Why your using diclofenac we don t know but using pain killer with hypertensive medicine cause poor control of blood pressure. But better to take long acting nifidipine/nimodipine for SAH. You can take up 180mg per day. Nimodipine is indicated to reduce poor outcome related to aneurysmal subarachnoid hemorrhage. While studies have shown benefit regarding severity of neurologic deficits caused by cerebral vasospasm following SAH, no evidence exists that nimodipine either prevents or relieves spasms of cerebral arteries. Along with gabapentin you can take phenytoin. Low salt diet may help. But pain management important. In place of metaprolol you can use Labetalol. blocks alpha-, beta1-, and beta2-adrenergic receptor sites, decreasing blood pressure. Why your using tizanidine not mentioned?? Are you suffering from amoebic dysentery you can continue. You can continue one benzodiapine also.
