Bladder antispasmodics

Medication for use with bladder instability

  • Medication for the treatment of bladder instability

    Oxybutynin:

    Used for bladder instability.  It is not acceptable for short-term use prior to bladder surgery.  Only the sustained-release formulation is permitted and pilots should be advised to keep themselves well hydrated before and during flights.

    Side-effects to enquire about are mainly anti-cholinergic such as dry mouth, blurred vision and drowsiness.  If these do not occur in the first few months they are extremely unlikely to occur later.

    Class 1 Unfit for one month

    OML from one to six months assuming a lying/standing BP shows no evidence of postural hypotension.
    Unrestricted may be possible after six months

    Class 2 Unfit for one month

    OSL from one to three months assuming a lying/standing BP shows no evidence of postural hypotension.
    Unrestricted is possible at three months if specific enquiry for side-effects is negative.
