cataracts or increased pressure in the eyes (glaucoma), please inform your ophthalmologist that you have previously used, are using, or plan to use this medicine. The specialist can then take the necessary precautions regarding medication and surgical techniques to be used. Ask your doctor if you should postpone or temporarily interrupt taking this medicine when you are going to undergo eye surgery for cataracts or increased pressure in the eyes (glaucoma).

Children and adolescents

Do not give this medicine to children and adolescents.

Other medicines and Bitamsol

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

It is especially important that you inform your doctor if you are using:

  • medicines such as ketoconazole, erythromycin, ritonavir, nelfinavir, itraconazole, verapamil, diltiazem, and paroxetine, which reduce the rate at which Bitamsol is eliminated from the body.
  • other anticholinergic medicines, as the effects and side effects of both medicines may be intensified if you are taking two medicines of the same type.
  • cholinergics, as they may reduce the effect of Bitamsol.
  • medicines such as metoclopramide and cisapride, which may speed up the functioning of the digestive tract. Bitamsol may reduce their effect.
  • other alpha-blockers, as they may cause an undesired decrease in blood pressure.
  • medicines such as bisphosphonates, which may cause or exacerbate inflammation of the esophagus (esophagitis).

Using Bitamsol with food and drinks

Bitamsol can be taken with or without food, according to your preferences.

Pregnancy, breastfeeding, and fertility

This medicine is not indicated for use in women.

In men, abnormal ejaculation (ejaculation disorder) has been reported. This means that semen is not released through the urethra, but instead goes into the bladder (retrograde ejaculation) or that the ejaculated volume is reduced or nonexistent (ejaculatory failure). This phenomenon is harmless.

Driving and using machines

This medicine may cause dizziness, blurred vision, fatigue, and less frequently, drowsiness. If you experience these side effects, do not drive or use machines.

Bitamsol contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; this is essentially "sodium-free"

3. How to use Bitamsol

Follow the instructions for administration of this medicine exactly as indicated by your doctor or pharmacist. If you are in doubt, consult your doctor or pharmacist again.

The maximum daily dose is one tablet containing 6 mg of solifenacin and 0.4 mg of tamsulosin, taken orally. It can be taken with or without food, depending on your preferences. Do not crush or chew the tablet.

If you take more Bitamsol than you should

If you have taken more tablets than you were told to, or if someone else has taken your tablets, contact your doctor, pharmacist, or hospital immediately for advice.

In case of overdose or accidental ingestion, consult your doctor or pharmacist or call the Toxicology Information Service, telephone: 91 562 04 20, indicating the medicine and the amount ingested.

In case of overdose, your doctor may treat you with activated charcoal; emergency stomach lavage may be useful if performed within one hour of overdose. Do not induce vomiting.

Symptoms of overdose may include: dry mouth, dizziness, and blurred vision, seeing things that are not there (hallucinations), over-excitability, convulsions, difficulty breathing, increased heart rate (tachycardia), inability to empty the bladder completely or partially or to urinate (urinary retention), and/or undesired increase in blood pressure.

If you forget to take Bitamsol

Take your next Bitamsol tablet as normal. Do not take a double dose to make up for forgotten doses.

If you stop taking Bitamsol

If you stop taking Bitamsol, your initial symptoms may reappear or worsen. Always consult your doctor if you are considering stopping treatment.

If you have any other questions about the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The most serious side effect that has been observed with a frequency of less than 1 in 100 men during treatment with this medicine in clinical studies is acute urinary retention, which is a sudden inability to urinate.

Angioedema has been reported rarely with tamsulosin and very rarely with solifenacin. In case of angioedema, treatment with Bitamsol should be stopped immediately and definitively.

If you experience an allergic reaction or a severe skin reaction (e.g. formation of blisters and peeling of the skin), you should inform your doctor immediately and stop using this medicine. Treatment and/or measures should be applied.
