The most common class of medication prescribed for all symptoms of OAB is known as antimuscarinics. Antimuscarinics come from the family of anticholinergics and are the standard for reducing the impact of OAB on your bladder and your body.
Antimuscarinic medication blocks the receptors in the bladder’s walls to reduce the muscle activity, usually resulting in a reduction in the frequency and urgency to urinate
Medications that are commonly prescribed as antimuscarinic include:
- Tolterodine (Detrol LA, Detrol)
- Oxybutynin (Ditropan XL)
- Oxybutynin in the form of a skin patch (Oxytrol)
- Oxybutynin gel (Gelnique 3 percent, Gelnique)
- Trospium (Sanctura)
- Solifenacin (Vesicare)
- Darifenacin (Enablex)
- Fesoterodine (Toviaz)
- Mirabegron (Myrbetriq)
Although there aren’t severe side effects commonly associated with these drugs, common side effects include dry mouth and dry eyes. Patients suffering from a dry mouth will overcompensate by drinking more water and may end up aggravating the symptoms of an overactive bladder, rather than reducing them.
Constipation, which is another possible side effect of the drugs, may also end up aggravating your overactive bladder. The skin patch or gel form of these medications may be better suited for most people since they cause fewer side effects. However, your doctor may recommend you sugar-free candy to counter a dry mouth, and eye drops for keeping your eyes moisturized.
